摘要
WEPP模型是一种基于侵蚀过程的计算机土壤侵蚀预测模型。本文通过对遂宁市紫色土产流、产沙侵蚀的观测,运用WEPP模型进行单次降雨侵蚀预测,并与实测值进行比较。通过分析比较结果,认为WEPP模型对紫色土侵蚀过程预测合理,为进一步研究WEPP模型对紫色土多年侵蚀预测提供参数参考。
The Water Erosion Prediction Project (WEPP) watershed scale model was developed by the USDA for soil erosion assessment and soil conservation planning. In this paper, throughout the observation of the erosion for the runoff producing and sediment of the purple soil in the Suining city, applied the WEPP modeling to predict the single rainfall erosion and compared it with the measured value. Throughout the effect analyzing and comparing, and it was found that the prediction of WEPP modelling for the erosion process in purple soil is reasonable, and the effect offered favorable reference parameter for the further studies on the WEPP modelling apply to prediction of the average annual erosion.
