Abstract:

By analyzing spectrum characteristics of snow，clouds and diferent land covers in the Qilian Mountain region based on MO-DIS data from July 2003 to March 2005，a new method for snow discrimination is presented on the basis of former researches，which combined NDSI(Normalized Diference Snow Index)and band 18，band 3 1 of MODIS to discriminate snow from clouds，saline，ice，desert，etc．with a step—by—step approach．Both result analysis and examination show that snow in the Qilian Mountain region canbe efectively discriminated by the method of this article．

Key words: the Qilian Mountain, snow, NDSI, brightness temperature, step—by—step approach

摘要：

对祁连山区积雪、云和各种下垫面进行光谱分析，利用2003年7月至2005年3月的MODIS数据资料，在前人所做研究工作的基础上提出利用归一化差值积雪指数NDSI(Normalized Diference Snow Index)和中分辨率成像光谱仪(Moderate Resolution Imagigng Spectroradiometer)的band 18和band 31的结合，采用逐步逼近法去除大部分云、盐湖、冰面、沙漠、戈壁等对积雪判识的干扰，从而判识出祁连山区积雪。由结果分析和检验显示，利用本文方法可以比较有效识别出祁连山区积雪
