The extinction at the end of Permian 252 million years ago caused the extinction of about 81% marine species and 89% terrestrial species. The main reason is believed to be the environmental change caused by large-scale volcanic eruption, but there is still no direct evidence that environmental factors affect terrestrial ecosystems. In cooperation with foreign counterparts, researchers in China discovered the direct evidence that the destruction of the ozone layer led to the extinction of terrestrial life at the end of Permian by studying the changes of "sunscreen" content in fossil pollen grains during this period.

The research results were published online in the internationally renowned journal Science Advances on January 6, 2023.

Volcanic eruption led to mass extinction of land? There was a lack of direct evidence

The extinction event at the end of Permian was the largest extinction event in Phanerozoic. Scientists generally believe that the increase of global greenhouse gases caused by the eruption of Siberian igneous province at the end of Permian, global warming and ocean acidification may be the main causes of this extinction. However, there are still many debates about how these environmental factors affect terrestrial ecosystems.

Some palynologists have found some deformed spores and pollen in the continental Permian-Triassic transition section. It is speculated that these deformed spores or pollen may be caused by the increase of ultraviolet radiation induced by the destruction of the global ozone layer caused by halogen elements ejected from the Siberian igneous province. However, the study of abnormal spores and pollen produced in modern plants shows that the environmental background of these abnormal pollen and spores is very complicated, and drought, air pollution and plant trauma may all induce abnormal spores or pollen to be produced in plants. Therefore, the discovery of a small number of abnormal spores and pollen in the continental Permian-Triassic transition section cannot directly prove that there was an increase in ultraviolet radiation caused by the global ozone hole during the extinction at the end of Permian.

Using the content of "sunscreen" to deduce the intensity of atmospheric ultraviolet radiation

Plants need sunlight for photosynthesis to provide energy for plant growth, but at the same time, it is necessary to avoid the damage of harmful ultraviolet rays in sunlight to genetic information in plants, especially in plant reproductive cells (spores and pollen). In order to adapt to the terrestrial radiation environment, terrestrial plants have evolved some regulatory mechanisms to reduce the damage of ultraviolet rays to plants. In the germ cells of plants, this mechanism is manifested in that there are a large number of compounds-coumaric acid and ferulic acid-in the outer walls of plant spores and pollen, which are very similar in function to "sunscreen cream". These compounds can form resonance-stable phenol free radicals and resist the oxidation caused by ultraviolet rays, thus protecting fragile spores and pollen and providing guarantee for the spread and reproduction of terrestrial plants.

Modern botanists have observed that plants can automatically adjust the content of "sunscreen" on the outer wall of their germ cells according to the surrounding ultraviolet radiation environment, and these "sunscreen" can be stored in the outer wall of inert spores and pollen for a long time. Therefore, in theory, researchers can determine the content of "sunscreen" in these spores and pollen, and deduce the intensity of atmospheric ultraviolet radiation in geological history.

"Sunscreen" is difficult to digest and has low nutrition, or leads to the extinction of insects.

According to Liu Feng, a researcher at Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences, the research team quantitatively measured coumaric acid and ferulic acid in 1011 pollen grains from Permian-Triassic transition section in southern Tibet, China. Through the big data analysis of infrared spectra produced by these pollen, the research team found that during the extinction at the end of Permian, the contents of coumaric acid and ferulic acid in the outer wall of pollen in the stratum were significantly higher than those in fossil pollen before and after extinction, which directly proved that there was an increase in global ultraviolet radiation during the extinction at the end of Permian.

The increase of ultraviolet radiation in the air has a far-reaching impact on the whole terrestrial ecosystem. Because ultraviolet rays not only have a strong killing effect on plant germ cells, but also cause damage to plant mesophyll cells. In order to resist the damage of ultraviolet rays to mesophyll cells, plants will synthesize lutein, coumaric acid and ferulic acid in their leaves, which will reduce the synthesis of chlorophyll accordingly, leading to the weakening of photosynthesis of plants, which will further weaken the absorption capacity of plants for greenhouse gases, further aggravating the global greenhouse gas increase caused by volcanic eruption at the end of Permian.

In addition, lutein, coumaric acid and ferulic acid in mesophyll are compounds that are difficult to digest and have low nutritional value for herbivores and insects, so the increase of ultraviolet radiation indirectly affects the terrestrial food chain, which may be the main reason for the extinction of terrestrial herbivores and insects at the end of Permian.

　　The brand awareness of Haier refrigerator is very high. Many people have heard that Haier Commander Refrigerator and Haier Refrigerator are the same. What is the difference between Haier Commander Refrigerator and Haier Refrigerator? Why is the price gap so big? The following small series will give you a specific analysis. Let’s take a look.

　　Haier tongshuai refrigerator

　　Commander-in-Chief is the third sub-brand of Haier Group after Haier and casarte, and it is a customized home appliance brand launched by Haier Group under the background of the Internet era. In 1998, the commander-in-chief brand was exported to the European market as an overseas marketing platform.

　　Haier Group products have three brands, Haier, casarte and Commander-in-Chief. Haier refrigerator and Haier Commander refrigerator are both brands of Haier refrigerators, but they are put into different markets. Commander series belongs to Haier’s low-end and mid-end brands. In the early stage, home appliances went to the countryside as Commander refrigerators, and casarte series was the high-end brand of refrigerators.

　　The product appearance of Haier refrigerator and Haier commander refrigerator may be different. Haier staff said that Haier’s commander-in-chief brand and Haier brand refrigerator are the same in terms of development and production technology, but the brands are different and the materials of some refrigerators are different. The product quality is the same, and the commander-in-chief also provides product customization.

　　Generally, Haier refrigerators have refrigerator specification labels (or refrigerator nameplates) attached to the inner wall of the refrigerating room or the back of the refrigerator, which indicate the specifications, models (such as "BCD-216YH silver gray" for a 216-liter silver gray refrigerator), power, circuit diagram and so on. Haier’s products exclusively used in urban and rural areas are generally not fully labeled or not labeled at all, but the performance of the products is the same as other products. For the refrigerators exclusively used, only the refrigerators are more suitable for the supply and demand sides.

