摘    要: 介绍了利用遥感和地理信息系统栅格技术进行三峡库区水土流失动态监测的过程和方法。首 先利用遥感图像处理软件ERDAS进行了土地利用的分类和植被覆盖度的计算,然后利用地理 信息系统软件ARC/INFO中GRID工具进行各类水土流失因素图的空间分析,估算各县或小流 域的水土流失强度,并计算各种强度下的水土流失面积。

关 键 词:GIS  RS  三峡库区  水土流失

Abstract:The process and method on dynamic monitoring of water and soil loss for the Threee Gorges reservoir area using RS and GIS are introduced.Firstly,the classification of land and the calculation of available coverage of plant cover are performed by remote sensing image handling software ERDAS,and then,the space analyses of varieties of water and soil loss are done by the ARCGRID of geographical information system software ARC/INFD,and finally,the intensities and the areas of water and soil loss for every counties or small valleys for different intensities are estimated respectively.
Keywords:GIS  RS  GRID  water and soil loss  Three Gorges reservoir area
