The second international cooperative scientific research team for Qinghai Tibet scientific research investigates the evolution process of the the Yarlung Zangbo River | Research | Scientific research team
CCTV news: From June 20 to 29, a scientific expedition team of the second Tibetan scientific expedition "Source sink process and evolution of solid materials in the river system", which was composed of several top international scientists, came to the Tibetan Xigaze section in the west of the Yarlung Zangbo River to investigate the geological evolution, geomorphology, ecology and environmental evolution of relevant river valley regions, aiming to focus on the important scientific issue of the evolution of the the Yarlung Zangbo River River and changes in the ecological environment of its basin.
The the Yarlung Zangbo River is one of the largest rivers in the world at the highest altitude. Its source is the Gema Yangzong Glacier in Zhongba County, Shigatse City. In the Shigatse section of the the Yarlung Zangbo River, the international cooperation scientific team made a 9-day visit to the typical areas of the the Yarlung Zangbo River suture zone, the Shigatse fore arc basin, and the valley dune landform. They carried out investigations on the types of rock genesis, sedimentary environment analysis, river sediment transport processes, etc., reached many important consensus on the geological evolution history of the southern Qinghai Tibet Plateau, and pointed out that the formation and evolution of the the Yarlung Zangbo River are closely related to the geological evolution since the Cenozoic collision between India and Eurasia.
Wang Chengshan, an academician of the CAS Member and a professor of China University of Geosciences: We have a preliminary understanding that the desertification problem of the the Yarlung Zangbo River may be caused by the evolution of the entire valley and the factors of glacier melting and superposition, which is our preliminary result.
In addition, foreign experts also visited Xizang to learn about its economic, social and technological development. They look forward to further deepening cooperation with Chinese scientists in the evolution of the Qinghai Tibet Plateau and ecological environment protection, contributing to global scientific and technological progress and regional sustainable development.
Irina, academician of the European Academy of Sciences, President of the European Federation of Geosciences: I am very honored to come to Tibet to participate in this investigation. This allows me to see China and Tibet from a new perspective, so it left a very unique impression on me. At the same time, it also provides a new perspective for future earth science cooperation.
