摘要

在分析了泥河沟流域水土流失特征、水土保持措施配置的基础上，利用水土保持法－降雨较正和降水量－洪水量－输沙量相关的地区经验公式，计算了该流域的减沙效益。两种方法的结果证明，减沙效益在９０％以上。并以该流域为样点，讨论了当前水土保持治理中几个问题。

Abstract

On the basis of analysing soil and water loss features and soil and water conservation practices arrangement of Nihegou watershed

sediment reduction benefit was calculated making use of soil and water conservation method-rainfall rectification and experience formula of region related to precipitation- flood capacity-sediment discharge. Results prove that sediment reduction benefit is move 90%. Finally we discussed also four problems on soil and water conservation.
