Research On The Evolution Of Urban Tourism Flow Network Structure Based On Tourism Digital Footprint

Tourism flow is the basis of tourism development and one of the important concepts in tourism geography.With the continuous development of tourism.Tourism economy is especially active,city area as the core hub of regional tourism development process,gathering the quality of the main resources and tourist attractions,its spatial distribution and the rationality of the design of circuit directly affects the tourists experience.How to understand the pattern and mechanism of tourism flow in the city scientifically is particularly important.At the same time,with the popularity of mobile Internet and the rise of social networks,tourists have generated a large number of digital footprints such as travel notes,comments,travel guides,etc.The arrival of the new geographic information era provides a new technical support and method for tourism flow research.At present,the domestic and foreign related research mainly focuses on static tourism flow and qualitative analysis,and the quantitative dynamic research needs to be strengthened.As one of the core cities of the Yangtze river economic zone,Wuhan is rich in tourism resources and the relatively perfect city function,tourism industry structure optimized constantly in recent years,the city tourism image transmission,but every holiday explosive growth of tourism flow part reflects the city tourism route planning and integrated attractions irrationality,city tourism development contradictions in the process of growing,restricting its further development.Based on domestic individual tourist flow in Wuhan city as the research object,through the locomotive automatic crawl trip and where network related network travel tourists digital footprint,using the theory of social network construction of Wuhan tourism flow network structure of evaluation index system,the overall tourism flow network structure in Wuhan city in recent years and discusses the spatial distribution form,and in 2007,2011,2015,2019 four time node based on the viewpoint of dynamic,explore domestic free line of tourist flow network structure in Wuhan city space-time evolution characteristics,and induces the main factors influencing the tourist flow network structure changes.Finally,some Suggestions are put forward from three aspects: regional scenic spot cooperation,tourism route planning and online marketing.The main conclusions of this study are as flows:(1)The tourist attractions in Wuhan are distributed in a quadrilateral pattern with the main urban area along the river as the center,and the high-flow paths are distributed in a quadrilateral pattern with yellow crane tower,Hankou river bank,east lake and Wuhan university as the break point.The overall tourism flow network structure of Wuhan city is loose and unbalanced,the network density is only 8.6%,and the centrality of each node fluctuates greatly.Wuhan university,east lake,yellow crane tower,Hubu lane,Yangtze river bridge and JiangHan road pedestrian street are nodes with high centrality,which are at the core of the network structure.The travel flow under different traffic control presents different network characteristics.As the traffic threshold increases,the average traffic gradually increases,and the number of nodes and paths decreases.(2)Compared with 2007,the network density dropped to 0.07 in 2019,the links between the various scenic spots were loose,lack of linkage and grade complementarity,tourism nodes were increasing,showing the distribution characteristics of "large dispersion,small agglomeration",polarization characteristics are more obvious,tourism flow structure is loose,there are obvious stratification phenomenon.In recent years,with the development of tourism,a large number of new tourist nodes have been produced,and the frequency of tourists visiting has gradually increased.The high flow path presents a pentagonal distribution with East Lake,Hubei Provincial Museum,Wuhan University,Hubu Lane and Jiqing Street cluster as the endpoints.(3)The increase of cultural and commercial blocks and modern urban scenic spots has changed the network structure of traditional tourist flows and the distribution pattern of scenic spots,and the city's gradually perfect transportation system has promoted the linkage development of various marginal scenic spots.In the overall distribution,the core regional linkage coefficient is increasing,and the network structure of tourism flow has obvious junction Structure stratification,mainly by the core node to connect each other,the core area to the edge area trickle effect is limited,the edge area tourism node is in the subordinate position,in the future needs to strengthen own tourism product upgrade,at the same time strengthens the connection with the peripheral core node.
