Study On The Coupling Relationship Among Urbanization-Economic Development-Ecological Environment

With the economic growth and the acceleration of urbanization,the people's living standards have been significantly improved.However,with the infinite demand for the environment and pollution emissions,people also bear the punishment from the ecological environment.How to change this situation has become the focus of attention of all countries in the world.This paper establishes a coupling relationship model by establishing three subsystems of urbanization,economic development and ecological environment,and quantitatively studies the coupling and coordination relationship among the three.The urbanization development level of Beijing-Tianjin-Hebei region was comprehensively evaluated from the aspects of population urbanization,spatial urbanization and social urbanization;the degree of economic development was measured from three aspects: development scale,industrial structure and development potential;the ecological environment was evaluated in four aspects: resources,ecological elements,ecological pressure and ecological response.This paper selects the data of Beijing-Tianjin-Hebei region from 2005 to 2016 for 12 years.The comprehensive evaluation scores of the three subsystems were calculated to obtain the coupled and coordinated relationship among urbanization,economic development and ecological environment in Beijing,Tianjin and Hebei,and the spatial differences of the three places were compared.The empirical research results show that the coupling relationship among urbanization,economic development and ecological environment is in constant optimization,from imbalance to intermediate coordination and even advanced coordination.The ecological environment has become the biggest constraint to the future development.Therefore,in the process of urbanization and economic construction in the future,how to strengthen ecological environmental protection and make urbanization and economic construction more compatible with the ecological environment is the biggest test.Figure 50;Table 15;Reference 48...
