Abstract:

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
