In 2022, Jiangyuan Scientific Examination launched the focus on "ice and carbon"

Xinhua News Agency, Xining, July 24th (Reporter Chen Jie and Tanaka Quan) In the 2022, Jiangyuan Comprehensive Scientific Investigation was launched on the 24th in Yushu Tibetan Autonomous Prefecture, Qinghai Province. This scientific examination activity will conduct a designated "physical examination" for the Yangtze River source and Lancang River area. Among them, the observation of ice reserves and wetland carbon reserves is the focus of this scientific examination.

In 2022, the Jiangyuan Comprehensive Scientific Examination was led by the Yangtze River Conservatory of the Yangtze River Sciences of the Yangtze River Water Conservancy Commissioner, and cooperated with the Qinghai Provincial Department of Water Resources, the Yangtze River Technology and Economics Society, and the Yangtze River Civilization Museum to the Zhengyuan River, Nanyuan Dangqu, and Beiyuan Chumarol in the Yangtze River. The water resources and water ecological environment of the river and Lancang River have carried out scientific investigations. The inspection content includes glaciers, river hydrology, sediment, river river potential, water environment, water ecology, water resources, water and soil loss, frozen soil, terrain and localforms.

Glacier inspection is one of the key contents of this scientific examination. Based on the early remote sensing monitoring, this scientific examination will detect the thickness of the glacier through technical such as the land radar to calculate the ice reserves. This will provide basic research materials for predicting the changes in the future rivers.

This scientific examination will also focus on the carbon reserves of the Yangtze River Source Wetland. The scientific examination team will conduct this background investigation of wetland waters, vegetation and soil carbon reserves through pile sampling and other methods to lay the foundation for wetland carbon exchange research.

As an important part of the Qinghai -Tibet Plateau ecosystem, the area of ​​the Yangtze River and Lancang River is a sensitive response area and a fragile area for climate change. Essence

Xu Ping, chief engineer of the Yangtze River Academy of Sciences of the Yangtze River Water Conservancy Commissioner, introduced that this investigation will further grasp the current status of the ecological environment of the Yangtze River and Lancang River area, for the protection of the Yangtze River, the construction of the Sanjiangyuan National Park, the Yangtze River source and the Lancangjiangyuan District "Water -Ecology - The environment "evolution and adaptive protection countermeasures provides basic data.
