| Abstract: | This paper expounds method and order of soil erosion survey by remote sensing and GIS in China. Classify system and intensity grade index of soil erosion are founded and map of soil erosion intensity in China. We compile the digital map of soil erosion by using man computer interactive interpreting and built soil erosion spatial database based on GIS; then we make a comprehensive and deep analysis for the survey results. These results show the distribution characteristics and rules of soil erosion. That is the areas and intensity of soil erosion gradually increase from east to west in China and focus some continuous area. Finally, we suggest some synthesis countermeasures for treating soil erosion |
