| With the increase of national income,cross-regional tourism is emerging,and the development of regional tourism is accelerating.There are spatial differences in tourism because of the various conditions of tourism resource endowment,traffic location,tourism reception service and so on.The scientific and reasonable tourism spatial structure is conducive to the development of regional characteristics and advantages and the healthy development of regional tourism.Chengdu-Chongqing Economic Circle is located in the upper reaches of the Yangtze River.The cities are geographically adjacent,close to each other,with superior resource endowment.It has a good foundation for tourism.The outline of the plan for the construction of Chengdu-Chongqing Economic Circle clearly puts forward the goal of building a world-class leisure and tourism resort.The tourism industry in the economic circle will release greater potential,and the development of tourism can also feed the construction of the economic circle.However,with the rapid economic growth,the tourism market competition within it is becoming more and more fierce.The tourism resources and traffic of each city are different in space,and the tourism economy within the economic circle presents an unbalanced development trend,limiting the further development of the tourism industry in the economic circle.Therefore,by analyzing the present situation of tourism spatial structure of Chengdu-Chongqing Economic Circle,identifying its existing problems and building a reasonable tourism spatial structure is of great significance to promote the development of tourism and help the construction of world-class leisure tourism resorts.Firstly,this paper sorts out the literature on tourism spatial structure and the tourism spatial structure of Chengdu-Chongqing Economic Circle,and defines the concepts of economic circle and tourism spatial structure.Then,this paper combs and summarizes the growth pole theory,point-axis theory and other related theories of tourism spatial structure.On this basis,this paper makes a theoretical analysis on the rationalization of tourism spatial structure from four aspects: the connotation of tourism spatial rationalization,the characteristics of tourism spatial rationalization,the mode of tourism spatial rationalization,and the particularity of tourism spatial rationalization with dual core structure.The characteristics of tourism space rationalization are mainly analyzed from tourism nodes,tourism development axis and tourism groups.The theoretical research lays the foundation for the research on the current situation of tourism spatial structure of Chengdu-Chongqing Economic Circle.Secondly,it analyzes the supporting background of the tourism spatial structure of the Chengdu-Chongqing Economic Circle,and analyzes the development overview,tourism resources,tourism transportation,tourism reception services,tourism economic status and spatial distribution characteristics of the Chengdu-Chongqing Economic Circle in a qualitative and quantitative way.On this basis,this paper analyzes the current situation of tourism spatial structure of Chengdu-Chongqing Economic Circle from three aspects: tourism nodes,tourism development axis and tourism groups.First,the comprehensive level of tourism nodes is measured from four aspects: tourism resources,tourism reception service,traffic superiority and tourism economic development,and then determine the level of tourism nodes.Second,through the tourism economic connection intensity model,the tourism economic connection between each tourism node is clarified,and the foundation of the formation of the tourism development axis is determined.Then,the social network analysis method is adopted to determine the tourism development axis.Third,after clarifying the current situation of point axis,the current composition of tourism groups in Chengdu-Chongqing Economic Circle is determined through agglomeration subgroup analysis.Through the above research on the status quo of the tourism spatial structure of Chengdu-Chongqing Economic Circle,it identifies the problems including :(1)the improvement of the tourism node level system;(2)the promotion of the tourism development axis level;(3)the strengthening of the connection of tourism groups.Finally,in view of the existing problems,the optimization suggestions of constructing the tourism spatial structure network model of Chengdu-Chongqing Economic Circle are put forward from three aspects of :tourism node,tourism axis and tourism group,mainly including :(1)Give play to the driving role of dual cores,consolidate the development foundation of low-level tourism nodes;(2)Improve the existing axis level,improve the construction of tourism transportation;(3)Do a good job in tourism top-level design,deepen the cooperation within the group,strengthen the contact between groups. |
