摘要

该文根据丰富的实测小区资料，在传统的水保坡面措施减水减沙效益计算的基础上，运用同频率对比求出小区不同水保坡面措施的减洪量，并将其推算到大流域，算出流域不同水保坡面措施减洪量，然后利用流域水沙关系“以洪算沙”

算出措施减沙量。由此得出一套较为切实可行的水保坡面措施减水减沙效益计算方法，并在国家“八·五”黄河水沙变化研究中得到成功运用。

Abstract

Based on abundant experimental data and traditional method of calculating the benefits of runoff and sediment reducing by soil and water conservation sloping measures

this paper obtains the flood reducing amount of different measures on experimental plots through constrasting the flood discharge of controlling area with uncontrolling area in same flood frequence

and popularize this results to whole watershed .We get the flood reducing amount under different measures in watershed

and then use the flood～sediment relationship to calculate the sediment reducing amount by flood reducing amount in whole watershed

we get an avilable method to calculate the benefits of runoff and sediment reducing by different measures.
