摘要
运用泥沙运动力学基本理论,建立坡面土壤侵蚀公式及中大流域产流产沙数学模型,根据实测降雨径流资料,对模型进行验证,分析了模型参数的区域变化特性,运用长系列资料,分析了模型参数与流域治理的关系。
The condition of watershed has changed with human activities.Runoff and sediment has varied at the same times. A physical conceptual model of runoff and sediment for long series and middle and large basin is established after mechanic analysis and mathematical deduction. The mathematical model has been verified by field data. The region variation of model parameter has been analyzed. The variation of model parameter with water conservation measures has been calculated.
