Study On The Coupling Relationship Between Urbanization And Ecological Environment

Urbanization is the only way of modernization.It is a strong support for regional coordinated development.However,the ecological environment problems such as environmental pollution,shortage of resources and excessive consumption of resources in the process of urbanization are bound to affect the development of urbanization.The development of urbanization requires the ecological environment as material support.The financial support and technological innovation brought by the development of urbanization,has provided the conditions for ecological and environmental protection,so the two are inseparable.How to realize the sustainable development of urbanization under the restriction of ecological environment is of great significance to speed up the modernization construction.To achieve the coordinated development of urbanization and ecological environment,first we need to clear the interaction between the two mechanisms.In this context,we establish the coupling coordination model of urbanization and ecological environment,to study the interaction and the coupling coordination degree between the two.Through the processing and analysis of the data of 18 cities in Henan Province,we get the comprehensive level of urbanization,the comprehensive level of ecological environment,the coupling degree and the coupling coordination degree of urbanization and ecological environment.According to SPSS,the correlation between the criterion layer indexes of urbanization system and ecological environment system in Henan Province is calculated,it is concluded that there is a significant positive correlation between the subsystems in the urbanization system and the ecological environment pressure,and there is also a positive correlation between the economy urbanization/ the society urbanization and the ecological environment.From the evaluation results,in addition to the high degree of the coupling coordination degree of urbanization and ecological environment of Zhengzhou,the rest of the city are low,and the level of development of the two systems is very uneven.And then according to the criteria of coupling coordination,the 18 cities are divided into three categories.Combined with the evaluation results,it can be seen that the main reason for the low coupling degree of Henan province is that the comprehensive level of urbanization is low,and then according to this situation,the countermeasures andsuggestions are put forward to promote the sustainable development of urbanization and ecological environment in Henan Province.
