| 摘 要： | 利用MODIS卫星遥感影像，进行草场植被专题信息提取，结合地面实际调查数据，分析具有代表性的草地植被归一化植被指数NDVI的时空变化特征，结合当地卫星资料和气象水文等数据，对草场荒漠化的监测方法进行探索。实验采用了多因子指标分级数量化法，对各影响因子进行综合分析判断，评价结果由综合评价指数体现。结果证明评价指标体系适用于遥感技术进行分类评估草场荒漠化的空间变化特征分析。

| Abstract: | Taking Xilinguole grassland in Inner Mongolia as example region, the study used of the new remote sensing data of MODIS to investigate and acquire information of Xilinguole grassland analyzed the temporal and special change of NDVI. The value of each index was determined by the evaluation system, and their weight percentages were determined by using the method of analytical desertification process. Finally figured out the composite evaluation index. This monitoring and evaluation indicator system is testified to be applicable to classification and assessment on spatial distribution of desertification by using remote sensing after field investigation. |
