基于公平-经济-减排的多目标水资源配置模型

A Multi-objective Water Resources Allocation Model Based on Equity-Economy-Emission Reduction

为了解决水资源分配中的公平、经济和可持续问题,提出一种多目标水资源优化配置模型,在提高经济效益的同时减小区域总污水排放量;以青海省龙羊峡水库为研究对象,分析研究区域的水资源状况,以区域系统经济效益、各用水分区的配水满意度最大化和区域污水排放总量最小化为目标,建立多目标水资源优化配置模型探究区域的最佳配水方案;根据区域实际情况设定较高、较低2个不同可用水量水平,探究在用水分区不同最低配水满意度下配水方案的变化。结果表明:多目标水资源优化配置模型生成的配水方案经济效益最高可提升约2.57×10^(10)元,污水排放量最高可减少约1.8×10^(7) t;该模型在提高经济效益和分配公平性的同时促进污水减排,实现减排和经济效益之间的权衡,为区域不同情景下的水资源配置和规划提供经济、有效的决策支持。

To further address the issues of equity,economy,and sustainability in water resource allocation,a multi-objective water resource optimization allocation model was proposed,which aimed to enhance economic benefits while reducing the total regional wastewater discharge.Taking the Longyangxia Reservoir in Qinghai Province as the research subject,the water resource conditions of the research area were analyzed,and a multi-objective water resource optimization allocation model with the goals of maximizing regional system economic benefits,maximizing the satisfaction of water distribution in each water-use sector,and minimizing the total regional wastewater discharge was found to explore the optimal water distribution scheme for the region.Based on the actual regional conditions,two different levels of higher and lower available water were set to investigate the changes in water distribution schemes under different minimum satisfaction levels of water-use sectors.The results show that the water distribution schemes generated by the multi-objective water resource optimization allocation model can increase the economic benefits by up to approximately 2.57×10^(10) CNY,and reduce wastewater discharge by up to approximately 1.8×10^(7) t.The model promotes wastewater reduction while improving economic benefits and distribution fairness,achieving a balance between emission reduction and economic benefits,and can provide economic and effective decision support for water resource allocation and planning under different regional scenarios.
