The second Qinghai -Tibet Science and Tibet Science Examination Disaster Prevention and Substance Academic Exchange Conference was held in Chengdu in Chengdu

On July 15th, the second Qinghai -Tibet Science and Technology Examination Disaster and Subject Academic Exchange Association hosted by the Ministry of Science and Technology and the Chinese Academy of Sciences was held in Chengdu.

At the exchange meeting, the participating experts introduced the situation and preliminary research results of the Qinghai -Tibet Plateau natural disasters and disaster prevention and mitigation, the structural characteristics of the depth of the southeast edge of the Qinghai -Tibet Plateau, and its dynamic process.

Cui Peng, an academician of the Chinese Academy of Sciences, pointed out that the first system of the Qinghai -Tibet Plateau scientific examination system found that the Qinghai -Tibet Plateau was found in the Banzhai Plateau, and established and improved the database of the Natural Disaster Database of the Qinghai -Tibet Plateau and prepared a disaster distribution map. This survey also revealed the evolution mechanism of major disasters under the action of internal and external power coupling, and established the theory and method of multi -scale comprehensive disaster risk assessment theory and methods.

In addition, how to recognize the occurrence of disaster weather in the Qinghai -Tibet Plateau, a strong signal of developing a precursor is a key link for the disaster weather forecast warning. Xu Xiangde, an academician of the China Institute of Meteorological Research, introduced the characteristics of the flow of flow of the clouds and precipitation process of the Qinghai -Tibet Plateau and the cause of enriching the water resources, and revealed the response to climate change in the water resources and environment of Asian water towers (such as glacier melting and retreat).

Xu Weilin, an academician of the Chinese Academy of Engineering, introduced the role of floods and sand coupling in detail at the meeting. He mentioned that only the scientific issues faced in the prevention and control of the floods and sand coupling disasters of the mountains and sand coupling. Conditions can solve the cognitive problems of the risk of disaster risks significantly increased and even the dynamic mechanism of the "small water disaster" dynamic mechanism.

Xu Xiwei, a researcher at the National Natural Disaster Prevention Research Institute of the Emergency Management Department, emphasized that during the second Qinghai -Tibet Plateau scientific research, the scientific research team used drone aviation photography technology, LIDAR technology, and three -dimensional electrical structural detection technology to determine the southeast of the Qinghai -Tibet Plateau. The two different deformation domains such as the near -east -west stretching area, the side squeezing area, and the boundary sliding area of ​​the near -east -west directional stretching area are shortened.

In addition, Niu Fujun, Executive Deputy Director and Researcher of the National Key Laboratory of the Northwest Institute of Environmental Resources of the Chinese Academy of Sciences, pointed out that the scientific test team has fully investigated the frozen soil frozen disaster in the entire area of ​​the Qinghai -Tibet Plateau, paying attention to the development trend of major frozen earth engineering diseases, and in -depth deepening The inspection of the frozen soil environment in the core area of ​​the plateau has realized the census of the heat -fusion disaster in the frozen soil area of ​​the Qinghai -Tibet Plateau for many years, revealing the fact that the Qinghai -Tibet Plateau has been intensified in recent decades.

Zheng Wenjun, a professor at the School of Earth Science and Engineering, Sun Yat -sen University, mentioned that the three groups of activities in different directions and properties of different directions and the activity plots separated by their separators form the latest structural activity images in the northeast of the plateau. The activity directly promoted the birth and occurrence of strong earthquakes in the northeast of the Plateau, and the interaction between the plots (gradually squeezing north and expanding the east limited squeezing) is the peripheral edge of the Payan Kara land in recent years. The main power mechanism of frequency.

After the scientific report meeting, the participating experts made special reports and discussed the technical progress of the Tibet Binghu collapse disaster and prevention and treatment of the prevention and control of geological disasters in Sichuan Province.

It is reported that the "Geological Environment and Disaster" comprehensive scientific research tasks set up by the Second Qinghai -Tibet Plateau Comprehensive Scientific Investigation and Research will help the Qinghai -Tibet Plateau geological environmental protection and ecological construction and ensure life safety.
