摘 要：
以MODIS植被指数产品为数据源,利用归一化植被指数(NDVI)进行京津风沙源工程治理区荒漠化程度划分,得出2000年、2004年、2008年荒漠化等级分布图,在此基础上对研究区不同等级荒漠化进行对比分析。结果表明:京津风沙源工程治理区荒漠化程度总体上呈现减少趋势;荒漠化转移方向主要为严重荒漠化→重度荒漠化→中度荒漠化→轻度荒漠化→非荒漠化。

摘 要：
Taking MODIS vegetation index products as datum sources,and using the normalized difference vegetation index to classify the desertification degree of the area of sandstorm source control project around Beijing and Tianjin,3 distribution maps of desertification grade,in 2000,2004,and 2008,respectively were obtained.Further analysis on the extent and transformation of different desertification degree was conducted.The results showed that the desertification degree in the project area decreased generally,the main transfer direction of different types of desertification was in the sequence of very severe desertification→severe desertification→moderate desertification→mild desertification→non-desertification.
