Qinghai Lake, located in northwest China's Qinghai Province, is China's largest inland saltwater lake. It is a major transit point for migratory birds from Central Asia to India and East Asia to Australia. It also serves as an important winter home for waterbirds on the Qinghai-Tibet Plateau.
Qinghai Lake is a crucial body of water to maintain ecological security in the northeastern Qinghai-Tibet Plateau. It is also a natural barrier for controlling the eastward spread of desertification. The improving ecosystem of the lake in recent years has benefited a variety of plant and animal species.
