基于公平性评估的滨湖城市水环境容量配置研究——以无锡市区COD配置为例

摘要:
随着发达地区经济社会的快速发展,水污染物排放量急剧增加,甚至超出区域水环境容量,致使水环境不断恶化,并成为制约区域经济社会发展的重要因素.本文综合考虑水环境容量供给能力和需求状况两方面要素,以流域为基本评价单元,采用综合分区技术和矩阵向量模型,构建水环境容量总量指标分配方法,并以无锡市区为例提出水环境容量的多情景配置方案.在此基础上,引入基尼系数方法测度不同方案的公平性,据此进行情景方案的优选.总体上,中心城区及东北部地区配置较大的环境容量,位于太湖上游的西部和西北部地区以及望虞河沿线地区环境容量供给能力较低,配置较少的环境容量.研究结果可为协调区域产业发展与水环境关系、制定差别化的产业准入政策提供科学依据.

Abstract:
Along with the high speed development of economy and society in the developed area in China,the quantity of water pollution emissions increased sharply to a degree well beyond the regional water environmental capacity.The water environment has been deteriorated continuously and becomes a restrict factor to regional development.Taking the basins as a basic spatial unit,this paper discussed both sides of supply ability and demand conditions of water environmental capacity comprehensively,and proposed a method of total index allocation of water environmental capacity include regionalization technique and vector space model.Moreover, taking Wuxi City as an example,this paper proposed multi-scene configuration program of water environmental capacity.First,Gini coefficient method was used to measure the fairness of different programs.Then optimization of different programs was carried out,and the scientificity and operability of allocation scheme were enhanced.As a whole,the central city and northeast region had been allocated more water environmental capacity quantity than the upriver of Lake Taihu and the region along the Wangyu River.The results provide a scientific basis for harmonizing the relationship between regional industrial development and water environment, and policies-making of differentiated industrial access.
