Located in the northeastern part of the Qinghai-Tibet Plateau, the Qinghai Lake is key to maintaining the ecological balance in western China. It is also a natural barrier for controlling the eastward spread of desertification and ensuring the safety of agricultural areas in eastern China.

In recent years, with various ecological projects carried out in the Qinghai Lake, the environment here has been greatly improved.
