| Transportation is the basic support for the development of t ourism,It is a great significance to understand and explore the mechanism of transportation to tourism development,to optimize the distribution of regional tourism traffic network and to rationally deploy tourism resources.from the perspective of the influence of traf fic accessibility on the spatial behavior of tourist flows,this paper constructs a scenic accessibility measurement model to evaluate the accessibility of scenic spots above grade A in Yunnan province firstly;after that,based on the information of the t ourist bus passenger transport in Yunnan Province,the social network analysis method is used to extract the characteristics of the network structure of the tour flow of the package tour in Yunnan Province;Finally,through the spatial correlation and statistical characteristics,the relationship between the accessibility of scenic spots and the structure characteristics of the tourist flow network is found.Research shows:(1)The external traffic accessibility of the scenic spots above a class A in Yunnan is poor,and the average external traffic accessibility is only 0.547;high scenic external traffic accessibility mainly concentrated in Kunming city and its surrounding counties,Jinghong,Dali,Lijiang,Tengchong,Manshi follow the followingand the rest of the scenic spots outside traffic accessibility is poor,which discrete distribution in all regions of the province.The city transfer of the scenic spots is good,and the average time of city transfer is 0.303 h,and the spatial pattern is discrete equilibrium.The overall level of accessibility in scenic spots is general,there are only 13 scenic spots with excellent traffic accessibility,and most scenic spots are generally low,accounting for about 66.68%.There are significant differences in the level of accessibility in the scenic spots,and the whole cold hot spots are stratified and banded.(2)Yunnan province’s package tour potential is "multi core cluster regional space pattern,Kunming city touris t flow potential is maximum,has 4621066 people,Weixing is the smallest,only has 53 people.The potential spatial distribution of tourist flow is not affected by time scale,the peak season and the off-season period showed a considerable degree of spatial agglomeration.In terms of flow to scale,there were 1302 package tour flows in Yunnan Province in 2017,but only 21 package tour flows have more than 100 thousand people.The flow direction of the package tour is significantly affected by the season.In the peak season,the spatial migration rule of the tourists is basically the same as that of the annual scale,while the off-season season has the trend of transferring to the Northwest Yunnan tourism area.Yunnan province package tour flow average stay for 4.11 days,the longest stay for 17 days,the shortest stay for 1 days,in accordance with the " minimum travel time-ratio law.(3)The overall network density of Yunnan package tour flow is relatively small,and shows the same characteristics in the off-season and peak season,highlighting the uneven development of Yunnan regional tourism market.Network centrality indicators show that: cities with strong outgoing centers are also strongly introverted,and the agglomeration effect of the tourism node is further evidence of the law of regional tourism development in Yunnan province.Through the aggregation subgroup analysis,the nodes of Yunnan package tour network are divided into 4 subgroups of 2 levels,8 subgroups of 3 levels.There are significant differences in the development of regional tourism,and the development and cooperation of tourism resources between cities should be strengthened.(4)the relationship between the accessibility of scenic spots and the network structure of the package tour flow shows that: the a ccessibility of scenic spots has a driving effect on the diffusion of urban tourism,and the accessibility of scenic spots is the basic support of the attraction of regional tourism,but has a weak relationship with the tourism intermediary capacity of the package tour.The impact of tourism resources on the tourism space behavior of package tour is significantly higher than the accessibility of scenic spots.The tourism space behavior of package tour has obvious tourism resource orientation.Therefore,the balanced development of regional tourism must coordinate and coordinate the development of tourism resources and the construction of traffic network. |
