Coordination And Coupling Nexus Of Social,economic And Environmental In Healthy City

In the process of urbanization,the urban system continuously completes the evolution from disorder to order or from order to order.The mutations in each node of the evolution process may sudden changes.When this sudden changes does not adapt the normal development of the city,it will evolve in an “urban disease” which has a negative impact on urban development and human health.With the current urbanization rate of China exceeding 50%,it is about to enter the outbreak period of urban diseases”.Healthy city becomes a good choice to control "urban disease".It is particularly important to study the mechanism of the organic combination of urban social,economic and environmental interactions from the perspective of healthy cities,so as to guide the good operation of the urban system to meet the needs of human health and well-being.First of all,this paper defines the concept of coupling and coordination,and elaborates the connotation,interactive coupling mechanism and coupling process of the coupling and coordination of the healthy city composite system in combination with the current academic research on the relationship among the society,economy and environment of the healthy city system.On this basis,an evaluation model of the coupling degree and coordination degree of the healthy city system is constructed,and the coupling degree of the healthy city system in Chongqing is evaluated by using the model.At present,Chongqing is in the running-in and coupling stage,during which society and environment are the focus of urban development.At the same time,Chongqing healthy city system is in the limit development stage.At the same time,this paper analyzes the coupling and coordination among the system layer,criterion layer and index layer,and puts forward some countermeasures and Suggestions to guide the good operation of Chongqing healthy city system,aiming at several factors that can effectively improve the coupling and coordination level of healthy city system in Chongqing.
