基于粒子群算法的水资源优化配置研究

为了合理分配引大济湟工程从大通河调出的7.5×108 m3水量,以满足引大济湟工程受水区的生活、生产及生态用水需求,通过建立以供水净效益最大、供水系统总缺水量最小为目标函数的水资源优化配置模型,运用粒子群算法得到了受水区4类水源、5类用水户在2015、2020、2030三个规划水平年的多年平均情况下的水资源优化配置方案。结果表明,2015、2020、2030年净外调水量分别为3.10×108、6.05×108、7.34×108 m3,缺水量分别为0.69×108、0.64×108、2.15×108 m3,部分区域农业用水存在缺口,仍需采取必要的节水措施。

Study of Water Resources Optimal Allocation Based on Particle Swarm Optimization

In order to allocate reasonably the 7.5×108m3 water resources transfer from Datong river to Huangshui river and satisfy the demand of domestic water, production water and ecological water of Yindajihuang benefited regions, water resources optimal allocation model is established by taking maximization water supply net benefits and minimization water shortage of water supply system as the objective function. And water resources optimal allocation program of four kinds of water sources and five kinds of water sectors in yearly average at the 2015, 2020, 2030 target level year is obtained with particle swarm optimization. The results show that in 2015, 2020, 2030, the net diversion water is 3.10×108m3, 6.05×108m3, 7.34×108m3, respectively; the shortage water is 0.69×108m3, 0.64×108m3, 2.15×108m3, respectively; there is still a gap of agriculture irrigation in some areas; so it is important to take necessary water saving measures.
