中文摘要：

针对利用多源遥感数据进行积雪覆盖监测的需要,在分析不同深度与面积的积雪实测光谱基础上,探讨了在利用NDSI方法进行积雪覆盖遥感监测时,不同积雪深度对其的影响,并以HJ-1B卫星以及MODIS卫星为例,研究了不同积雪面积对遥感积雪反演的影响。结果表明,积雪深度几乎对遥感积雪覆盖监测的结果没有影响,而在积雪面积方面,受所使用的遥感影像空间分辨率的制约,对遥感积雪监测的结果有一定影响。

英文摘要：

For the needs of snow cover monitoring using multi-source remote sensing data,in the present article,based on thespectrum analysis of different depth and area of snow,the effect of snow depth on the results of snow cover retrieval using nor-malized difference snow index（NDSI）is discussed.Meanwhile,taking the HJ-1Band MODIS remote sensing data as an exam-ple,the snow area effect on the snow cover monitoring is also studied.The results show that：the difference of snow depth doesnot contribute to the retrieval results,while the snow area affects the results of retrieval to some extents because of the con-straints of spatial resolution.