　　The difference between Haier commander refrigerator and Haier refrigerator is here for everyone. You should be able to distinguish between the two refrigerators now, and also introduce the relationship between them. In the future, you can clearly distinguish when buying Haier refrigerator. I hope the content introduced above can help those in need.

A single mother with cancer turned to the government for help. Source: Leader Message Board official website screenshot

　　Recently, a single mother suffering from cancer in Changgou Village, Dashuiquan Town, Xinglong County, Chengde City, Hebei Province left a message on People’s Daily Online "Local Leaders Message Board" asking for help, hoping that the government could help her find a rescue agency to raise and take care of her adopted daughter with intellectual disability.

　　The Social Situation and Public Opinion Office of Chengde Municipal Committee has replied at the bottom of the message board that the relevant units of Chengde Civil Affairs Bureau and Xinglong County have carefully checked. After active coordination, relevant issues have been properly solved.

　　On July 5, a staff member of the Civil Affairs Bureau of Xinglong County, Chengde City told The Paper that at present, the child has been sent to Chengde Welfare Institute, which is responsible for his daily life; The mother of the child still needs regular medical treatment. At present, in view of the above situation, relevant problems have been arranged to be solved.

　　On July 5th, a staff member of Xinglong County Party Committee Office told The Paper that the mother was divorced, suffering from advanced cervical cancer, and her adopted child was mentally disabled. A month ago, they raised about 6,000 yuan for it and have completed the last phase of chemotherapy. At present, the mother is in good health and will be reviewed in three months. "The follow-up cost is not very high. She is now working with her friends and earning a little money. There is nothing wrong with life at present. " The staff member said that in the next step, after her body recovered, the mother was going to set up a stall in the market.

　　The above-mentioned staff said that they would continue to follow up her physical condition and provide corresponding help.

　　The staff member also mentioned that at first, the mother had no time to rest because she needed to take care of her children alone for 24 hours. She thought she had no hope of recovery, so she gave up treatment and went through the procedure of donating her body. At present, the child has been arranged to be taken care of by Chengde Welfare Institute. He said that local volunteers will also be regularly organized to go to the welfare home with the mother to see the children.

　　On the same day, a staff member in charge of subsistence allowances in Xinglong County said that they had raised the low premiums of mother and daughter to the highest standard. Originally, the mother’s monthly fee was 245 yuan, and the daughter’s monthly fee was 255 yuan. Now, both of them have been raised to 400 yuan per person per month.

　　The Paper noticed that the aforementioned single mother wrote on the message board that in 2006, she lost her fertility due to tubal blockage and ectopic pregnancy surgery; In 2013, her mother adopted a baby girl from a pair of Tianjin parents under the age of 18. Subsequently, the baby girl was raised by her, but unfortunately she suffered from encephalitis, which caused secondary mental disability. To this end, she borrowed 300,000 yuan to treat her children.

　　She also wrote that she divorced her husband in 2019. Because the opposite sex was not related by blood, her ex-husband could not be the guardian of her adopted daughter alone, and the court awarded her custody of the child. The child is 9 years old this year. He can’t take care of himself and needs long-term care. In July 2020, she was diagnosed with advanced cervical cancer. After radiotherapy and chemotherapy, she is still receiving follow-up treatment. However, because she found it too late to surgically remove the lesion, she was extremely weak and thus lost her ability to work.

　　"Give the child a chance to live when I have to say goodbye to this world." The single mother wrote.

　　The Beijing Municipal Health and Health Commission, the Municipal Education Commission and the Municipal People’s Social Security Bureau jointly released the work plan for influenza vaccination in Beijing in 2022. The influenza vaccination work in this city will be implemented in batches in mid-September, and the free vaccination work is initially scheduled to end at the end of November.

　　Free influenza vaccination population is — —

　　Older people over the age of 60 with the city’s resident ID card/social security card;

　　All primary and secondary school students (including domestic and foreign students in primary schools, general middle schools, technical secondary schools, vocational high schools, technical colleges, reform schools and special education schools);

　　Emergency support personnel for major activities identified by the health administrative departments of all districts (including frontline personnel for epidemic prevention and control in COVID-19).

　　Routine immunization clinics in all districts are responsible for providing self-funded and free influenza vaccination services, and actively organizing qualified medical institutions and medical personnel within their respective jurisdictions to provide self-funded influenza vaccination services. In areas with large vaccination needs, at least one qualified secondary and above medical institution should be organized to provide vaccination services during this year’s influenza vaccination. Choose suitable places in each district to set up temporary inoculation points reasonably, and when necessary, open temporary inoculation points of COVID-19 vaccine to meet the population’s centralized inoculation demand. Each district should take various measures to further improve the vaccination service capacity in its jurisdiction, such as setting up district-level mobile vaccination teams, extending the vaccination time of vaccination clinics, setting up weekend clinics, and encouraging physical examination centers to set up vaccination clinics.

　　In 2022, the city will further promote the influenza vaccine appointment vaccination system under the situation of epidemic prevention and control in COVID-19. Each district is responsible for organizing primary and secondary schools, secondary specialized schools, technical colleges, old-age care institutions, villages/neighborhood committees and other units under the guidance of the district CDC to make an appointment and docking with the vaccination clinics in the jurisdiction for free vaccination. Citizens who are willing to vaccinate can make an appointment at the vaccination clinic through various appointment methods such as internet, telephone and on-site appointment.

　　The first batch of vaccination work is scheduled to start in mid-September, mainly for the elderly aged 60 and above in Beijing, and the vaccination publicity and mobilization of students in primary and secondary schools, secondary specialized schools and technical colleges will be started simultaneously.The second batch is scheduled to start in late September, mainly for students in primary and secondary schools, secondary specialized schools and technical colleges, and simultaneously start the self-funded vaccination of influenza vaccine in the city. The third batch is scheduled to start in early October, mainly for emergency support personnel of major events (including front-line personnel of epidemic prevention and control in COVID-19). If there is no special reason, the free vaccination of influenza vaccine in the city is initially scheduled to end at the end of November.

