摘要：
Taking Yuyao city as the study area, using GIS technology to establish a database of soil ero-sion. Based on the database, soil erosion in the study area was Evaluated and the dynamic variation of soil erosion intensity was analyzed. The results showed that during the past ten years from 2004-2014, the overall situation of soil erosion in Yuyao city had improved, and the total area of soil erosion decreased year by year, with an average annual reduction rate of 3.3199 km2/a. But high intensity erosion area increased due to mining, quarrying, road building caused by. And some area had the evil trend, however the area was not large. In the process of the dynamic transition of erosion, the weakening area of erosion mainly came from the transition of slightly eroded area to non-apparently eroded area. the exacerbating erosion area mainly came from the transition of non-apparently eroded area to the slightly and moderately eroded area.
