Qinghai Lake is China's largest inland plateau saltwater lake. It is an important body of water that maintains ecological security in the northeastern part of the Qinghai-Tibet Plateau. It is also a natural barrier to control the eastward spread of desertification in the west.
The characteristics and evolution of the ecological environment of Qinghai Lake reflect to a large extent the change trend of the overall ecological environment of the Qinghai-Tibet Plateau, which has a greater impact on the Qaidam Basin, Sanjiangyuan, Qilian Mountains and other areas.
