| 摘 要： | 通过对遂宁组紫色土产流、产沙侵蚀的观测,运用迄今为止最为复杂的土壤侵蚀预测模型WEPP模型进行单次降雨侵蚀预测,与实测值比较,并对比通过气候生成器CLIGEN和断点生成器BPCDG的产生的气候参数对预测值的影响。通过分析比较结果,认为WEPP模型对遂宁组紫色土侵蚀过程预测合理,而且利用断点生成器BPCDG的预测结果要优于气候生成器CLIGEN的预测结果。

| Abstract: | The paper applied the WEPP model, which is the most complicated soil erosion-forecasting model to predict the rainfall corroding, and contrast with measured value, though the observation on the runoffs and sediments of Suining group purple soil, then contrast the influence to the forecasting value between the climate generator and breakpoint climate data generator. By way of analyzing to the result, thinking that the WEPP model applying on the group purple soil erosion is reasonable, and the forecasting result of using the breakpoint climate data generator is superior to use the climate generator. |
