New Gansu client Lanzhou News (New Gansu · Gansu Daily reporter Su Jiaying) Recently, the latest research results of the local environmental education evolution of the Ministry of Environmental Education of Lanzhou University and the latest research results of the new generation environment research team showed that the modern Yellow River water system began to be formed in 1.25 million years ago. The acceleration of the global climate transition period of China update has a important impact on it. The results of the study provided a new perspective for studying the evolutionary history of the world and the development of the water system.

The Yellow River is the cradle of Chinese civilization. The formation of the formation of evolutionary history and its driving mechanism of the modern Yellow River system can provide important evidence for how to shape the structure-climatic interaction. It is currently known that the formation of "Ji" and the east of the Sanmenxia Guantong Tongtong is an important symbol for the formation of the modern Yellow River system. However At present, there are still different views on the formation of the formation of the modern Yellow River system, and there are different understanding of the reasons for the formation.

In this regard, under the coordination and deployment of Academician Chen Figue, Professor Wang Xin, Professor Hu Zhenbo, Professor Nie Junsheng, Professor Pan Baotian, and the China Earthquake Administration Geological Research The first monitoring center of the China Earthquake Administration, the University of Shimagen University, and the China University of Geosciences (Wuhan) and other units jointly implemented an environmental drilling and conducting cooperative research at the Sanmenxia Basin Center. Through the comparison with the edge of the basin, the first appearance of the river sediment at 108 meters at the core of the rock core is the oldest imprint left by the Yellow River in the Sanmenxia area.

After a series of studies, since 1.25 million years ago, the sedimentation of the Sanmenxia Basin River began to develop on large-scale development, the debris substances of the upstream Ordos are poured in, and the sedimentary environment has gone through a closed salt water-micro-salt water lake environment A significant change in the open river environment. Comprehensive new development evidence of landform analysis, the research team finally proposed that the modern Yellow River system began formation before 1.25 million years ago, and the acceleration of the global climate transformation period of China Renewal World has a new understanding of the formation of an important impact. The research results were published on August 15th in the authoritative journal Science Bulletin and were selected as the cover article on the 15th of 2022.
