摘　　要：为进行中分辨率成像光谱仪的EOS/MODIS数据与FY3/MERSI数据归一化植被指数(NDVI)的差异性分析,分别选取2008年8月16日、2009年8月30日EOS/MODIS和FY3/MERSI遥感数据,分林地、灌丛、旱田、水田、城市、沙地6种不同地类进行了植被指数计算,并从数据相关性、直方图分布、特征空间分布等方面进行了分析比较。结果表明,MODIS/NDVI和MERSI/NDVI有着共同的直方图走势,动态范围基本一致,各类地物的反演结果均表现出很好的线性一致性,其中林地R2最高,达到了0.8624。The difference of vegetation index of EOS/MODIS and FY3/MERSI were reported in this paper. EOS/MODIS and FY3/MERSI data of august 16,2008 and august 30,2009 were acquired respectively and the vegetation index of EOS/MODIS and FY3/MERSI were calculated in different land, such as forest, bosk, corn, paddy, city, sandlot and so on. This paper analyzed the relationship between MODIS/NDVI and MERSI/NDVI of the same region at different time, based on histogram and Feather Space methods. The results showed that their shapes were the same in the histogram, and the range of their values had consistent region. Each inversion result of various kinds of ground objects showed a better linear consistency, the maximum R 2 was forest land, which reached to 0.8624.
