Analysis And Optimization Of Tourism Spatial Structure Of Chongqing Under The Background Of High-speed Railway Network

China is in the high speed rail network era and the era of two new times in the era of mass tourism.As one of the six elements of tourism,traffic is the supporting condition and basic guarantee of tourism.At the same time,the high-speed railway network has been perfected,and it also affects and promotes the development of tourism.As the hub of traffic in Western China,Chongqing city is also being built and perfected,and the spatial structure of tourism in Chongqing is also changing under the background of high speed rail network.It is of great significance to study the present situation of the tourism space structure in Chongqing and how the high speed rail network affects it.It is of great significance to guide the tourism industry in Chongqing to conform to the trend of the times and to guide the rational layout of the spatial structure of the tourism in Chongqing.This study is divided into three parts: basic analysis,empirical research and research conclusion.The first part is the basic analysis.This part includes the first chapter,the introduction and the second chapter,the current research situation at home and abroad.This part mainly carries on the background analysis,the literature review,the related concept definition and the related support theory elaboration and so on.The second part is an empirical study,and it is also the most important part of this study,including the third chapter,the Chongqing high speed rail network and the Chongqing tourism space structure analysis and the fourth chapter,the impact of the high speed rail network on the spatial structure of Chongqing tourism.Through the analysis of the Chongqing tourism space structure and the status and evolution of Chongqing high speed rail network,this part makes a quantitative study on the impact of Chongqing high speed rail network on Chongqing tourism spatial structure from three dimensions of point,line and surface.The third part is the conclusion of the study,including the fifth chapter,the optimization strategy and the sixth chapter of Chongqing tourism spatial structure under the background of high-speed rail network.This part puts forward the optimization strategy of Chongqing tourism space structure under the background of high speed rail network and the conclusions and shortcomings of this study,as well as the prospect of future related research.The main conclusions are as follows:In the study of tourism nodes,the distribution of tourism nodes in Chongqing has some problems of uneven distribution.Tourism resources present a state of agglomeration and distribution,and the service facilities of tourist reception have obvious non equilibrium characteristics.The impact of high-speed rail network on tourism nodes has advantages and disadvantages.On the one hand,the attraction of tourist cities will be enhanced,and the polarization and diffusion effect of regional tourism core cities is expanded;on the other hand,the reception pressure of tourism service facilities and the environmental bearing pressure of tourist attractions are aggravated.Under the background of high speed rail network,this paper puts forward the optimization strategy of Chongqing tourism attraction Center reconstruction,special tourism products along the high speed railway,and the attraction of tourist cities,as well as the increase of tourism reception facilities and the improvement of tourism service quality in Chongqing.In the study of the axis of tourism.The tourist routes of Chongqing are characterized by four seasons distribution along the backbone traffic lines.There are only four excellent tourist routes in four seasons.The overall connectivity of Chongqing tourism traffic network is good,the circuit is good,the connectivity is at the middle level,and the space distance accessibility of most of the tourist nodes is better.The time accessibility of most tourist nodes is good,the range of equal time circle within 1h reaches 85.47%,and the spatial distribution of isochronous space presents "point axis progressive" space structure..The impact of the high speed rail network on the Chongqing tourism axis is reflected in the "rice" type high speed rail network which makes the overall accessibility of the city of Chongqing obviously improved.The whole city of Chongqing is within the scope of the one day communication circle,and it also obviously improves the accessibility of the external traffic in Chongqing.In the background of high speed rail network,it is proposed to improve the tourism line along the high speed rail line,improve the external and internal tourism transportation system,and build the tourism axis optimization strategy of "fast forward roaming" through the opening of tourism direct to high speed rail,tourist direct train and the construction of water,land and air three-dimensional tourism traffic network.In the study of tourism area,Chongqing tourism area by the distribution of tourism resources,the economic development level of the city and traffic conditions has always been "one circle and two wings regions";tourist market at home and abroad are subject to distance constraints,the formation of three tourist market.The impact of high-speed rail network on Chongqing tourism area includes strengthening the cooperation and competition relationship between regional tourism and expanding the tourist market of Chongqing.Under the background of high speed rail network,we put forward the strategy of establishing a whole domain tourism demonstration area and strengthening the tourism cooperation between regions and regions,and building a new tourism domain optimization strategy of "large scope cooperation,multi industry integration and whole society participation" in the new pattern of Chongqing whole area tourism.
