| Abstract: | In the application of RS (remote sensing) and GIS (geographic information system) technology, the method of rapid obtaining the information of land cover and topographic condition was discussed.Based on selected evaluation factors and expert classifier of ERDAS software,reference to national soil erosion grade classification, rapid and precise evaluating the spatial difference of soil erosion could be achieved. Simultaneously,taking the Xingzi River as the example,the assessment results were validated by the hydrology station’s observation data. |
