New breakthroughs in Mount Everest of my country

The melting of ice and snow at the peak, the special reactions of human physiology in the Mount Everest area, the synergy and influence of the Western wind-monsoon, and the green process of the green area of ​​Everest ... The "peak mission" of the "peak mission" in Everest scientific research held from July 12 It was learned at the exchange meeting that since the end of April this year, the "Peak Mission" Mount Everest Scientific Examination has continued to make breakthroughs and has produced a series of results in multiple research fields.

The Qinghai -Tibet Plateau is the roof of the world and the Asian water tower, the third pole of the earth, and its climate and environmental changes will have a huge impact on the whole of the world. As an important part of the second Qinghai -Tibet scientific research, the Everest science examination is of great significance.

What is the trend of environmental changes in extremely high altitude areas? Xu Baiqing, the leader of the high altitude ice core drilling group and researcher of the Qinghai -Tibet Plateau Institute of the Chinese Academy of Sciences, introduced that this scientific test was first successfully obtained from 6,500 meters, 7028 meters, and 8848 meters of ice and snow samples. Altitude ice and snow are accelerating and melting; extremely high -altitude environmental changes have significant gradient characteristics; since 1860, Mount Everest has a huge change in monsoon precipitation in the high altitude area, and it has continued to decrease since the 1950s, and human activities The environmental impact is continuously strengthened.

The Qinghai -Tibet Plateau is a giant regulator of monsoon and western wind, which has an important impact on global climate change. The scientific research team carried out the collaborative role of the West wind-monsoon in Everest area at different altitude in Everest Base Camp and Mount Everest Station and its impact on the intensive exploration test.

"Preliminary analysis found that the Zhufeng base camp has a very strong glacier wind, and the effects of attracting the surrounding atmosphere caused by the strong thermal effects of the northern slope of Mount Everest are the main driving force of strong wind in this area during the day. In early May, the Western Wind circulation has a significant impact on the Boundary of the Himalayan Mountains. "The collaborative role of the West Wind-monsoon in Everest and its influence of the team leader and researcher Ma Yaoming of the Qinghai-Tibet Plateau Institute of the Chinese Academy of Sciences.

For a long time, due to the lack of observation data of the main greenhouse gas concentration of the plateau atmosphere, related research work lacks sufficient data support. This scientific examination uses the new platform of helicopters and floating boats to measure the vertical distribution of carbon dioxide and methane in the Everest area for the first time. Distribution features.

"The results of this research help to accurately estimate the carbon source function of the Qinghai -Tibet Plateau ecosystem, and provide data support for carbon neutrality and targets." Said Park Shilong, Captain of Mount Everest and researcher at the Qinghai -Tibet Plateau Institute of the Chinese Academy of Sciences.

What kind of physiological reactions will the human body in the Everest area cause? Academician Zhu Tong, Captain of the Human Activity Branch of Mount Everest Scientific Examination, introduced that this scientific test was for the first time to obtain the health data and samples of scientific examinations and mountaineers during different altitude adaptation periods. Further analysis is expected Exposure of the effects of cardiopulmonary health, blood circulation, apparent genetic, protein synthesis modification, metabolic change, immune and physiological function changes such as blood circulation, epigenetics, protein synthesis modification, protein synthesis modification, protein synthesis modification, metabolic change, immune and physiological functional changes.

The output of many achievements is inseparable from a series of breakthroughs obtained by the Everest Examination: my country's Everest Scientific Examination exceeds 8000 meters for the first time at the height of Shanghai to set up the highest altitude meteorological station in the world ... A number of scientific investigations and research records. At the same time, the use of a series of advanced instruments such as "Jimu No. 1" type III floating boat, glacier radar thickness meter, microwave radiation meter, and atmospheric turbulence observation system, which has effectively improved the observation accuracy and detection level.

"'Peak Mission' Evening Scientific Examination has realized the transformation from the mountaineering mountaineering model from the climbing department to the scientific examination climbing model, and the transformation of the climbing idea of" I want to conquer you 'to' I want to know you ' The application of the new method has achieved important international influence. "Academician Yao Tandong, director of the General Commander of Mount Everest and researcher at the Qinghai -Tibet Plateau Institute of the Chinese Academy of Sciences.

"The second Qinghai -Tibet science examination aims at the international frontier and national strategy, carry out cross -disciplinary, cross -domain, and cross -regional collaboration, focusing on key areas, expanding the breadth and depth of scientific research and field inspection The situation of the Qinghai -Tibet Plateau. "Li Meng, deputy minister of the Ministry of Science and Technology, said that in the future, it is necessary to further strengthen the integration of tasks and condense results to serve the construction of the highland of the Qinghai -Tibet Plateau ecological civilization.
