| 摘 要： | 为了快速地提取荒漠化的敏感区域,选择了MODIS数据植被指数NDVI的时间序列分析的方法。具体尝试了三种方法:MMAA合成法、NDVI最大值的RGB组合法、NDVI最大值比较法。其中MMAA合成法监测一年内的植被动态是很方便快捷的,而后两种方法对于提取年度间的变化区域是比较直观有效的。

| Abstract: | In order to monitor the desertification sensitive areas,we choose MODIS data and use the time series for analyzing method of the vegetation index-NDVI. We have tried three methods: MMAA composing,RGB combinination of the maximal NDVI,comparison of the maximal NDVI. Among the three methods,MMAA composing method is the most convenient and quick one for monitoring the vegetation dynamics in one year,and the latter two methods are more effective for monitoring the changes in vegetation index between two years. |
