摘　　要：分析砒砂岩地区水土流失严重的机理,采用USLE数学模型法和类比法,以大饭铺至东胜公路为例,对砒砂岩地区公路建设可能产生的水土流失量进行预测。根据预测结果,分析砒砂岩地区公路建设项目水土流失的特点,并提出公路水土保持设计原则。The reasons why the soil erosion and water loss in Pisha sandstone are serious are analyzed. By using model of universal soil loss equation and analog method, the amount of soil erosion and water loss of Da-Dong Highway which is constructed in Pisha sandstone area is predicted. According to the consequence of prediction, the characteristics of soil erosion and water loss and the principle of soil and water conservation of highway construction project in Pisha sandstone area are presented.
