Study On The Characteristics And Flow Patterns Of Guangxi Tourism Flow Network Based On GIS

With the rapid development of China's economy,tourism has gradually become an indispensable part of people's life,and tourism flow,as a basic research problem of tourism geography,has been a research hotspot of tourism scholars.It is of great significance for optimizing the distribution of tourism resources and developing the tourism industry in guangxi by analyzing the characteristics and rules of tourism flow scientifically.Guangxi was selected as the research area,the spatial location information and related attribute information of Guangxi tourism flow are extracted through the data mining of tourists' travel itinerary on the Internet,and based on this data,from micro to macro perspective,the matrix of tourist flow relations at three levels among scenic spots,between each county nodes and between each city node are constructed respectively,three tourism flow networks composed of different nodes are obtained: the tourism flow network composed of scenic spots,the tourism flow network composed of counties and districts,and the tourism flow network composed of local cities,and then,guangxi tourism flow network node database and tourism flow path database had been constructed,and in different scale space,the overall and local characteristics of guangxi tourism flow network are studied,by using GIS spatial analysis method and social network analysis method,this paper studied the node characteristics,overall characteristics and local characteristics of guangxi tourism flow network at different levels,analyzes the flow rules and spatial distribution pattern of guangxi tourism flow network,and finally extracts the flow characteristics of guangxi tourism flow network.The research findings are as follows:(1)The distribution of tourism flow network in guangxi is unbalanced,showing the characteristics of small regional concentration and large regional dispersion;(2)The nodes of guangxi tourism flow network have obvious stratification characteristics,which can be divided into five levels according to their centrality: core node,sub-core node,general core node,general node and edge node;(3)Distance has an important influence on the mutual flow of network nodes;(4)The network has obvious regional agglomeration.There are two large agglomeration areas in guilin city and beihai city,and two small agglomeration areas in yangshuo county and haicheng district.The small agglomeration area is located in the interior of the large agglomeration area;(5)The flow scope of guangxi tourism flow network is mostly prefecture-level cities.Except yangshuo county and haicheng district,there is little flow within the county.At the same time,the interaction between the cities is weak and the flow frequency is low;(6)The flow patterns of tourism flow network at different levels and spatial scales have strong similarities.
