摘要

陕西省长武、淳化两县水土保持工作开展较好

获得了明显的经济效益和减沙效益。本文介绍了长武县鸭儿沟、淳化县冶峪河、润镇沟等流域

通过观测资料分析计算

证明1972年以后13年比1971年以前11年输沙量减少30—70%;而输沙量的减少

既不是水库拦沙的作用

也木是由于降雨偏小

而主要是由于各项水土保持措施减轻了土壤侵蚀的结果。

Abstract

In both Changwu and Chunhua counties obvious benefits in economyand sediment reduction are obtained because of the better implement ofsoil and water conservation. For the Yargou watershed in Changwu

Yeyuhe River and Renzhengou watershed of Chunhua county

etc.

it isdemonstrated

from analysis of the observed data

that the sediment loadin the thirteen years after 1972 has been 3070% less than the value in theeleven years before 1971. The reduction is due to the effects neither fromreservior retarding nor from less rainfall

but the decreasing of soil eroson as a results of various soil and water conservation measures.
