Paper Summary

The researchers studied soil erosion in a small watershed in the Three Gorges Reservoir Region using GIS and RUSLE. They found that the area experiences slight erosion, with moderate to extremely strong erosion in certain parts. Soil erosion is most severe on slopes between 15° and 35°, especially on sloping cultivated land. The study confirms the accuracy of the RUSLE method for estimating soil erosion in the region.
