中文摘要: 以中国阿尔泰山友谊峰地区为研究区,结合RS和GIS技术对该区冰川厚度、储量及面积进行了定量综合评价分析。结果表明:所研究的58条冰川,在过去的50年间,总面积减小了19.2%(平均每条冰川缩小0.363km~2);共有10条消失了。冰川平均厚度减薄了24.12m;储量减少了2.649km~3,冰川冰融水年径流量为4.88*10~6m~3。分析显示:该区小于1km~2的冰川数量占67%,但面积和储量主要集中于大于1km~2的冰川,几条较大冰川厚度和储量的变化决定了该区域的变化趋势;小冰川绝对变化量小,相对变化率大,对气候变化的敏感性强。
英文摘要: Combined with remote sensing and GIS,the spatial variability of glacier elevation changes in Youyi area of the Altay Mountain in China were obtained from two digital elevation models(one is from 1: 50 000 topographic map in 1959 and the other is from ASTER remote sensing data in 2008). Elevation changes were converted to volume changes by multiplication with the respective glacier area. This research presents elevation and area changes from 1985 to 1999 for about 58 glaciers in the Youyi area. The area of the glaciers had reduced 19. 2%. The average area of individual glaciers had reduced 0. 363km~2. 10 glaciers had melted away and the mean elevation change was-24. 12 m. The volume had reduced 2. 66km~3,and the annual glacier runoff was 4. 88 * 106m~3. The analysis shows that the amounts of the glaciers with a size smaller than 1km~2 are 67%,but the area and volume mainly concentrated in those larger than 1km~2. So the elevation and volume changes of several larger glaciers determined the change trend in this region; the absolute variation of the smaller glaciers was small,but the relative change rate was much bigger,and the sensitivity to climate change was much stronger.
