摘要
为量化水资源配置对空间均衡的提升作用,系统评价水资源配置方案空间均衡度,研究基于水资源配置系统“水源-供水设施-受水区-用水户”的整体结构,从水源均衡、设施均衡、单元均衡和用户均衡4个方面分别选择了均衡度评价指标,构建水资源配置空间均衡度综合评价指标体系,并提出基于熵权-TOPSIS法的水资源配置空间均衡度评价方法。以昌邑市水资源配置系统为例,设置12种水资源配置方案来探究不同调控措施对水资源配置空间均衡度的影响。结果表明:该方法不仅可以量化不同调控措施对水源均衡、设施均衡、单元均衡和用户均衡的影响效果,还能够评估配置系统整体的水资源配置空间均衡度,可为水资源配置与空间均衡相关研究提供借鉴。
The uneven spatiotemporal distribution of water resources has gradually become a significant constraining factor for regional development,due to mismatches with population,productivity,and land layout.In order to meet the demands of human socioeconomic development,a series of hydraulic engineering and water supply facilities have been constructed to alter the natural distribution pattern of water resources and enhance the spatial equilibrium of water resource allocation.Water resource equilibrium allocation is not simply a matter of allocating a single water source to a single user,but involves complex water quantity distribution composed of multiple water sources,users,and hierarchical engineering.Therefore,it is essential to analyze the spatial equilibrium of water allocation from the perspective of the overall water allocation system.An evaluation index system has been established,consisting of four subsystems:water source equilibrium,water supply facility equilibrium,unit equilibrium,and user equilibrium.The water source equilibrium subsystem employs the matching degree between the water supply proportion of each water source and its available water quantity proportion as an indicator.The water supply facility equilibrium subsystem selects the matching degree between the water supply proportion of each water supply facility and the scale of water supply as an indicator.The unit equilibrium subsystem treats each administrative region as a computational unit and utilizes the matching degree between the population of each unit and the water resources as an indicator.The user equilibrium subsystem uses the matching degree between the water supply proportion of each water user and the demand for water as an indicator.Subsequently,12 different scenarios are designed,and the entropy weight TOPSIS method is utilized to comprehensively evaluate the spatial equilibrium level of water resources.The entropy weight TOPSIS method is an effective multi-attribute decision-making analysis approach that fully considers the imp
