利用1970年左右地形图和1995、1999、2002年及2006年的Landsat-TM/ETM+遥感影像,在地理信息系统技术支持下,提取冰川边界,对祁连山疏勒南山地区的冰川变化进行研究.结果表明:研究区内的冰川在1990年代变化显著,1995年冰川面积比1970年的减少了5.8%,1999年冰川面积比1995年代的减少了3.0%,2002年冰川面积比1999年减少了1.7%,2006年冰川面积比2002年减少了3.0%.冰川的长度与冰川总面积变化趋势基本一致,且冰川规模越小的冰川变化越显著.对研究区附近气象站1957—2006年年均温和年降水量数据进行对比分析,冰川的变化基本上反映了气候的变化. Using the topographic maps of 1970 and Landsat-TM / ETM + remote sensing images in 1995, 1999, 2002 and 2006, the glacier boundaries were extracted and the glacier changes in Shule Nanshan area of ​​Qilian Mountains were studied with the support of GIS technology. It shows that the glaciers in the study area changed significantly in the 1990s, with the area of ​​glaciers dropping by 5.8% from that in 1970 and that of glaciers in 1999 being decreased by 3.0% compared with that of the 1995s. The area of ​​glaciers in 2002 dropped by 1.7% , And the area of ​​glacier decreased by 3.0% in 2006 compared with that in 2002. The length of glacier is basically the same with the change of the total area of ​​glacier, and the glacier change with the smaller glacier is more significant.The average temperature of the meteorological station in 1957-2006 Precipitation data for comparative analysis, the changes in glaciers basically reflect the climate change.