　　All vaccination clinics should arrange the vaccination work of schools, old-age care institutions and other collective units in advance to avoid large-scale vaccination in concentrated periods. At the same time, do a good job in registering the demand for pneumococcal vaccination, arrange vaccination reasonably, and provide joint vaccination services for pneumococcal polysaccharide vaccine and influenza vaccine for the elderly.

　　All vaccination clinics should strengthen vaccine management, standardize vaccination operations, strictly implement epidemic prevention and control measures such as daily ventilation and disinfection, temperature measurement, code test, negative nucleic acid test, and keeping a one-meter line at the vaccination site to ensure vaccination safety. At the same time, they should take various convenient service measures such as cold protection, rain protection and anti-skid, and do a good job in vaccination warm-hearted service and humanistic care for key groups such as the elderly and students, so as to further enhance the comfort and satisfaction of the citizens.

　　On May 24 this year, a newborn finless porpoise cub was separated from its mother and ran aground on the beach. Its fate touched the hearts of countless Nanjing people. But after 18 hours of emergency rescue, the "smiling angel" left us. "Even with artificial assistance, it is still difficult for cubs who leave their mothers to survive." Professor Yang Guang, Dean of the School of Life Sciences of Nanjing Normal University, told a cruel truth: the fate of this little finless porpoise may have been doomed. He believes that the only way to avoid the recurrence of the tragedy is to improve the ecological environment of the Yangtze River in all aspects, one of which is to restore the bait resources and prevent the finless porpoise from starving.

　　Yesterday morning in Nanjing Jiangbin Park, all the 1 million fry subscribed by deji plaza were put into the Yangtze River. The reporter learned that this is the first time in China that an enterprise has initiated a release activity for the protection of finless porpoises.

　　Intern Xu Linchen Yangzi Evening News All-Media Reporter Zhang Ke

　　A rescue that was doomed from the beginning.

　　The latest hot event about the finless porpoise was the "beaching incident of finless porpoise cubs" in Nanjing at the end of last month. This little finless porpoise was found by the public on the river beach of Yanziji Wharf at 4 pm that day. It was born about two or three days ago, but it hasn’t opened its eyes yet, and its breath is weak. At that time, the people involved in the rescue contacted the experts of Nanjing Underwater World, and on the other hand, the water police drove speedboats to patrol the river to find the trace of the female finless porpoise. "The finless porpoise is a mammal, and the newborn calf must be with its mother. This little finless porpoise must have been separated from its mother when it appeared alone, and the mother finless porpoise is likely to come back to find the child." Jiang Meng, secretary-general of the Nanjing finless porpoise protection association who participated in the rescue at that time, said.

　　Until 8 o’clock in the evening, the female finless porpoise was still not found, and the little finless porpoise was forced to transfer to the underwater world for treatment. Regrettably, at 10 o’clock the next morning, the little finless porpoise died unfortunately before he opened his eyes to see the world. At that time, Jiang Meng waited all night in the underwater world and witnessed the whole process. He told the Yangzi Evening News reporter that the finless porpoise was once in good condition and could eat and breathe with artificial assistance. "But in the end, it was short of breath and emotional anxiety, and experts took various emergency measures. All have no effect." Jiang Meng said.

　　The finless porpoise is a clever but fragile creature. Its intelligence is close to that of gorillas, and it knows how to hunt and prey collectively. However, the underage or newborn finless porpoise has almost no ability to live independently. Professor Yang Guang, dean of the School of Life Sciences of Nanjing Normal University, told the Yangzi Evening News reporter that the cub can’t eat and prey independently without its mother, and it must rely on breast milk for nutrition. "About half a year after birth, cubs can learn to live independently."

　　The Yangzi Evening News reporter learned that the adult finless porpoise had survived under artificial rescue, but the cubs have not been successfully rescued so far. "The finless porpoise is too sensitive to the outside world. The artificial environment is different from nature, which will make it nervous. If the tension continues, it will lead to endocrine disorders and illness, which is fatal to the cubs." Professor Yang Guang said.

　　What caused the little finless porpoise to be separated from its mother? "It may be a sudden encounter with a jet stream or an undercurrent, or it may be a human activity such as a ship sailing, a sudden whistle or a sudden increase in the sound of a motor, which may cause fright." Professor Yang Guang believes that the impact of human activities on the ecology of the Yangtze River is really interfering with the normal life and reproduction of finless porpoises.

　　Finless porpoises at the top of the food chain but not enough to eat.

　　Jiang Meng, secretary-general of Nanjing finless porpoise protection association, often observes finless porpoises on the upper and lower reaches of the Yangtze River Bridge, and organizes volunteers to assist fishery administration departments to release finless porpoises’ food such as fry and bait into the Yangtze River. "Many times when feeding, we found that the finless porpoise soon emerged on the nearby river." The water of finless porpoise is called "Jiang Zhu worships the wind", which was once a unique scenery on the Yangtze River. Today, however, there is something bitter behind such a scene. He believes that the gathering and appearance of finless porpoises during feeding, on the one hand, shows that finless porpoises are very smart creatures, on the other hand, also shows that finless porpoises are starving and very hungry for food. Jiang Meng once paid attention to the records of finless porpoises found in recent years. He found that "finless porpoises were originally round and chubby, but many bodies were salvaged and found to be very thin, and after dissection, they found that their stomachs were empty."

　　Relevant data show that the natural catch of fisheries in the Yangtze River is decreasing year by year, from 540,000 tons in 1954 to 70,000 tons in 2012. There are 175 endemic species in the Yangtze River, and more than half of them have been lost in the past five years. The long-term monitoring data of many scientific research institutions, such as the Institute of Aquatic Sciences of Chinese Academy of Sciences, show that the number of fry of the "four big fish" in the Yangtze River has dropped sharply, from more than 30 billion in the 1950s to less than 100 million in 2013.

