采用地形图、航空摄影相片、中巴资源卫星和Landsat TM数字影像, 对青藏高原东南部岗日嘎布山区20世纪初以来的冰川变化进行了研究, 分析了该地区冰川对 20 世纪后期全球变暖的响应.结果表明: 20世纪初期至1980年, 研究区的冰川基本处于退缩状态, 期间冰川面积减少了13 8%, 储量减少了9 8%, 储量减少量相当于249 2×108 m3水当量, 因冰川萎缩导致其对河川径流的调节作用减弱了一半左右. 1980年以来, 本区气候表现出升温和降水增加, 在此气候变化背景下, 冰川总体呈面积减小的退缩状态, 但有一定数量的冰川处于前进之中, 这可能与不同规模冰川对气候变化的响应特点和响应时间有关.
Using topographic maps, aerial photographs, China-Pakistan Resource Satellite and Landsat TM digital images, the glacier changes in Gangagabu Mountain Area in the southeastern Tibetan Plateau since the beginning of the 20th century were studied. The influence of glaciers in this region on global change in the late 20th century The results show that in the early 20th century to 1980, glaciers in the study area were basically in a state of retreat, during which glacier area decreased by 13.8%, reserves decreased by 9.8% and reserves decreased by 249 × 108m3 water Equivalent, due to shrinking glaciers, their regulation of river runoff has been reduced by about half. Since 1980, the climate in this region has shown an increase in temperature and precipitation. In the context of climate change, the glaciers generally show an area of shrinking shrinkage, A certain number of glaciers are on the way, which may be related to the response characteristics and response time of glaciers to different climatic changes.
