1: 50, 000 topographic map data,Landsat ETM + remote sensing images and digital elevation model data were used. Glacier change data from 1962 ~ 2011 were derived from this research,and the glacier variation characteristics and its response to climate change in past nearly 50a were analyzed. The results show that between 1962 and 2011,the total area of glaciers was decreasing from 109. 94km~2 to 85. 88km~2 ; shrinking at a rate of 21. 88%,with the annual decrease was approximately 0. 48km~2. By analyzing four weather stations' annual average temperature and precipitation data from 1960 to 2012,the mean annual temperature increased significantly and the annual precipitation also showed an increasing trend. The study concluded that glacier shrinkage was closely related to the temperature rising,and the glacier melting caused by rising temperatures offseted the supply by increased precipitation to some extent.