　　The reporter learned that in 2016, the closed fishing period of the Nanjing section of the Yangtze River was adjusted from March 1 to June 30, and it was extended from the past three months to four months. This move was to strengthen the protection of finless porpoises and other aquatic organisms in the Yangtze River. However, before the effective intervention of government departments, the phenomenon of cool fishing and overfishing in the Yangtze River was more serious. Illegal fishing activities such as fish frying, electric fishing, "ecstasy" and homeless nets are draining the fishery resources in the Yangtze River.

　　"finless porpoises have no natural enemies in the Yangtze River. They can be said to be creatures at the top of the food chain. They are not very picky eaters, as long as they are fish within 20 cm in length. However, due to the exhaustion of fisheries in the Yangtze River, finless porpoises are in a state of starvation. " Professor Yang Guang said that in addition to accidental incidents such as accidental injuries caused by ship navigation and water pollution, the continuous decrease in the number of finless porpoises is ultimately caused by insufficient food resources.

　　Deji plaza subscribed for 1 million fry to demonstrate scientific "release"

　　Yesterday morning, at the Virescence Expo Aquatic Release Platform, deji plaza held the activity of "Yangtze River Aquatic Proliferation and Release". One million fry subscribed by deji plaza were all put into the Yangtze River. The Yangzi Evening News reporter learned that this is the first proliferation and release activity initiated by social forces in China for the protection of finless porpoises. Deji plaza made a scientific demonstration under the guidance of Nanjing Fishery Administration and Fishing Port Supervision and Management Office and Nanjing finless porpoise Protection Association.

　　The so-called "proliferation and release" is the activity of releasing aquatic species or their parents into public waters such as oceans, rivers and lakes by artificial means. Proliferation and release can replenish and restore the population of biological resources, improve the population structure of organisms, and help maintain biodiversity and protect endangered species. According to statistics, in the past three years, Jiangsu has invested 230 million yuan in proliferation and release. In 2015, the province invested more than 79 million yuan, releasing more than 2.1 billion species, including 815 million marine economic species, 1.281 billion inland economic species and 8.48 million rare and endangered species.

　　The subscription of Deji this time includes the fry of four major fishes in the Yangtze River (black carp, grass carp, silver carp and bighead carp) and the national second-class protected wild animal Myxocyprinus asiaticus. The Yangzi Evening News reporter saw at the scene that the fry were transported to the scene by special transport vehicles from the cultivation base cooked in Jiangning Lake. According to the breeder, these fry were specially bred for this proliferation and release, and cold oxygen transportation was used on the way to fully ensure their survival rate. Under the guidance of the staff of Nanjing Fishery Administration and Fishing Port Supervision and Management Office, the volunteers from deji plaza carefully dumped the fry, and along the long discharge embankment, countless fry swam across the slope and merged into the waves by the river. Fish fry are like countless black lines. As soon as they touch the water, they instantly swim away and go to the middle reaches of the river.

　　The release activity was sponsored by deji plaza and Nanjing finless porpoise protection association. Jia Wei, deputy general manager of deji plaza, introduced the original intention of choosing the theme of "Saving Endangered Animals" on the occasion of the 10th anniversary. "The Yangtze finless porpoise is one of the closest endangered animals to us. We hope that through the release of the Yangtze River and the efforts of all sectors of society, more people will pay attention to the living conditions and protect the finless porpoise. To contribute to the protection of the Yangtze finless porpoise, improve the water quality of the Yangtze River and protect the biodiversity of the mother river. " Jia Wei said.

　　Professor Yang Guang told reporters that finless porpoises mainly eat all kinds of fish in the Yangtze River, and they have no choice about the types of fish they eat, mainly depending on their size. "You don’t see it has teeth, but its teeth can only bite, not like people’s teeth have the ability to chew, so it eats fish, and generally fish within 20 cm can be eaten. "Therefore, the fry released this time, on the one hand, are four local fish, which enriches the fishery resources of the Yangtze River, on the other hand, it is also very suitable for finless porpoises to eat."

　　So which fish or aquatic animals are suitable for release? At the scene, the fishery department also listed a list. Freshwater fish include: herring, grass carp, silver carp, bighead carp, bream, Eriocheir sinensis, fugu obscurus and other indigenous species with regional characteristics; Marine fish include: Pseudosciaena crocea, jellyfish, Cynoglossus semilaevis, swimming crab, prawn, Sole Sole, Meretrix meretrix, Sparus macrocephalus, etc. Rare and endangered aquatic animals: Chinese sturgeon, mullet, etc.

　　Expert reminder > >

　　Don’t throw these creatures into the Yangtze River again.

　　"When volunteers of our association patrol the river, they often see citizens who spontaneously organize release activities in the river or along the Yangtze River." Jiang Meng told the Yangzi Evening News reporter that because the public does not know much about species knowledge, in many cases, the released species can not only improve the ecology and enrich fishery resources, but also cause damage. He listed the three most common creatures that were released by the people.

　　Crocodile turtle: It is huge, up to 70 cm long. In the folk concept, releasing such a large turtle is a matter of "accumulating merits" and is favored by domestic enthusiasts. But in fact, the snapping turtle has nothing to do with compassion. It is extremely aggressive and has few natural enemies except alligators. "The most important thing is that the snapping turtle originated in the southeastern United States. If it is put into the Yangtze River, it will become a veritable intruder. Once it enters the Yangtze River, it will become a’ overlord’ and will take away the already scarce food source of the finless porpoise." Jiang Meng said.

　　Snakehead: It is what we often call "mullet". Unlike snapping turtles, snakehead is a common local fish, which is distributed in all major river systems in China. It is also a delicious food on the table of the citizens and can be easily bought in the food market. "But what people often overlook is that snakehead is fierce, fertile and has a huge appetite, and can often eat all other fish in a lake or pond." Jiang Meng told reporters that because finless porpoises are at a disadvantage in quantity, they are unable to compete with snakehead, the "king of big stomachs", for limited bait resources.

