摘要

以降雨-入渗-产流原理、土壤侵蚀原理及河流输沙理论为基础

根据天然降雨、人工降雨、放水冲刷等试验研究成果及典型区域开发建设新增水土流失量分析

建立了适用于开发建设项目新增水土流失评价的数学模型法、新增土壤侵蚀系数法和水土流失系数法等3种方法

它可应用于黄河中游地区开发建设项目人为水土流失预测和分析评价

对其它地区的开发建设项目水土流失预测具有借鉴作用。

Abstract

Based on the experimental results by natural rainfall

simulated rainfall and artificially added flushing water

and the analyses of recent increase in the amounts of soil and water loss occurred in the development and construction in the typical area

we found three prediction methods for the development and construction project.They are the mathematical modeling method for evaluation of newly increased soil and water loss

the coefficient method for newly increased soil erosion

and the coefficient method for newly increased soil and water loss.The methods may be used for the prediction of man-made soil and water loss in implementing the development and construction projects in the middle reaches of the Yellow River

and for a reference to other similar area.
