黄土坡面地表处理与产流过程研究

The Study on Relationship Between Slope Treatment and Overland Flow in the Loess Area

在径流栽培技术研究的基础上，应用坡面流的运动波理论分析了黄土地区坡面实施防渗剂处理、拍光处理和自然坡面的产流过程，确定了模型参数，并应用数值解法对三种处理坡面分别进行了数字模拟计算，其结果可直接应用到集流栽培设计中。

On the basis of water-harvesting plant techniques,this paperhas analysed the runoff yield course of slope with infiltration-preventing reagent,smooth and firm slope after grass were eliminat-ed,as well as natural slope in the loess area by using overland flow kinetic wave theory.Futbermore,we determined the parameters of the equation ,and carryed out digital simulation calculation of runoffyield for different sloping faces.The results may directly been used to the design of water-harvestingplantation.