　　Brazilian tortoise: The most widely reared reptile in the world, but it is also listed as one of the most dangerous invasive species in the world because it plunders a lot of living resources. In China, many pet markets can see Brazilian tortoises on sale. Jiang Meng appealed that if citizens keep Brazilian tortoises for viewing, they should not be released into the wild or in the river. "Once they reach a brand-new ecological environment without a sufficient number of natural enemies, they will become a scourge and become an ecological disaster there." Jiang Meng said.

　　Nanjing will launch the first "census" of finless porpoises this summer.

　　At present, how many finless porpoises are there in Nanjing section of the Yangtze River? The statistics of the fishery administration department are "twenty or thirty", but there is no more accurate standard answer. Liu Jun, deputy director of Nanjing Fishery and Fishing Port Supervision and Management Office, told Yangzi Evening News reporter at the site of the proliferation and release activities held in deji plaza yesterday that this summer, the fishery administration department will launch the first "population census" of the Yangtze River finless porpoise in Nanjing, the top university in the United Nations for finless porpoise protection.

　　The Yangzi Evening News reporter learned that the latest data about the Yangtze finless porpoise still comes from the 2012 Yangtze River Freshwater Dolphin Investigation Report. At that time, the population of Yangtze finless porpoises was about 1040, less than half of that before 2006, less than that of giant pandas, and showed an accelerated downward trend. However, the details about the finless porpoise in Nanjing section are still vague. Liu Jun introduced that in this survey, besides finding out the latest accurate data, we should also find out the "destructive factors" that affect the normal reproduction of finless porpoises, so as to provide scientific basis for future artificial protection. "The special funds for the current investigation have been approved and will be launched after the parties are properly prepared."

　　Professor Yang Guang from Nanjing Normal University introduced that on October 9, 2014, Nanjing Yangtze finless porpoise nature reserve was established, covering 90% of the waters of Nanjing Yangtze River. He believes that it is essential to further strengthen the protection of Nanjing finless porpoise population and conduct a systematic scientific investigation. "The original data of 20 to 30 finless porpoises are very vague. As a provincial protected area, how many finless porpoises are there in this place, what are the activities of finless porpoises, and what changes have been made in the range of activities in spring and summer? Mastering some basic information of finless porpoises is the premise for us to effectively protect finless porpoises."

　　Expert opinion > >

　　Nanjing should also establish a "finless porpoise protection base"

　　The finless porpoise is the flagship species of the Yangtze River ecosystem, and it is also an indicator species of biodiversity and ecosystem health in the Yangtze River. The survival crisis of the finless porpoise itself is like a wake-up call, warning the deterioration of the entire Yangtze River ecosystem. Professor Yang Guang believes that from the perspective of long-term protection of finless porpoises, Nanjing should refer to the model of "giant panda breeding base" and establish a "finless porpoise protection base". "Since there is such a finless porpoise population in Nanjing, if we want to better carry out protection and rescue work, we can consider establishing a finless porpoise protection center. At the beginning, we can use the resources and facilities of the underwater world to help the finless porpoise, but in the future, we need to set up a special finless porpoise protection center. " Professor Yang said that after the investigation, with scientific consideration and demonstration, the finless porpoise can be better protected through protection, rescue and artificial breeding.

　　Deji celebrates its 10th anniversary.

　　Give the stage to the endangered animals around you

　　Jia Wei, deputy general manager of deji plaza, introduced that deji plaza will celebrate its 10th anniversary on June 26th this year. As a shopping center with humanistic care, deji plaza takes "saving endangered animals" as its theme, hoping to arouse Nanjing citizens’ concern for the environment. Yangzi Evening News reporter learned that in addition to subscribing for breeding, breeding and releasing, around the 10th anniversary, deji plaza also held a series of themed activities to protect finless porpoises and endangered animals.

　　The largest finless porpoise sculpture in Nanjing was exhibited on the first floor of deji plaza.

　　The 10th anniversary of deji plaza, with the theme of "Saving Endangered Animals", presented a series of themed activities. Among them, the artistic sculpture of finless porpoise named "Watch and Smile" is the most thought-provoking. The finless porpoise in the sculpture is smiling, but there are sad tears in his eyes. In the list of "Saving Endangered Animals" in the 10th anniversary of deji plaza, the Yangtze finless porpoise is an endangered animal living around us. This finless porpoise sculpture art exhibition is also to arouse more people’s awareness of caring for and protecting finless porpoises through more shocking art forms.

　　The overall size of the work is 10 meters ×3.8 meters, which is nearly seven times the size of the real finless porpoise, showing its process from beginning to end, from real to virtual until it disappears, just like a sketch drawn by a pen that is about to break ink, and finally disappears into a line. After the neck of the finless porpoise, there are a lot of mottled plastic marks, just like the wounds on the finless porpoise, which are shocking; The rising tail is made of more than 2,000 meters of steel bars, which gradually becomes sparse backwards until the lines disappear in the air, symbolizing the process of the disappearance and extinction of the finless porpoise.

　　On the 10th anniversary of deji plaza, the joint artists jointly presented the artistic sculpture of "Watching and Smiling" finless porpoise, which showed the status quo of the gradual disappearance of "smiling angel" finless porpoise with powerful artistic expression. Deji plaza said that through such soul-shaking works of art and theme activities, he hoped that more people could reflect on their indifference to nature and life, and called on more people to cry out from the bottom of their hearts: protect these "angels" who bring smiles to the world, coexist with every equal life and share the warmth from this world.

　　The "Noah’s Ark" came to Deji Outdoor Square to show all kinds of endangered animals.

　　At the same time, a huge boat-shaped device-"Noah’s Ark" also appeared in deji plaza Outdoor Square. This huge "Noah’s Ark" covers an area of about 600 square meters and has a double hull structure, with a total length of about 40 meters, a width of about 18 meters and a height of about 8 meters. In terms of material application, the hull uses a lot of wood grain plates, which truly restores the effect of wood grain hull and people’s original modeling imagination of Noah’s Ark. There are more than 1100 meters of steel and more than 1800 square meters of wood in the cabin, which makes it more in line with the hull structure and more integrated.

