摘　　要：USLE是适用于估算缓坡农耕地多年平均土壤侵蚀量的模型 ,由于工程建设项目水土流失预测的时段及范围与USLE的适用条件有较大差别 ,经工程建设施工扰动的土体结构与农耕地的土壤结构有较大差异 ,因此工程项目施工引起的水土流失不能直接用USLE进行估算。USLE is a model of being applicable for estimating the average o f ma ny years soil erosion quantity of gentle sloped cultivated lands. Due to the pre dicting time interval and scope of soil and water loss during engineering constr uction are big difference with the applicable conditions of USLE and the disturb ed earth structure of engineering construction also has a bigger difference with the soil structure of cultivated lands, therefore, we can not directly use USLE to estimate the soil and water loss caused by engineering construction.

关 键 词：工程建设项目 水土流失量 USLE 适用性 估算模型
