中文摘要	利用遥感技术对三峡库区内水蚀荒漠化进行了监测。通过对2003年三峡库区蓄水前和2009年蓄水至175 m后两期航空遥感正射影像的解译,提取出了工作区水蚀荒漠化信息,总结出期间三峡库区蓄水后水蚀荒漠化的变化情况。监测结果表明,三峡库区蓄水至175 m后,区内水蚀荒漠化整体上呈现明显改善的趋势。不同程度的水蚀荒漠化土地面积都在减少,其中,中度水蚀荒漠化土地面积减少最多,从改善程度来看,以轻度水蚀荒漠化的改善程度最高。
英文摘要	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.
