以洪水坝河流域为例，利用1956年的地形图和2003年的ASTER遥感影像及数字高程模型，在GIS的支持下对两期数据进行统计分析，结果表明：近47年来，洪水坝河流域冰川面积减少了14．04％，长度退缩了17．28％，储量减少了2．26％。研究认为，气温显著升高是洪水坝河流域冰川快速萎缩的主要原因。在和祁连山地区、西藏以及天山地区的冰川进行对比后，发现研究区冰川消融的速率介于三地之间，初步推测是由研究区所在区域的气候和自身属性共同作用的结果。

Using the Hongshuibahe basin as an example , the analysis of topographic map in 1965 , ASTER remote sensing image data and DEM is conducted with the support of GIS .The results show that the area of the glaciers in Hongshuibahe river basin has de -creased by 14.04%, the length decreased by 17.28% and the volume declined by 2.26% during the last 47 years.The author thought that the significantly increased temperature is the main cause of the rapid glacier shrink in the Hongshuibahe river basin .And a comparative study with other glaciers in Qilianshan region , Tibet and Tianshan region shows that the glacial change rate in study re-gion is in the middle , which might be caused by the climate and glacier itself in the glacial region .
