基于GWAS模型的邯郸市水资源优化配置研究

Optimal Allocation of Water Resources Based on GWAS Model in Handan,China

近年来邯郸市上游河流入境水量减少,地下水开采总量愈加限制,难以满足不同行业大幅度上升的用水需求,加之南水北调、引黄和引卫工程建设后对一部分行业供水水源的置换,邯郸市水资源短缺问题和供需矛盾越发尖锐复杂。通过分析邯郸市的水资源特点及水利工程分布特征,并对各区县进行水量供需预测,基于GWAS构建了邯郸市多水源、多用户和多目标的水资源优化配置模型。结果显示:邯郸市2025年P=50%保证率的总需水量为3013.01×10^(6)m^(3),总分配水量为2473.97×10^(6)m^(3),缺水率为17.89%;P=75%保证率的总需水量为3434.90×10^(6)m^(3),总分配水量为2498.22×10^(6)m^(3),缺水率为27.27%。缺水主要集中在第一产业。配置结果符合邯郸市的实际用水情况,研究成果可为邯郸市水资源管理提供技术参考。

In recent years,the inflow of upstream rivers in Handan City has decreased,and the total amount of groundwater exploitation has become more limited,which fails to meet the rising water demand of different industries.In addition,due to the replacement of water supply sources for some industries after the construction of the South-to-North Water Diversion Project,the Yellow River Diversion Project,and the Yinwei River Water Diversion Project,the shortage and the contradiction between supply and demand of water resources in Handan City are becoming acute and complex.By analyzing the characteristics of water resources and the distribution characteristics of water conservancy projects in Handan City,the water supply and demand of each district and county in Handan City are predicted,and a multi-source,multi-user,and multi-objective optimal allocation model of water resources in Handan City is constructed based on GWAS.The results show that the total water demand in Handan City with a guarantee rate of P=50%in 2025 is 3013.01×10^(6)m^(3);the total water allocation is 2473.97×10^(6)m^(3),and the water shortage rate is 17.89%.The total water demand with a guarantee rate of P=75%is 3434.90×10^(6)m^(3);the total water distribution is 2498.22×10^(6)m^(3),and the water shortage rate is 27.27%.The water shortage is mainly concentrated in the primary industry.The allocation results are in line with the actual water consumption situation in Handan City,and the research results can provide a technical reference for water resources management in Handan City.