　　"Ark" has a video viewing and experience space of 150 square meters.

Tan Dun

Tan Dun won the 73rd Academy Award for Best Composition.

Tan Dun directed the Song Mountain Music Festival "Zen Shaolin" in China

　　What kind of music will the world hear at the 2008 Beijing Olympic Games? Is it rock music that stirs Guo Jingjing’s diving sound, Yao Ming’s dribbling sound and Liu Xiang’s starting rhythm? Or the Shaolin Zen music of Zhong Mingshan Forest and Crouching Tiger, Hidden Dragon? Or the mysterious music of a village tribe in China?

　　Tan Dun, an international musician who is famous for his innovation, always blends rich oriental charm with western pop elements.

　　This background undoubtedly made him a popular music planner for the opening ceremony of the Beijing 2008 Olympic Games. Recently, our reporter interviewed Tan Dun, who has just successfully completed the planning and creation of "Zen Shaolin Music Grand Ceremony", by email, hoping to give you an answer.

　　Tan Dun Music Creativity

　　How romantic it is to make music with the voice of athletes’ bodies. I have been touched myself, and I can also touch everyone in the world.

　　Bidding: Do you do physical exercise after work? What’s your favorite sport? Who is your favorite athlete?

　　Tan Dun: I insist on swimming every day after work, which is why I always try to have a swimming pool in my hotel when I am on a world tour. I like to brew melodies while swimming, so I often swim for half an hour without knowing it. Conceiving in water makes me feel immersed in the source of inspiration, because water is a symbol of hope and regeneration.

　　My favorite athletes are Guo Jingjing, Yao Ming and Liu Xiang. In my mind, all three of them are musicians, because I saw music and heard colors in their sports. The rhythm and intensity of their movements make me feel as if even the earth can be shocked and reversed. I’m doing research in this field recently, and I plan to turn Guo Jingjing’s diving sound, Yao Ming’s racket sound and Liu Xiang’s starting rhythm into rock music. I hope I can turn the athletes’ hard work and unparalleled shock into a very poetic music, which is the voice of their bodies and the rhythm of their hearts. How romantic it is to make music with their body sounds. I have been touched myself and I can touch everyone in the world.

　　Tan Dun Olympic Dream

　　I dream that Beijing Olympic Games is a world full of poetry, romance and love.

　　Competitive bidding: I heard that recently, IOC President Rogge watched the "Zen Shaolin Music Festival" created and planned by you at the Shaolin Temple in Songshan, the birthplace of Zen, and he excitedly raised your hands and said to all the audience and the media, "It’s so beautiful, this program deserves an Olympic gold medal! Composer Tan Dun should win the Olympic champion! " Is it true?/You don’t say.

　　Tan Dun: It’s true. We were all very excited at that time. This is the IOC’s great appreciation of Wushu and the traditional culture of China-Zen philosophy. Since I wrote Crouching Tiger, Hidden Dragon, I have been continuing my feelings, trying to bring China traditional sports-Wushu to a poetic and romantic realm through music. I dream that the Olympic Games in Beijing is also a world full of poetry, romance and love.

　　Tan Dun’s "Root" of Creation

　　Only new "creativity" can connect the contemporary world with the future China.

　　Competition: You once said that you hoped that orchestras all over the world could play your works to promote China culture and make China culture a big step forward in the 21st century. Is this an important part of your musical ideal?

　　Tan Dun: Yes.

　　My music is in sync with the world, which challenges my creation, and I must also try my best to bring surprises to the world. Can you imagine growing tea and making a tea ceremony in the desert? I just staged my new opera Tea in the desert of New Mexico. It’s so Zen. Everyone was drunk by China in the desert. I’m trying to attract a jade, which requires all art institutions at home and abroad to pay attention to the recognition of "China’s creative culture" and let the whole world know more about Chinese, so that we can have a dialogue with the world. Creativity is a bridge, and only new creativity can connect the contemporary world with the future China. Only in this way can people love a modern China.

　　Competitive newspaper: You said that China is the "root" of your creation. Is this an important reason why your music is widely praised in the world?

　　Tan Dun: This year, my new concept of "Organic Music and Green Rhythm" will be invited to tour 17 countries. The more praise the world gives me, the more I appreciate China culture. I feel that instead of praising me, I should be grateful for this magical land behind me. It is this fertile soil that gave me a golden key, which opened the doors of the metropolitan opera, the Vienna "Golden Music" Hall and the Berlin Philharmonic, the most famous art halls in the world. I believe that we can also use this "golden key" to open the holy door of the Olympic Games.

　　In your opinion, how will the opportunity of hosting the Olympic Games in Beijing promote the spread and promotion of China culture in the world?

　　Tan Dun: As I said, I have a golden key in my hand, which is a magic key made of special materials. It contains China’s profound philosophy, intelligent tradition and creative people, and I am proud to be a member of this group of people. As long as we never forget to excavate and inherit our traditional culture, we will always get inspiration and harvest from it. We must not neglect our own value, because this is precisely the reason why the whole world respects China, and it is also the capital for us to host the Olympic Games and participate in the Olympic culture.

　　Tan Dun Olympic Songs

　　A successful Olympic song, first of all, should be "mind-wandering", which is my advice to all Olympic song creators.

　　Bidding: Beijing is collecting Olympic songs. Is there an Olympic song that impresses you now? What advice do you have for the creators of the songs? What characteristics do you think a successful work should have?

　　Tan Dun: To be a successful Olympic song, we must first "take the heart" and be able to sing the heartfelt desire and passion. This is also my advice to all Olympic song creators (including myself). In addition to "mind-wandering", we should also "be innovative" and innovate a new skill, new structure and new language, pointing directly at people’s spiritual world. We should be international, ethnic and have the courage to innovate.

　　Bidding: Do you have any plans to create theme songs or other musical works for Beijing 2008 Olympic Games?

