摘　　要：介绍了在地区级气象台站采用气象系统 92 1 0工程下发的FY 1D卫星遥感数据 ,在短红外波段的基础上建立多光谱提取积雪信息的计算方法及监测模型 ,并以2 0 0 2年 1 1月至 2 0 0 3年 5月新疆积雪遥感监测为例 ,介绍了卫星遥感监测积雪深度和积雪覆盖面积的方法 ,分析了积雪覆盖特征和变化规律。The calculation method and monitoring model of the snow cover information are introduced, by characterizing the short infrared waves and using the remote sensing data of the FY-1D meteorological satellite, which was released by the 9210 meteorological program. In addition, a new method is introduced to monitor the depth and the area of the snow cover by remote sensing, illustrated by the remote sensing monitor of the snow cover in Xinjiang from November 2002 to May 2003. The characteristics of the snow cover and the pattern of the snow cover variation are also analyzed with this method.
