中文摘要: 选取了博格达峰地区的112条冰川,对近50年来该区的冰川变化情况进行详细分析。结合1:5万地形图、Landsat ETM+影像及数字高程模型数据,通过雪盖指数提取的方法,参照专家指导意见进行冰川边界的再次修订,得到1962~2011年该区的冰川变化数据,并分析了过去近50年来冰川变化特征及其对气候变化的响应过程。结果表明:1962~2011年,研究的112条冰川总面积从109.94km~2减少到85.88km~2,减少了24.06km~2,退缩率为21.88%;冰川平均面积从0.98km~2减小为0.78km~2。结合蔡家湖、乌鲁木齐、达坂城、奇台气象站气象资料分析,天山博格达峰地区冰川萎缩与该地区气温快速上升关系密切,气温上升导致的冰川消融在一定程度上抵消了降水增加对冰川的补给。
英文摘要: 1: 50, 000 topographic map data,Landsat ETM + remote sensing images and digital elevation model data were used. Glacier change data from 1962 ~ 2011 were derived from this research,and the glacier variation characteristics and its response to climate change in past nearly 50a were analyzed. The results show that between 1962 and 2011,the total area of glaciers was decreasing from 109. 94km~2 to 85. 88km~2 ; shrinking at a rate of 21. 88%,with the annual decrease was approximately 0. 48km~2. By analyzing four weather stations' annual average temperature and precipitation data from 1960 to 2012,the mean annual temperature increased significantly and the annual precipitation also showed an increasing trend. The study concluded that glacier shrinkage was closely related to the temperature rising,and the glacier melting caused by rising temperatures offseted the supply by increased precipitation to some extent.
