| 摘 要： | 采用遥感及地理信息系统技术,利用多时相Landsat TM/ETM影像和数字高程模型(SRTMDEM),结合中国冰川目录,获得阿尼玛卿山地区不同年份的冰川范围,进行冰川变化监测。综合分析该冰川的变化情况,计算冰川进退变化速率,并对其中4个变化较大的冰川进行详细的分析统计。结果表明:从1991年至2009年,阿尼玛卿山地区既有退缩冰川也有前进冰川,其中冰川退缩面积为15.30km2,前进面积为4.46km2。总体面积持续退缩,其中退缩最大的冰川长度缩短了900m,其它冰川也存在不同程度的变化。

| Abstract: | Based on the Landsat TM/ETM images acquired at 4different dates from 1991to 2009and the SRTM DEM,combined with Chinese Glacier Inventories data,the glacial areas of the 4times were extracted by using remote sensing image processing technology,and the changes were analyzed through GIS technology.The results showed that both glacial advancement and retreatment existed.From 1991to 2009,the area of glacial advancement was 15.30km2,while the area of glacial retreatment was 4.46km2.The total areas of the glaciers in Animaqingshan area had decreased continuously.One of the glaciers has retreated over 900meters during that period,which is the largest changes in the Animaqingshan glaciers.The other glaciers has also presented some changes. |
