【摘要】 根据渭北高原沟壑区水土流失综合治理工程体系配置的特点，结合衣业灌溉要求，将沟道水土保持工程和水利工程中的小型水库有机结合起来，运用系统工程优化理论的方法，建立了该地区小流域沟道工程体系配置的优化数学模型式。最后，以淳化县花河沟流域沟道工程体系配置优化为例对模型的应用进行了演示。更多还原

【Abstract】 According to the distinguishing feature of engineering system disposition of soil and water loss control comprehensiviy in Weibei Loess Plateau and using optimization theory of System Engineering, a optimization mathematical modle of gully engineering system disposition in small watershed is developed, which considers the demands of irrigation, combines soil and water conservation engineering with small reservoir of water conservany works’s and regards them as one system. Lastly with optimizing the gully engineering system of Nihegou small watershed in Chunhua county, demonstrate the application of the modle.更多还原