　　Tan Dun: Like all my colleagues who participated in the creation, I have exhausted my mind in the creation of Olympic music. Before that, I specially went to some cradles of China traditional culture to collect folk songs. The resources there inspired me. There, I heard the world’s expectations for China culture. Olympic songs are hymns written by God through our hands. This is the voice from heaven and the dream of harmony between heaven and earth.

　　Tan Dun Olympic Fate

　　I am an Olympic volunteer, and I hope I can provide my knowledge and experience in music creation without reservation.

　　Bidding: Please tell us about the cultural and promotional activities related to the Beijing Olympic Games in the past.

　　Tan Dun: I have always had a relationship with the Olympic Games. Seven years ago, I participated in the music creation of China’s Olympic bid film. When it was announced in Moscow that China had won the right to host the Olympic Games, I felt honored, because my music also played a small role in China’s successful bid for the Olympic Games. I feel that I have studied music all my life. If I can participate in this once-in-a-century activity, it is our fate, and it is my fate with China culture.

　　Competitive bidding: What other Olympic-related work will you do now or in the coming year? In what way will you participate in the Beijing Olympic Games?

In my work, I have been looking for inspiration from eastern and western cultures, and at the same time, with the help of my friends all over the world, I have attracted these "world leaders" to this sacred work. Apart from composing theme songs, I am also planning some other Olympic-related music, such as Olympic logo music and award music. This is a huge echelon project, in which everyone is silently contributing. I am an Olympic volunteer. I hope I can provide my knowledge and experience in music creation without reservation. I hope our small contribution can contribute to the success of the Olympic Games. I am very proud of being a volunteer of the Olympic Games.

　　Tan Dun Beijing Impression

　　During the Olympic Games, Beijing should have fresh air, cool breeze and unparalleled enthusiasm.

　　Competitive newspaper: Do you feel that the Olympic Games have brought changes to Beijing? What do you think of this change?

　　Tan Dun: This is a rare opportunity in a century. With this opportunity, we will work harder to change the living environment and realize our green dream. It is indeed a very difficult task to make our sky bluer and our water cleaner, so that our future generations can live in a better environment. However, hosting the Olympic Games has greatly touched us, and people should take improving the environment as a top priority by supporting the Olympic Games. Our efforts now will be the greatest wealth for the future.

　　Bidding: What do you think Beijing is like during the Olympic Games?

　　Tan Dun: At that time, Beijing should have fresh air, cool breeze and unparalleled enthusiasm. The whole city was full of love, and the whole world was intoxicated and crazy about it. (Source: Competitive Newspaper)

On December 4, four law professors were sworn in at the public hearing/Xinhua News Agency

　　The Judiciary Committee of the US House of Representatives held its first hearing on the impeachment investigation of President Donald Trump on the 4th. Some legal experts have determined that Trump’s contacts with Ukraine conform to the definition of "misdemeanor or felony" that can be impeached in the US Constitution.

　　In addition, the US federal prosecutor recently interviewed Andrei KoBorev, CEO of Ukrainian oil and gas company, to investigate the business transactions between President Donald Trump’s personal lawyer Rudy Giuliani and his partners.

　　Is the president’s action unconstitutional?

　　On the same day, the Judiciary Committee of the House of Representatives "took over" the impeachment investigation hearing of the Intelligence Committee and listened to legal experts’ opinions on the constitutional basis of impeachment. At the public hearing, four law professors were invited to testify on the constitutional basis of impeaching the president. At the hearing, the positions of the democratic and Republican parties were seriously opposed. Jerry Nadler, chairman of the House Judiciary Committee and a Democrat, said at the hearing that Trump "directly and explicitly sought foreign intervention in American elections" when dealing with Ukrainian affairs, which was unconstitutional. Three law professors invited by the Democratic Party all said that Trump was suspected of abusing his power and obstructing justice, and his behavior had met the conditions for impeachment. This Committee will then hold more hearings to decide whether to propose to impeach Trump and what "charges" to impeach.

　　Pamela Karan, a professor at Stanford Law School in the United States who attended the hearing, said that Trump "encouraged" Ukrainian President Vladimir Zelensky to investigate Joe Biden, a former vice president of the United States and a democratic candidate for the 2020 presidential election, and his son Hunter’s actions were "serious abuse of power".

　　Some experts hold the opposite opinion. Jonathan Terry, a professor at George Washington University in the United States, opposes the impeachment of Trump and believes that the impeachment investigation lacks sufficient evidence to support it and will end in vain.

　　The impeachment investigation began in September because an intelligence official accused Trump of using military aid as a bargaining chip when he spoke to Zelensky on the phone in July, and asked Uzbekistan to investigate and collect the "black materials" of Biden and his son. The Democratic Party accused the Republican president of abusing his power, seeking foreign forces to interfere in next year’s presidential election and harming national security interests, and then launched an impeachment investigation in the dominant House of Representatives. The previous investigation was led by the House Intelligence Committee, and several closed-door and public hearings were held. Trump decided that he was "politically persecuted" by Democrats, and his dissatisfied lawyer could not ask witnesses at the hearing.

　　Aides of some Democratic lawmakers disclosed that the Judiciary Committee may vote on whether to propose to impeach Trump in the next two weeks. Once passed, the impeachment case may be voted in the plenary session of the House of Representatives before Christmas on December 25th.

　　Trump supports private lawyers

　　On the 4th, Trump reported to the House Intelligence Committee that it was "no big deal" that his personal lawyer, Rudy Giuliani, frequently contacted White House officials by telephone.

　　On the 3rd, the Intelligence Committee published a 300-page impeachment investigation report, which disclosed some telephone call records of Trump’s "people around him", suggesting that inappropriate behavior was not limited to Trump himself. According to the report, these phone records involved many calls between Giuliani, Giuliani’s partner, Devon nunes, the highest-ranking Republican on the House Intelligence Committee, and the White House Office of Management and Budget.

