黄土高原丘陵沟壑区水土保持措施的优化配置及效益分析

Optimal Allocation of Soil and Water Conservation Measures and Benefits Analysis in Hilly and Gully Region of Loess Plateau

从黄土高原丘陵沟壑区的实际出发,利用系统工程原理建立水土保持措施配置的优化数学模型。突出研究坡面和丘陵沟壑区小流域坝系水保工程措施的建模方法,并且提出不同类型区域的优化指标以解决大面积的水保规划治理问题,通过某一区域的数值指标来验证结果的合理性。

Based on the actual condition in Hill and Gully Area of the Loess Plateau,an optimized mathematic model of water and soil conservation measures is constructed by using principals of system engineering in this paper. The paper focuses on the slope and modeling methods of the small watershed dam system in the area,and the optimized indexes of different regions are put forward to solve the problem of water conservation planning and governance in large areas,the reasonableness of calculated results is verified by the numerical indexes of a certain region.
