以丰都县作为研究对象,利用土壤流失方程,对土壤侵蚀强度进行了分级,并分析研究区土壤侵蚀与主要影响因子间的响应关系.研究表明,丰都县的土壤侵蚀强度等级以轻度为主,强度侵蚀、极强度侵蚀和剧烈侵蚀均有发生,但所占百分比不大.同时,在数量、空间分布及土地利用方式上对不同的土壤侵蚀强度进行分析.%With Fengdu County as the research object, the revised universal soil loss equation ( RUSLE) was used to grade the soil erosion intensity and analyze the relations between soil erosion and main influencing factors. The results indicated that most of the soil in Fengdu County is mildly eroded, and the soil in some areas is also seriously and severely erosed, but the proportion is small. Finally the quantity, spatial distribution and land use patterns of different soil erosion intensity were anlayzed.
