The Coupling Law of the Interaction between Economic Development and Eco-environment in Medium-sized City:a Case from Lianyungang City in China
City plays a strong role in the development of national economy and society.But its high economic development speed results in big resource depletion and environmental pressure.The coupling law between economic development and eco-environment refers to the collection of all interaction non-linear relations among economic,social and ecoenvironmental system during the economic development course.Many large cities have been in the medium or later stage of industrialization while medium-sized cities are just in the beginning for the industrialization.For this special development period of industrialization of medium-sized city,it is a great practical significance for analyzing the coupling law of the interaction between economic development and eco-environment.In this paper,Lianyungang City was selected as the study demonstration area.6 mathematics models for describing the quantitative relations between environment and economic development were achieved through the analysis of the relativity and quadratic and cubic equation fit and regression based on the data of environmental quality,pollutant discharge and economic development in the period of the years 1983-2006.The results showed that there exists the coupling law of the Interaction between Economic Development and Eco-environment.Through the establishment of conceptual model,the coupling law of the interaction between economic development and eco-environment in Lianyungang City was quantitatively analyzed and studied,which is helpful for the comprehensive policy-making and sustainable development in medium-sized city.
