Abstract

Glaciers are sensitive indicators of climate change. Spatial-temporal variations of glaciers have been analyzed in the Geiqu basin through employ the technique of geographic information based on two glacier inventory data. Some conclusions can be drawn as follows. (1) Currently, glaciers of Geiqu basin concentrated distribute in the North Slope with the height between 5900 ~ 6000m. The glaciers with the area of less than 0.5 km2 are the most developed and the ones with the area of above 2 km2 are given priority to (79.35%). The glacier reserve is 12.5 km3. During 1978 to 2010, the glaciers of the basin showed retreat trend. The reserves declined by 16%. The glaciers with the area between 0.1 ~ 0.5 km2 and the area between 2 ~ 5 km2 had the most significant retreat. (2) When the end of the glacier gets into the lake, glacier has a higher sensitivity to climate change and an amplification effect on the related feedback. When such glaciers are in intense melting period, leaking water lubricates sled which causes a large scale collapse. The occurrence probability of the ice lake outburst flood is larger than the situation when the end of the glacier does not into the lake, which should be given more attention.
