新疆是干旱半干旱地区，积雪是水资源的重要组成部分，对环境变化起着至关重要的作用，对新疆积雪的动态变化进行监测是十分必要的。提取了163条无云带，计算了归一化差异雪指数（NDSI），反映了积雪覆盖度和积雪深度，并与野外观测结果进行了比较，结果是可信的。
Snow is an important component of water resources in Xinjiang,where is arid and semi-arid area,and it is also plays a crucial role in environmental change.It is necessary to monitor the dynamic variety of snow coverage.In this paper the authors chose 13 prefectures regions in Xinjiang as monitoring objects,through processing and analyzing of nearly 2 500 MODIS orbit data from Jan.2002 to Dec.2003,extracted 163 swathes which were cloud free,then calculated NDSI(Normalizing Deference Snow Index) to show the snow coverage and depth.Comparing with field work observations,the results are credible.
