Research On The Characteristics Of Urban Self-service Tourism Flow Network Structure Based On Internet Travel Notes

With the development of national economy and the improvement of people's life quality,the tourism industry has presented a promising trend.At present,China has entered the era of mass tourism,and tourism has already become an indispensable part of people's daily life.Tourist flow is a key area of tourism research.And introducing the Social Grid Analysis Method to study the grid structure of tourist flow is a research hotspot in tourist flow.With the constantly advancement of urban tourism,the research on the grid structure of small-scale urban tourist flow is becoming more and more prominent.On the basis of reading and integrating the relevant literature and theoretical achievements at home and abroad,this paper takes the central city Changsha as a research case.And based on the form of self-help traveling,this paper has also collected 917 effective online travel notes from “Mafengwo” official website,which published by free independent travelers traveling in Changsha.Also,via extracting the information of online travel notes,utilizing Arc GIS spatial visualization to express the spatial distributions of tourist groups,quantitatively analyzing the distributions of tourist sources through the geographic concentration index and visitor-attraction radius and using UCINET Software to explore the grid structure characteristics of tourist flow,this paper further analyzes the differences of grid structure characteristics of self-help tourism flow from the perspective of time constraints and then summarizes the influential factors of the formation of self-help tourism flow's grid structure.Finally,it puts forward some recommended measures that can be used to optimize the tourist flow's grid structure.The main conclusions of this paper can be generalized as follows:(1)From the perspective of months,the best times for self-help tourists to visit Changsha are in April and October.In terms of seasons,they are autumn and spring;(2)Guangzhou,Wuhan and Beijing are the three cities with the largest numbers of self-help tourists traveling in Changsha.Guangdong,Hubei and Zhejiang are the main source provinces of Changsha self-help tourists.From the regional perspective,visitors are mainly from North China,East China and South China.Most of the tourists arrive in Changsha by high-speed trains or trains,but self-help tourists from different provinces can choose different modes of transportation to Changsha;(3)The G value of self-help tourists in Changsha is 12.46 and the radius of tourist attraction is 779.34 kilometers,which show that the tourist sources of Changsha self-help tourists are relatively scattered and the tourist market is relatively stable.And most of the source provinces are also located in the radius of tourist attraction;(4)From the perspective of the Node Grid Structure Characteristics,the tourism nodes that involved have significant numerical differences in node centrality and structural hole indicators.There are obvious tourism-node ranking classifications.The core nodes are mainly Orange Island,Taiping Street,Pozi Street,Hunan Provincial Museum,etc.We should continuously improve the driving effect of these core nodes on other nodes.(5)According to the characteristics of the whole grid structure,we can find that the grid density and the center potential number of Changsha self-help tourist flow are relatively low and the grid structure is loose.What' more,the development of self-help tourist flow is unbalanced and the tourism differentiation phenomenon is very obvious;(6)Based on the perspective of time constraints,the average staying duration of Changsha self-service tourists is relatively short,which is 2.96 days.And there is a significant difference in the grid structure characteristics of tourist flow according to their different staying time,especially when the staying durations are 1 day,2-4 days or more than 5 days.(7)The main factors that affect the formation of self-service tourism grid structure in Changsha are the spatial distances of the tourism destination,the level of internal and external traffic accessibilities,the tourism resource endowment,the popularity of tourist attractions and the level of publicity,etc.Finally,combined with the above analysis and the current situation of tourism development in Changsha,optimization suggestions are put forward from five aspects in order to promote the healthy and sustainable development of self-help tourism in Changsha.
