摘要:

利用1970年的地形图,1995、1999、2002和2009年的Landsat\|TM/ETM遥感影像,通过遥感图像处理和GIS技术对祁连山冷龙岭地区的冰川变化进行研究。结果表明:研究区的冰川面积1990年以来变化显著,1995年冰川面积比1970年减少了13.79%,1999年冰川面积比1995年减少了21.96%,2002年冰川面积比1999年减少了10.54%,2009年冰川面积比2002年减少了6.35%。选取研究区不同规模的18条典型冰川进行面积长度的变化分析,总体情况与前面一致。

关键词: 冰川面积冰川变化;遥感冷龙岭    
Abstract:

Glaciers on the Tibetan Plateau play an important role in the earths climatic system.Regular survey of glacier change is almost impossible in most parts of the plateau.Remote sensing is a primary technique and becomes the only means in many places.GIS provides an efficient tool to analyze the status and the change of glaciers.We select the Lenglongling Mountain as the test area.Glacier variation in 1970, 1995, 1999, 2002 and 2009 were analyzed by means of satellite image and  topographical map.The results indicate that the glacier area had decreased about 13.79% from 70s to 1995 and had decreased about 21.96% from 1995 to 1999, glacier area in 2002 had decreased about 10.54% compared with in 1999.And glacier area in 2009 had decreased about 6.35% compared with in 2002.

Key words: Glacier area    Glacier change    Remote sensing    Lenglongling mountain
