An analysis is made about the response of Selin Co lake area change to climate change, based on RS, GIS and modern climate statistical methods with the aid of TM and CBERS remote sensing data from 1980-2008 as well as temperature, precipitation, the amount of evaporation, the biggest depth of frozen soil from 1975-2008 at the stations such as Shenzha, Bange and Anduo etc. Based on the digitized 1:100,000 topographic map in 1975 and through analyses of remote sensing data after the 1980s, it is found that water levels of Selin Co, Co'e and Yagen Co lakes present a distinct expanding trend in the past 30 years. In 2008, the water level areas of the above three lakes are 2196.23 km2, 279.24 km2, 103.07 km2, and they increase by 574.46 km2, 11.59 km2 and 68.13 km2 respectively compared to 1975. Moreover, Selin Co expands at a rate of 20%, with an average of 420 km2/10a, thus it has become the largest salty inland lake, exceeding the area of Nam Co lake in Tibet during the period 1999-2008. The main reasons for lake area expansion is the increase in snow/ice meting water under the background of global warming, followed by the increase of precipitation, decrease of the evaporation and degradation of permafrost.
Key words： change of water level; climate change; Tibet; Selin Co (lake)
