摘要
根据小河沟流域“5.23”暴雨中的降雨、径流观测资料,结合调查进行分析计算的结果表明,流域内各项治理措施均收到了良好的拦泥蓄水效益,塬水不下沟,沟底淤地坝、塘坝和坡面的林草措施发挥了应有的拦蓄作用,与治理前相比,流域减水、减沙效益分别为87.2％和94.2％。
According to the observed data of rainfall and runoff in the rainstorm happened on May 23,combining with investigation,it is shown by analysis that good benefits of trapping sediment andstoring water had been obtained through various harnessment measures.Rainfall was retained ithe basin,and check dams,silt arresters and foresting and grassing measures had played a duerole in trapping sediment and storing water.Compared with the situation prior to the harness-ment,the benefits of water and sediment reduction are 87.2% and 94.2% respectively.
