Abstract According to the remote sensing data obtained in 1972,1992 and 1999, it is found that the Selincuo lake has expanded. The area of the lake has expanded from 1707 km2 to 1823 km2. Based on an analysis of such factors as meteorological phenomena, tectonic activity and uplifting of Qinghai-Tibet plateau, this paper explains the reasons for the lake expansion. It seems that the greenhouse effect plays the major role. With the rising of the temperature, the thawing of the glacier and the softening of the frozen earth result in the formation of free water, and then the water flows into the Selincuo Lake, leading to the expansion of the lake.
