| 摘 要： | 坡面产沙计算是水土流失预测模型的基础.本文基于泥沙运动力学的基本概念,在概化的坡面上考虑影响侵蚀产沙的主要因素及其水力学关系,推导出坡面产沙量的计算公式.通过与坡面产沙实验资料对比,说明提出的坡面产沙计算公式结构合理,待定参数确定后可以作为预测坡面产沙的计算模型.

| Abstract: | The model of sediment yield on hillslope units is the basis for the soil-erosion prediction.Based on the theory of sediment transport mechanics,and the analysis of main factors,as well as their hydraulic relationships on ideal slopes,a formula which can predict the amount of sediment yield is built.Compared with several experimental results,it proved that the structure of the formula is reasonable,and it can serve as sediment yield prediction model when the coefficient is determined. |
