摘要：
Based on different land use types and diverse watersheds of Dehua district of Fujian Province, soil erosion is assessed by using Universal Soil Loss Equation (USLE). According to the results, erosion of Dehua is generally mild, among which total erosion is 952.71 x 10(3) t/a and erosion area is 2210.67 km(2). It is significant that the vast forest and grassland contribute to avoiding erosion effectively. In addition, the overlap area of Min and Jin River and Chanxi of Min River, the most frequent place of human activities, are the two highest soil erosion watersheds. The result shows that human activities have great influence on soil erosion. This article intends to provide evidence for planning and control measures of soil erosion.
