面向空间均衡的水资源优化配置研究

Research on Water Resources Allocation Based on Spatial Equilibrium

首先明确水资源领域空间均衡的概念,即在保证每个计算单元内部水资源-社会经济-生态环境三大子系统之间的协调发展的基础之上,实现不同计算单元之间的协调发展。其次,将"协调发展度"的概念引入到水资源领域空间均衡的研究中,利用双层嵌套的协调发展度作为空间均衡的度量标准。在传统的水资源优化配置模型的基础上,增加了空间均衡的目标函数和约束条件,从而构建了面向空间均衡的水资源优化配置模型。并以盐城市沿海地区为例,构建了盐城市沿海地区面向空间均衡的水资源优化配置模型,通过计算得出盐城市2020年75%保证率下的水资源配置结果。

This paper defines the concept of spatial equilibrium of water resources firstly. That is,on the basis of ensuring the coordinated development among the three major subsystems of water resources,social economy and ecological environment in each computing unit,the coordinated development of different computing units is realized. Secondly,this paper introduces the concept of ＂coordinated development degree＂into the study of the spatial equilibrium of water resources,and uses two levels of nested coordinated development as the metrics of spatial equilibrium. Based on the traditional water resource allocation model,this paper adds objective function and constraints of spatial equilibrium and then constructs the water resource allocation model based on spatial equilibrium. Finally,taking Yancheng City as an example,this paper constructs the water resource allocation model based on spatial equilibrium in Yancheng City and calculates the water resources allocation result under the 75% guarantee rate of 2020 in Yancheng City.
