本文根据系统工程理论方法,通过建立数学模型,对泥河沟流域塬(坡)面配置的水土保持工程体系进行了优化研究,结果表明,渭北黄土残塬沟壑区,塬(坡)面水土保持工程应以修建梯田为主,同时在村庄道路径流集中处修筑蓄水池、水窖群等蓄水工程效益最佳。 According to the theory of system engineering, through the establishment of mathematical model, the soil and water conservation engineering system on the plateau (slope) surface of the Nihegou watershed was optimized. The results showed that the soil and water conservation in the gully area of ​​Loess Plateau The project should be based on the construction of terraced fields, and at the same time, construct reservoirs at the village road runoff concentration points. The water storage works such as the cellar group will be most effective.
