基于单元优化配置方法的陕西省关中地区水资源配置研究

Water Resources Allocation in Guanzhong Region of Shaanxi Province by Unit Optimal Allocation

水资源问题已经成为制约陕西省关中地区经济社会发展的瓶颈。为此,建立了省内南水北调受水区水资源单元优化配置模型,采用遗传算法求解该模型,并建立了该地区水资源单元优化配置系统。单元优化配置和常规配置的结果对比表明:在保证各供水保证率前提的基础上可以减少总缺水量9 875万m3。这一结论可为陕西省关中地区合理配置水资源及确定引汉济渭工程调水量提供借鉴。

Water resource has become a bottleneck for the social and economic development of Guanzhong region of Shaanxi province. A model of unit optimal allocation of water resources in Shaanxi＇ s South-to-North water transfer project is set up, and the model is solved by using Genetic Algorithms （GA）. The unit water resources optimization allocation system is established. Comparison between the results of optimal allocation and conventional allocation showed that, on the premises of guaranteeing water supply, the optimal system can reduce the total water shortage by 98.75 million cubic meters. This research provides reference for the reasonable water allocation in this region and the determination of water transfer quantity for the water diversion project from Hanjiang river to Weihe river.
