摘　　要：利用2000年前后获取的TM/ETM遥感影像,结合其他资料,提取长江流域水土流失状况信息(包括水土流失的类型、面积和强度),总结该流域内水土流失分布规律,从地质环境角度研究水土流失的现状和变化原因,从地学角度提出水土流失治理建议。In this paper, the soil erosion conditions such as soil erosion type, area and intensity of the Yangtze River basin were extracted from the TM/ETM images acquired in 2000 and other information,the distribution of the soil erosion in the basin was summarized, the situation and the variation reason of the soil erosion were studied from the point of view of the geological environment. In addition, some suggestions concerning the measures for harnessing soil erosion are put forward on the basis of earth science.
