| 摘 要： | 使用多源遥感数据，并结合先进的遥感图像处理技术，通过人机交互判读的分析方法，对云南怒江流域进行水土流失遥感调查及动态监测。结果表明，云南怒江流域水土流失面积占总面积的55．75％，且以轻度、中度和强度为主，极强度和剧烈很少，不到总面积的5％。从20世纪80年代至20世纪初，云南怒江流域水土流失强度减轻面积大于加重面积，流域水土流失状况出现好转。

| Abstract: | On the basis of multi-remote sensing data and interpretation techniques,investigation and supervisory of soil and water loss in Nujiang valley of Yunnan province were carried out using the analysis method of man-computer interactive.The result showed that the area of soil and water loss occupied 55.75%,and it was mainly in the slight,moderate and strong degree,while scarcely in the very strong degree,with an area percentage of less than 5%.The decreased area of soil and water loss was larger than the increased area from 1980s to early 20th,and the soil and waterloss was alleviated. |