　　"Some people say that he (Giuliani) called the White House. What does it matter? " Trump told reporters when attending the North Atlantic Treaty Organization summit in London, England, "Is that supposed to be a big deal? I don’t think so. "

　　William Taylor, the U.S. Chargé d ‘affaires in Ukraine, testified before the Intelligence Committee last month that the U.S. government pushed Ukraine to investigate Biden and his son through "unconventional policy channels", which was led by Giuliani. According to the 300-page report, Giuliani called a telephone number associated with the White House Office of Management and Budget three times on April 24, and it was this institution that once frozen military assistance to Ukraine; He also called a phone number associated with the White House eight times that day. Coincidentally, that night, the State Council called Mary Jovanovic, then the US ambassador to Ukraine, and asked her to return to China because the White House officials were "worried".

　　Trump insisted that he knew nothing about those calls, and insisted that Giuliani was a "very good lawyer" and "the best mayor in new york’s history". Giuliani argued that his repeated phone calls with the White House did not constitute a "specific topic". "You know, I am the president’s lawyer".

　　According to the procedure, if the House of Representatives approves the impeachment, the Senate will "hear" the impeachment case and decide whether to "convict" and dismiss Trump. However, the Senate is controlled by Trump’s Republican Party.

　　The oil tycoon volunteered to interview the prosecutor.

　　On the 4th, Associated Press quoted Lanny Brewer, lawyer of Andrei KoBorev, CEO of Ukrainian oil and gas company, as saying that KoBorev voluntarily met with representatives of the US Department of Justice. "The Ministry of Justice requested an interview with Andrei Coe Borev," Brewer said. "He agreed and took the initiative to talk to the prosecutor." Brewer did not specify the time and place of the interview. A source who was not authorized to talk about the investigation said that Coe Borev met with the US prosecutor in the British capital London.

　　A number of unnamed sources said that federal prosecutors in new york are investigating Giuliani’s business transactions. Previously, his partners, Florida businessmen Lev panas and Igor Fruhmann, were arrested while preparing to board a plane for Europe with a one-way ticket from Washington.

　　According to the indictment, panas and Fruhmann are believed to be the key intermediaries who helped Giuliani push the Ukrainian investigation into Joe Biden, a former vice president of the United States and a democratic candidate for next year’s presidential election, and his son Hunter. In January this year, they not only arranged for Giuliani to meet with yuriy lutsenko, the then Ukrainian Supreme Prosecutor, in new york, but also arranged for Giuliani to meet with other Ukrainian government officials many times.

　　The Associated Press reported that the impeachment investigation in the House of Representatives focused more on Giuliani’s role in pushing Uzbekistan to investigate Biden and his son. In contrast, the federal prosecutor’s "interview" with Borev and other Ukrainian oil and gas company executives showed that their investigation had expanded to the commercial transaction level of Giuliani and his partners.

　　William Taylor, the U.S. Chargé d ‘affaires in Ukraine, testified before the Intelligence Committee of the House of Representatives last month that the U.S. government pushed Ukraine to investigate Biden and his son through "unconventional policy channels", which was led by Giuliani.

Cctv newsOn the morning of June 8, the State Council Office held a press conference on "Implementing the Party’s 20 Major Decisions and Deploying and Promoting the Modernization of Emergency Management System and Capacity". Min Yiren, director of the Seismological Bureau of China, introduced at the meeting that at present, the national earthquake intensity quick report and early warning project has completed the main construction task, and 15,391 earthquake early warning stations, 3 national centers, 31 provincial centers and 173 prefecture-level information release centers have been built, forming a China earthquake early warning network composed of five systems: station observation, data processing, information service, communication network and technical support, and carrying out pilot services in Beijing, Tianjin and Hebei, Sichuan, Yunnan and Fujian. It is expected to be completed and accepted by the end of this year. After the project is put into operation, it will play a role in disaster reduction in the following aspects:

The first is to build a "first line of defense" for earthquake relief and reduce earthquake casualties. After the devastating earthquake, China Earthquake Early Warning Network will release earthquake early warning information through various channels such as emergency broadcast, mobile phone, TV, special terminal, etc., so as to provide users in the target area with early warning time of several seconds to dozens of seconds for emergency avoidance; After the earthquake, the distribution of the hardest hit areas can be quickly judged by measuring the measured earthquake intensity in a few minutes, which provides a scientific basis for the decision-making and deployment of earthquake relief. 6.2 seconds after the Luding M6.8 earthquake in Sichuan Province on September 5, 2022, China Earthquake Early Warning Network successfully released the early warning information, realizing the second-level early warning coverage for 1.5 million people in the epicenter and its surrounding areas.

The second is to "escort" lifeline projects and emergency disposal of major infrastructure. Relying on earthquake early warning terminals, emergency broadcasting and special communication lines, we will provide earthquake early warning information for the automatic emergency response of major strategic infrastructure such as high-speed railways, nuclear power plants, oil and gas pipelines and Gaoba reservoirs, and people’s livelihood infrastructure such as high-rise buildings, underground facilities and large-scale complexes, fill the gap in cross-industry earthquake emergency response services, promote the expansion of earthquake monitoring to earthquake disaster risk monitoring and prevention, and strengthen the ability of earthquake prevention and disaster reduction in the whole society.

The third is to provide strong support for earth science progress and international disaster reduction cooperation. Give full play to the advantages of building the world’s largest real-time transmission earthquake monitoring station network, provide high-quality scientific data information for promoting the innovative development of real-time seismology, real-time disaster science and earthquake engineering, and help the development and progress of earth science. At present, China’s earthquake early warning technology has gone abroad and been applied to the construction of Indonesian Jakarta-Bandung High-speed Railway. Seismological Bureau of China will give full play to its professional and technical advantages, better serve the country’s overall diplomacy, strengthen international cooperation in earthquake prevention and disaster reduction, and work together to reduce the risk of earthquake disasters.

In the next step, Seismological Bureau of China will continue to improve the construction of earthquake early warning network in China, continuously improve the safety, reliability and standardization of earthquake early warning service, expand the service field and efficiency, and provide more powerful earthquake safety guarantee for high-quality economic and social development.
