Land cover of china region was analyzed using the 1km ndvi and the relative ancillary data . the result shows that the distribution of vegetation in china is correlative with space and the ndvi seasonal variations are different between various ecosystems . the land cover classification can be based on this character 利用中国区域1公里分辨率的多时相ndvi合成数据集及相关的辅助地理信息数据，对中国区域的陆表植被覆盖做了一般性分析，结果表明植被覆盖分布具有相当明显的地域性，并且各种类型陆表的ndvi表现出不同的季节性变化特征，可以此作为分类的依据；利用bayes最大似然分类法对我国东北地区进行了地表覆盖分类。
