| 摘 要： | 为分析玛纳斯河流域冰川积雪覆盖的变化特征，应对气候变化条件下区域水资源的变化，以MODIS数据为基础，利用归一化差分积雪指数方法提取了玛纳斯河流域的冰川积雪覆盖面积，研究了该流域1998—2006年的冰川积雪覆盖变化。结果表明：该流域的年际冰川积雪覆盖区域的平均海拔高度在1998—2002年表现为下降过程，在2002—2006年表现为上升过程；1998～2001年冰川积雪面积有一个缓慢增大的过程，而自2001年以后，出现了年均8km^2左右稳步减小的过程；另外，该流域冰川积雪面积与平均温度、降水分别呈显著负相关和正相关关系。这说明气候变暖对玛纳斯河流域山区冰川积雪的消融有明显促进作用。

| Abstract: | To analyze the snow and ice cover change in Manasi river basin for the regional water resource assignment in the condition of climate change,normalization difference snow index （NDSI） method has been used to obtain the snow and ice cover areas in this basin. Through analyzing its change characteristic from 1998 to 2006, the result shows that the annual changes of elevation in snow and ice cover areas in Manasi basin have an increasing trend. At the same time, the cover areas are decreasing at 8km^2 every year. Also, there is a remarkable positive correlation relationship between the cover areas of snow and ice and the temperature,but there is a remarkable negative correlation relationship between the cover areas and the rainfall. |
