| Influenced by the " space-time compression" effect of high-speed rail,the traffic accessibility and tourism spatial structure of urban tourist destinations in China are undergoing significant changes.Tourism economic connection is the external manifestation of the flow of tourism industry elements,which can reflect the spatial attribute of tourism economic activities and the interrelationship between the cities'destinations in the spatial network,and reveal the characteristics and laws of regional tourism spatial structure to a certain extent.Therefore,deepening the understanding of tourism economic connection has basic theoretical significance for the coordinated and integrated development of regional tourism and practical significance.Beijing Tianjin Hebei region is one of the regions with the earliest high-speed railway construction and the fastest development in China.The dense high-speed railway network of "four horizontal,four vertical and one ring" is forming.With the continuous improvement of high-speed rail network,the cooperation in tourism market development,tourism product innovation and other aspects among cities in Beijing Tianjin Hebei region will continue to deepen,and the flow speed,intensity and scope of tourism elements in the spatial network will be faster,stronger and wider.Under the background that the coordinated development of Beijing-Tianjin-Hebei area has become a national strategy,what impact will the high-speed rail construction have on the spatial structure of regional tourism economic ties?Will the spatial structure of tourism in Beijing-Tianjin-Hebei area have a different evolution trend in the different stages of the development of high-speed rail network?Under the social background of high-speed flow of tourism elements,does Beijing,Tianjin and Hebei need to change their thinking to realize the spatial pattern of balance and decentralization?Based on the above questions,this study,according to the development process of Beijing-Tianjin-Hebei high-speed railway network,constructs three ideal scenarios:no high-speed railway,link of main lines and network development.Based on the accessibility model,gravity model and social network analysis,it simulates the spatial structure of Beijing-Tianjin-Hebei accessibility and Tourism economic relations and discusses its evolution characteristics,in order to reveal the high-speed railway network construction of each city destination The changes of roles and functions in the process of design provide scientific basis for the optimization of tourism spatial structure in Beijing,Tianjin and Hebei.Based on spatial interaction theory,social network theory,core edge theory,point axis theory,qualitative analysis,modified gravity model,accessibility model,network density,centrality analysis,agglomerated subgroup analysis and core edge model,this study mainly achieves the following research purposes:(1)analysis of traffic accessibility performance in Beijing,Tianjin and Hebei under high-speed rail network Change characteristics and laws;(2)reveal the strength,size,network structure and characteristics of the tourism economic ties in Beijing,Tianjin and Hebei,as well as the evolution laws of the spatial structure in different stages of the high-speed railway network construction;(3)under the background of high-speed flow of tourism elements,optimize the tourism spatial structure in Beijing,Tianjin and Hebei,and explore the tourism development mode conducive to its integrated development.The research contents of this topic mainly include:(1)combing the domestic and foreign research and theories about the accessibility of high-speed rail,the spatial structure of tourism,the impact of high-speed rail on the spatial structure of tourism;(2)using ArcGIS software to visualize the spatial distribution of accessibility of three simulation situations,namely,no high-speed rail,trunk connection and network formation,and analyzing the change rules of the regional traffic accessibility of Beijing,Tianjin and Hebei(3)based on the "relationship" data of 13 prefecture level cities in Beijing,Tianjin and Hebei,calculate the intensity and total amount of tourism economic ties among cities,and further analyze the overall network structure,node function and position,and group structure of tourism economic ties in Beijing,Tianjin and Hebei under the three scenarios of high-speed rail development by using the social network analysis method;(4)apply the growth pole theory,point axis theory,and core theory-Based on the edge theory,this paper constructs the spatial development mode of tourism economic relations under the background of high-speed rail network,and studies the optimization of the tourism spatial structure of Beijing,Tianjin and Hebei.The research conclusions of this topic are as follows:(1)high-speed railway mainly affects the change of transportation time cost and urban development potential,and the improvement of location conditions of node cities is not significant.(2)The accessibility spatial effect and tourism spatial effect in the process of high-speed rail network are similar;(3)under the influence of high-speed rail network,the tourism economic relationship between cities in Beijing Tianjin Hebei region is increasingly close,and the tourism spatial structure changes from "single core agglomeration","dual core leading"to "two core driven,multi-point growth";4)Beijing and Tianjin are two adjacent cities The city has the dual roles of "leader" and "middleman",and the intermediary capacity of Baoding and Shijiazhuang has been strengthened;(5)under the high-speed rail network,the tourism economic relationship between Beijing,Tianjin and Hebei has developed in a cluster mode,which is shown as "double C" The core edge hierarchical structure is obvious and relatively stable;(6)the "2+4" growth pole development mode,"1+2+3"axis development mode and two key development tourism areas are proposed.The innovation of this study lies in:(1)considering the stage of high-speed rail construction(high-speed rail network degree),this study makes a double comparison between the regional horizontal and the stage vertical of high-speed rail tourism impact,which to some extent makes up for the limitations of the previous research only in the period of trunk line connection or network formation;(2)the double development of coordinated development and high-speed rail network in Beijing,Tianjin and Hebei Under the background,it constructs the growth pole development mode,axis development mode and tourism area development mode from three aspects of node,axis and area,which provides effective suggestions for the optimization and upgrading of tourism spatial structure in Beijing Tianjin Hebei region. |
