The second Qinghai -Tibet Sciences released a number of ecological security barriers and the results of biological diversity scientific research

Qinghai -Tibet Plateau's biological diversity evolution, ecosystem and ecological security, the origin and evolution of the people of the plateau ... The reporter learned from the Second Qinghai -Tibet Science Examination Academic Exchange Conference held by the Ministry of Science and Technology and the Chinese Academy of Sciences on the 21st that the Qinghai -Tibet Plateau ecological security barrier New breakthroughs in many aspects with biological diversity scientific research.

Deng Tao, director and researcher of the Institute of Ancient Human Research Institute of the Chinese Academy of Sciences and the Ancient Human Research Institute, introduced at the meeting that "the new discovery of the second Qinghai -Tibet science examination has pushed the origin of the alpine crickets for nearly 20 million years, which proves that it is at 3400 at 3400 After thousands of years ago, it appeared in the east of the Qinghai -Tibet Plateau. "Since then, Takayama has spread along the Gangdis Mountains and Himalayas to the west, and its spread to the east and southeast has formed an advantageous population in Hengduan Mountain area. Biological diversity has an important impact.

Yang Yongping, director and researcher of the Chinese Academy of Sciences Xishuangbanna Herbal Botanical Garden, said that the second Qinghai -Tibet Science and Tibetan scientific research found that the climate of the Qinghai -Tibet Plateau continued to "warm and humidize" the area of ​​frozen soil, the decrease in the area of ​​the swamp wetland, and the degradation of some biological habitats, but the ecosystem pattern generally overall Stability, overall quality improvement, and improvement of functions, "Nature protection plays a vital role in the protection of the biological diversity of the Qinghai -Tibet Plateau."

Focusing on how humans settle and adapt to the extreme environment of the plateau, Kong Qingpeng, a researcher at the Institute of Animal Research from the Chinese Academy of Sciences, introduced it from the perspective of archeological and genetic perspectives that ancient humans had moved on the Qinghai -Tibet Plateau at 190,000 to 160,000 years ago; At least 40,000 to 30,000 years ago, set foot in the plateau, and achieved large -scale permanent settlement under the promotion of agricultural technology innovation 3600 years ago. "In the process of human settlement of the plateau, genetic mutations, gene expression, structural mutation, etc. play an important role in the physiological adaptation of the plateau," he said.

The participating experts also exchanged discussions on "the mechanism of soil microorganisms in the context of climate change", "The Diversity and Evolution of amphibious reptiles in the Qinghai -Tibet Plateau and plant diversity", "Qinghai -Tibet Plateau", "Qinghai -Tibet Plateau".

Shi Peng, secretary of the party committee and researcher of the Kunming Institute of Science and Technology of the Chinese Academy of Sciences, said: "The protection of biodiversity should be gradually standardized, refined, and digitized.
