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。
In order to rationally allocate 7.5 × 108 m3 of water transferred from Datong River from Datong River Project to meet the needs of living, production and ecological water supply in the water receiving area of Dachangji Hydropower Project, by establishing a water supply system with the largest net benefit of water supply, The water resources allocation model with minimum water loss as the objective function is obtained. Particle swarm optimization (PSO) is used to obtain the water resources of four types of water sources and five types of water users in the multi-year average of 2015,2020,2030 three planning years Optimize the configuration program. The results showed that the net amount of water transferred in 2015, 2020 and 2030 were 3.10 × 108, 6.105 × 108 and 3.34 × 108 m3, respectively, and the water deficits were 0.69 × 108, 0.64 × 108 and 2.15 × 108 m3 respectively. There was water use in some areas Gaps, still need to take the necessary water-saving measures.
