Explore the series of research results of geological evolution and high -cold civilization for the second Qinghai -Tibet Science Examination

The growth and desertification of the northeast edge of the Qinghai -Tibet Plateau, the development of human beings on the plateau and the development of high -cold civilizations, and human beings who have gone out of Qinghai -Tibet and the human conquest plateau, the geopolitical interaction behavior of the Qinghai -Tibet Plateau ethnic group over the past 2000 ...

The reporter learned from the second Qinghai -Tibet Science Examination "Geological Evidence and Human Adaptive" on the 8th of the 8th. A series of breakthroughs and achievements have been achieved in the fields of high -level geological evolution and high -cold civilization.

How do humans go to the plateau step by step? What are the stages of the development of high -cold civilization?

Academician Chen Figu, director of the Qinghai -Tibet Plateau Institute of the Chinese Academy of Sciences, led the team to investigate and explore the archeological site of the Qinghai -Tibet Plateau, as well as the analysis of lake deposits and historical documents.

The five stages have been: the ancient Homo sapiens have adapted to the plateau from the end of the world; the modern Homo sapiens opened the exploration of the plateau hinterland 40,000 to 30,000 years ago; During the warmth period, the crowds of fine stone spreads to the plateau in a large range; the Againan agricultural crowd entered the low altitude valley area of ​​the east of the plateau 5200 years ago, and began to settle in 3,000 meters above the altitude area of ​​3000 meters in the east of the plateau before 4800. The development of the pastoral economy helps the population to settle on a large -scale high -altitude area.

At the same time, Professor Song Changqing, Minister of Geographical Sciences of Beijing Normal University, found that in the past 2000, the Qinghai -Tibet Plateau ethnic groups and the geopolitical interaction of the eastern ethnic groups in the eastern ethnic group were associated with the changes in the climate and environment. In-depth analysis.

What is the process of dragon and environmental evolution of the Qinghai -Tibet Plateau? Zhang Jinjiang, a professor at the School of Earth and Space Sciences of Peking University, focused on the northeast edge of the "Alkin-Qilian-Hexi Corridor", and conducted in-depth research.

Focusing on the key structural sector, the team has reconstructed the distribution map of the ancient lake of the Dunhuang Basin through the characteristics of sedimentary characteristics and the study of the sedimentary age. The desertification process of the northeast of the Qinghai -Tibet Plateau in the late Qinghai -Tibet Plateau.

What impact does the Longsheng of the Qinghai -Tibet Plateau have on the evolution of global animals and plants?中科院古脊椎动物与古人类研究所所长邓涛研究员介绍，科考最新取得的化石证据和研究结果表明，许多哺乳动物、鱼类、鸟类和植物起源于青藏高原，并在不同地质时期向The spread of the world around the world has become an important evolution hub for modern biological diversity.

"The strong rising of the Qinghai -Tibet Plateau in the new generation has profoundly affected the climate environment and ecosystem of the plateau and the edge of the edge, and has a powerful driver to the evolution of creatures." Deng Tao said.

The relevant person in charge of the Ministry of Science and Technology Strategic Planning said that the second Qinghai -Tibet Sciences adhered to the joint research of humanities and natural sciences, attached great importance to the protection and inheritance of cultural heritage, and in -depth investigation of the impact of the formation and continuation of the geographical environment on the formation and continuation of the historical culture, and portrayed the evolution of the rolling ridges of the world. The process re -described the history of the development of high -cold civilization, and explained the evolution pattern of the Chinese nation.
