摘　　要：合理计算流域综合治理后的减水减沙效益,是水土保持科学研究的一个重要课题。传统的水文法、水保法虽已广泛应用,但都有自身难以克服的缺。本文应用水文模型法,计算了韭园沟流域减水减沙效益。通过与水保法计算的结果进行比较,验证了这种计算方法的正确性、可行性。How to rationally calculate the benifit caused by reducing sediment and runoff under comprehensive harnessing, is an important subject in the field of soil conservation. The traditioaal methods subject to hydrology or conservation, although has been applied extensively,possessed some unover-comed shortcomings itself. The paper deals with the calculation of benefits of reducing sediment and runoff in Jiuyuangou watershed by using the hydrological model and compares it with the result of conservation method. It is verified that applying this method is suitable.
