AbstractA near-distance,nonlinear coupling relationship objectively exists between urbanization and the eco-environment.The issue of how to coordinate the relationship between them has become a global strategic and scientific issue.This study reveals the nature,relationship and intensity of coupling between urbanization and the eco-environment from a theoretical perspective.Based on the strength of coupling,relationships can be characterized as having very-low,low,medium,high,very-high or full coupling intensity,which correspond to the categories of random coupling,indirect coupling,loose coupling,cooperative coupling,close coupling,and controlled coupling.Together,these make up an urbanization and eco-environment"coupling tower."This study also develops an urbanization and eco-environment coupling circle theory and generates 45 coupling graphs(including linear,exponential-curve,logarithmic-curve,double exponential-curve and S-curve graphs)per 10°of rotation of the coupling circle,with different graphs corresponding to different urban development stages and development models.Of the various coupling graphs,the S-curve graph is considered the optimum,as it reflects the best interactivity scenario between urbanization and the eco-environment.Using an S-curve coupling graph,and with the help of an SD model and based on the complex one-to-one,one-to-many,and many-to-many relationships between the variables,this study develops the Urbanization and Eco-environment Coupler(UEC).The UEC is composed of 11 regulating elements and 201 variables.If one variable changes,it changes the whole,affecting the structure,function and regulation of the entire coupler.The UEC includes three spatio-temporal scales:static regulation between multiple urbanization areas and eco-environment areas at the same time,dynamic regulation between the same urbanization area and eco-environment area at different times,and dynamic regulation between multiple urbanization areas and eco-environment areas at different times.Regulation gradually promotes evolution from low-level coupling to high-level coupling between urbanization and the eco-environment.
