Abstract:Dynamic monitoring of water erosion desertification in the Three Gorges Area was carried out by using remote sensing technology so as to find out the dynamic changes of water erosion desertification. The water erosion desertification information was extracted through the interpretation of two phase aviation orthoprojective images taken separately in 2003 and 2009, and then the changes of water erosion desertification in those years were summarized. The monitoring results show that the condition of water erosion desertification in the Three Gorges Area was improved obviously. The Three Gorges Area began storing water in 2003, and the water reached its highest level of 175 m in 2009. All kinds of water erosion desertification was reduced obviously, especially the moderate desertification. As for the improving degree, the mild water erosion desertification has been improved most evidently.
