| 摘 要： | W EPP是美国农业部在国内也得到了一定的推广和应用。在黄土高原地区因其土壤、气象上的特殊性,应用该模型之前应该得到很好的验证。本文用W EPP模拟的结果与实测资料进行对比,分析了其在黄土高原地区的适用程度,存在的误差及其原因。结果表明该模型对径流的模拟相对较好,对侵蚀量的结果比较差,与采用平均值效果相比同样不具备优越性。因此对W EPP在黄土地区的使用应十分谨慎。

| Abstract: | The water erosion prediction project(WEPP) model was developed by the USDA for soil erosion assessment and conservation planning.Nowadays the WEPP was popular extension and application in China.In view of the particularity about the soil,climate in loess plateau,the WEPP model should be validated before it is applied to prediction.In this paper,compared the simulated results with the observed data to analyze the suitability of WEPP in loess plateau,the error and it's reason,the results show the WEPP model with a good simulation to the runoff data but poor with the erosion data,and using the average value was still not with suporiority.So the WEEP model applying into loess plateau still should be very careful. |
