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,致使区域水环境不断恶化,并成为制约区域经济社会发展的重要因素。为了协调水环境与经济发展间的关系,许多国家开展水环境功能区划研究,为流域管理和调控提供科学依据,但是这些研究大多以水体为对象,较少关注水陆空间联系以及水环境承载能力对区域产业布局的限制,忽视了经济社会发展对水环境胁迫作用。为此,综合考虑水环境容量和压力两方面要素,提出水环境约束分区方法,并以无锡市区为例讨论了分区评价单元划分、指标选择与处理等技术方法,通过水环境容量和水环境压力的矩阵分析,将研究区划分为高压高容区、高压低容区、低压高容区和低压低容区等4种类型区,据此提出产业准入与布局调整导向。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。
Along with the highly speedy development of economic and society in the developed area in China,with the quantity of pollution emission such as agricultural fertilizers,industrial wastewater and domestic sewage sharp increasing,the water environment has been deteriorated continuously and become a limiting factor to regional development.For harmonizing the relationship between economic development and water environment,many countries attempted to study the water environmental function zoning so as to provide a scientific basis for the basin management,but these researches ignored the spatial relation between water and land,even the index system only concluded the environmental genes but not threatening genes by human activity.This paper discussed the methods of constraint regionalization of water environment based on the capacity and pressure of water environment,including how to divide the assessed units,choose and manage the assessed elements.Then,as a case study,Wuxi City was divided into four types by the method of matrix analysis,such as high-pressure and high-capacity area,high-pressure and low-capacity area,low-pressure and high-capacity area and low-pressure and low-capacity area.Finally,this paper presented the schemes of industrial admittance and the policy of industrial development direction respectively,which was a very important base for harmonizing the industrial development and the bearing capacity of water environment.
