The lake area of the Yangtze River Yuanyuan Park of Sanjiangyuan National Park has increased for 25 consecutive years

Recently, the reporter learned from the Qinghai Provincial Meteorological Bureau that the latest research on the remote sensing monitoring of Yushu Sanjiangyuan Ecological Meteorological Speed ​​Center in Yushu Province shows that from 1990 to 2021, the total area of ​​the lake in the Yangtze River Yuanyuan Park of Sanjiangyuan National Park increased significantly, from 1995 to 2020 for 25 consecutive consecutive consecutive Increased year.

According to data from Sanjiangyuan Ecological Meteorological Sub -Satellite Center satellite remote sensing monitoring research data, from 1990 to 2021, the total area of ​​typical lakes in the Yangtze River Yuanyuan Park increased significantly by 1040.24 square kilometers, an average of 32.11 square kilometers per year. Among them, from 1990 to 1995, the area of ​​lakes decreased. From 1995 to 2020, it increased for 25 consecutive years, and the growth momentum of lake area increased in 2021, a decrease of 16.70 square kilometers from 2020.

The Yangtze River Yuanyuan Park of Sanjiangyuan National Park is located in the hinterland of the Qinghai -Tibet Plateau with an area of ​​90,300 square kilometers. The Yangtze River Yuan Park is based on the Chuma River, Tuoluo River, and Tongtian River Basin as the main framework. As the source of the "water source core area" of Sanjiangyuan and the origin of the "China Water Tower", the total area of ​​the lake in the Yangtze River Yuanyuan occupy about Sanjiangyuan Lake More than half of the total area, the total area of ​​wetland is 23,200 square kilometers, mainly including river wetlands, lake wetlands, swamp wetlands, and inland beaches. There are about 160 lakes greater than 0.5 square kilometers in the park, especially the wetland of high -altitude lake groups is mainly distributed in cocoa Sili. The lake groups not only nourish the growth of plants, but also the "barometer" of changes in the ecological environment of the Qinghai -Tibet Plateau. At the same time, it is also one of the areas of natural wetlands and biological diversity distribution areas in China, as well as one of the areas of biological species formation and evolution. It has ecological functions such as water conservation and regulation, biological diversity protection, and ecological security guarantee in the Yangtze River Basin.

Tan Debao, deputy chief engineer of the Yangtze River Academy of Sciences, said that lake wetland can not only effectively regulate the amount of water and local climate environment of Sanjiang source, but also an important habitat for various creatures. Storage capacity to better protect biodiversity, but at the same time, it will also cause some potential hidden dangers, and continuous attention and in -depth research need to be continued.
