| 摘 要： | 以攀枝花市为例,主要选用美国陆地卫星2003年的Landsat-7 ETM+遥感数据、1∶10万地形图,运用ERDAS/IMAG INE遥感图像处理软件及M apG IS软件提取对水土流失影响较大的植被覆盖度、地形坡度、沟谷密度、土地利用类型等因子;根据中华人民共和国行业标准《土壤侵蚀分类分级标准》(SL 190-96),建立攀枝花市水土流失强度面蚀分级指标,为进一步水土流失监测研究提供科学依据。

| Abstract: | Taking Panzhihua city for an example,based on landsat-7 ETM+ original data of 2003 and 1∶100000 topographic map,the authors have extracted leading factors of soil and water loss by ERDAS/IMAGINE and MapGIS software,such as vegetation cover,slope,gully density,land-use type,and so on.According to the industry standard of the People's Republic of China standard for classification and gradation of soil erosion(SL 190-96),the authors have established surface erosion gradation index of soil and water loss,which provides scientific basis for the further monitoring and study of soil and water loss. |

| Keywords: | remote sensing(RS) geographic information system(GIS) soil and water loss factors remote sensing information extraction gradation calibration |
