Buir Lake is a freshwater lake that straddles the border between Mongolia and Chinese Inner Mongolia. It lies within the Buir Lake Depression. The Chinese city of Hulunbuir is named after both this lake and Hulun Lake, which lies entirely on the Chinese side of the border in Inner Mongolia. In 2004, the lake was registered in the Ramsar Convention as an internationally-important marshy place in the world.
Buir Lake is considered as one of the freshest lakes. The lake’s water contains hydrocarbonate, chloride, sodium and calcium, so the lake is classified in family of hydrocarbonate-chloride.
