Research On The Identification And Spatio-Temporal Evolution Of The Non-Coordinated Coupling Of Tourism-Urbanization-Ecological Environment In The Yangtze River Economic Belt

Tourism is a green and efficient industry that has made outstanding contributions to regional economic development and has become a new engine for local governments to promote national economic development and urbanization.In recent years,the process of urbanization in our country has been accelerating.The growth of urban population and the prosperity of urban economy have injected vitality into the development of tourism.Both are inseparable from the ecological environment in the development process,and a good ecological environment provides basic support for their development.Tourism,urbanization and ecological environment are dynamic relationships that promote and coerce each other.In the context of green development,determining the non-coordinated coupling characteristics of the three is conducive to achieving the coordinated and orderly development of the three.Based on the analysis of the interaction between the three,starting from the perspective of reverse thinking and problem diagnosis,taking 11 provinces(cities)and cities in the Yangtze River Economic Belt as the research objects,constructing an index system and a non-coordinating coupling model through evaluation,Using Arc GIS 10.3 software,the non-coordinated coupling and spatiotemporal evolution characteristics of tourism-urbanization-ecological environment in 11 provinces(cities)from 2005 to 2018 were studied.The main research conclusions are as follows:(1)From 2005 to 2018,the comprehensive evaluation indicators of tourism,urbanization and ecological environment subsystems in 11 provinces(municipalities)of the Yangtze River Economic Belt showed an upward trend year by year.Except for Jiangsu Province,the ecological environment comprehensive evaluation indicators of the remaining 10 provinces(cities)are all higher than those of urbanization and tourism.(2)The tourism,urbanization,and ecological environment systems of the Yangtze River Economic Belt have a high degree of coupling.Jiangsu,Zhejiang and Shanghai are already in a highly coupled stage.The remaining eight provinces(cities)have increased from the running-in period to the highly coupled stage,which shows that the three have a strong interaction.(3)Jiangsu,Zhejiang and Shanghai have the lowest degree of uncoordinated coupling,and they are in the low-level uncoordinated coupling stage.The remaining 8 provinces(cities)are in the stage of confrontational uncoordinated linkage;Guizhou has the highest uncoordinated coupling index.The level of uncoordinated coupling between the eastern and central regions is in a leading position;the lagging characteristics of the western region are in a leading position.The non-coordination characteristics of the county and city levels are more prominent.(4)The constraints of the coordinated coupling of tourism-urbanization--eco-environment system are different.Except Zhejiang,the other 10 provinces and cities all show the lag of tourism,and Zhejiang,Chongqing,Yunnan,and Guizhou show the lag of urbanization.In response to these constraints,suggestions for the coordinated development of tourism,urbanization,and the ecological environment in the Yangtze River Economic Zone were put forward.Scientifically advance the process of urbanization and improve the quality of urbanization development.Develop regional tourism resources and create distinctive tourism brands.Break through the barriers of administrative divisions and promote the development of regional integration.
