Abstract

This paper studied the glaciers change information using object-oriented information extraction technology in the Heihe River Basin (including Heihe River and Beida River) since 1960s to 2007/2011. 1:50,000 topographic map data, Landsat TM/ETM+ remote sensing images and digital elevation model data were used in this research. Compared with other western mountain glaciers, glaciers retreat in the Heihe River Basin has a higher rate. Analysis of the 6 meteorological stations'annual average temperature and precipitation data from 1960 to 2010 suggests that the mean annual temperature increased significantly and the annual precipitation also showed an increasing trend. It is concluded that glacier shrinkage is closely related with temperature rising, besides, glacier melting caused by rising temperatures greater than glacier mass supply by increased precipitation to some extent
