Study On The Tourism Spatial Structure Of Guizhou Province Under The Influence Of High-speed Railway

Since the end of 2014,Guizhou Province has opened the Guiguang high-speed railway,the Shanghai-Kunming high-speed railway and the high-speed railway.The paper uses the "point-axis" theory and the "core-edge" theory to analyze the influencing factors of the tourism spatial structure and the impact mechanism of the high-speed rail.The basic characteristics of the two high-speed railways in Guiguang and Hukun,the paper comprehensively uses the first degree and the tourism economic linkage strength model to qualitatively and quantitatively analyze the tourism spatial structure of Guizhou Province,from the three aspects of tourism center of gravity change,center change and tourism connection intensity.The analysis of the important influence of high-speed rail on Guizhou and the change of Guizhou’s tourism spatial structure under the influence of high-speed rail has changed the structure of tourism spatial structure in Guizhou,and combined with ArcGIS mapping software,the spatial structure of tourism in Guizhou Province has been changed in the period of2012-2017.Out,the development of high-speed rail will change the function and status of the node cities along the high-speed rail,which will lead to changes in the tourism spatial structure of Guizhou Province.Finally,it predicts the trend of future tourism spatial structure change in Guizhou Province under the influence of high-speed rail,and puts forward reasonable suggestions for the future tourism development of Guizhou Province to optimize the regional tourism spatial structure of Guizhou Province.The results show that the focus of tourism distribution,the first degree and the interaction intensity of tourism space in each city have changed significantly in 2015 and 2016.These two time nodes are consistent with the opening time of Guizhou high-speed railway,so it can It shows that under the influence of high-speed railway,the tourism spatial structure of Guizhou Province has indeed changed,and theinfluence of high-speed railway plays a key role.The high-speed railway has weakened the centrality of Guiyang in the core area.The first degree of Guiyang City is declining,and the diffusion of marginal areas is strengthened,so that the tourism space structure of the whole region is developing in a balanced direction.It is predicted that the scope of the core area of Guiyang will increase in 2020,and the range of tourism space radiated from the core to the marginal areas will expand significantly,and the center of gravity will shift to the southeast.Gannan and Southeastern Guizhou will become The core of secondary tourism development.According to the forecast,it is suggested that Guizhou Province should make rational use of the advantages of tourism resources,speed up the construction of transportation networks,coordinate the investment of regional tourism resources,and strengthen inter-city tourism cooperation.
