Located at the west of the Tianshan Mountains, the southwest of the Junger Basin, Sailimu Lake is the largest alpine lake in Xinjiang with a catchment area of 1 408 km 2 , lake area of 457 km 2 . Its maximum depth reaches to 86 meters, and total water capacity is 210×10 8 m 3 . The altitude of the lake is 2 073 m. Surrounded by high mountains, it is an occluded lake. Since 1980s, there is a warm-wet trend of the climate in Sailimu Lake and its neighboring areas, indicated by increasing of the precipitation and rising of the air temperature. According to the meteorological records, the mean decadal temperature in 1980s is 0.4~0.6 ℃ higher than the mean temperature in former 20 years.The mean decadal temperature in 1990s is 0.3~0.4 ℃ higher than that in 1980s, 0.7~1.0 ℃higher than the mean temperature in former 20 years, and 0.6~0.8 ℃ higher than he mean temperature in former 30 years. In 1990, the precipitation amounts at Qiedeke station and Piliqing station are 5.4% and 7.0% more than the multi-year mean values respectively. At Wenquan station, precipitation in 1990s increases about 20.3% compared with the annual mean value. The correlation coefficient for the precipitation between the Sailimu Lake Meteorological station and the Wenquan Station is 0.948, which means that increasing of the precipitation and runoff in neighboring area will be a indication of increasing of those inSalimu lake. Therefore, the water level of Sailimu Lake will certainly rise because of the influence of the warm-wet climate.
