A Study On Coupling Coordination Development Between Urbanization And Eco-environment In Sichuan

With the rapid progress of urbanization,the impact on the ecological environment was also increasing,exploring the interaction relationship between urbanization and ecological environment than itself was more attractive.How to coordinate the relationship between urbanization and ecological environment was an urgent problem to be solved in the modernization construction.Therefore,it was of great significance to discuss the coupling and development between urbanization and the ecological environment in Sichuan.Based on the existing research results and the actual situation of Sichuan Province,the urbanization and ecological environment evaluation index system was constructed,and the relevant data of 2006-2015 was collected.The coupling and coordination model of urbanization and ecological environment was used to analyze the coupling and coordination relationship between urbanization and ecological environment in Sichuan;And by the ArcGIS10.1 thematic map to reflect it's temporal and spatial evolution characteristics.Through the empirical analysis,this paper drawd the following conclusions:(1)From the perspective of Sichuan,the comprehensive level of urbanization and ecological environment has been greatly improved from 2006 to 2015,and the speed of urbanization construction was faster than the ecological environment's.Their coupling degree was transformed from the moderate disorder to the primary coordinated development;Their coordination degree has also evolved from the moderate disorder into the primary coordinated development,which was going to the intermediate coordinated development.The coordinated relationship between urbanization and ecological environmental has undergone three modes of urbanization damage-simultaneous development-ecological environment lag.It was worth noting that the development mode of "first pollution and post-treatment" in Sichuan and the stress of ecological environment began to show obviously.The development of urbanization should conform to the restriction of ecological environment and put forward to the construction of new urbanization.(2)From the cities of Sichuan,the comprehensive level of urbanization and ecological environment has showed a steady incresing trend from 2006 to 2015,but the regional differences was obvious,which was roughly reduced from the Chengdu plain cities group to the surroding;The changes of the coupling degree fluctuates greatly,and almost in the antagonistic period;the Coupled coordination degree has transformed from "the moderate disorder class" into "the primary coordination development class",but mostly on "the verge of imbalance";the coordination between urbanization and ecological environment has undergone urbanization damage to the synchronous development.With reference to the evolution of the coupling relationship between urbanization and ecological environment in Sichuan Province,it was necessary to strengthen the ecological environment construction and guard against the lagging city with ecological environment.
