| 摘 要： | 多期的遥感数据可以用来分析干旱荒漠区植被的空间分布格局和变化特征。本文以1989、2000和2007年3个不同时相的Landsat TM/ETM+影像为数据源，利用线性光谱混合分析和RGB彩色合成法构建一个研究框架，对古尔班通古特沙漠西缘进行植被信息的提取和变化监测分析。在混合像元分解过程中，通过多种方法选择端元，比较...

| Abstract: | Acquiring vegetation information is a key step in monitoring and evaluating arid land cover,even though it is difficult to extract desert vegetation information due to the confounding effort of soil or sand.There are many limiting factors for estimating vegetation growth in arid landscapes.Nevertheless,the growth of perennial vegetation reflects comprehensive vegetation conditions and can represent vegetation cover during a certain period.So in this study,we analyzed three years of Landsat images(1989,2000 ... |
