The Spatio-temporal Dynamic Analysis Of Tourists In Hexi Corridor Based On Microblog Data

Nowadays,with the rapid of China’s tourism development,the international tourism is also improving,which makes China’s tourism development into a new period.Hexi corridor,as a key tourism region in Gansu province,has gradually formed a good development pattern and become one of its pillar industries.Even so,tourist attractions are crowded in the peak season,while tourism resources are largely idle in the off-season.The asymmetric distribution of tourists have a great impact on the management of tourist attractions and the development of tourism resources.How to find the dynamic balance for the management of tourism resources in the peak season and the low season of tourism is a topic that needs to be studied in depth.So this paper takes the tourism of five cities in Hexi Corridor as the research object,and systematically collected microblog data,integrated by the methods of literature analysis method,time,layered,GIS spatial analysis and other research methods,research data accurate to "day",spatio-temporal analysis of tourists in Hexi Corridor.By analyzing microblog data,the following conclusions: the Hexi Corridor tourists of microblog data from 2016 to 2018,the overall trend is to present the "M" type distribution,which in 2016 and 2017,the number of tourists of microblog are respectively shows the characteristics of the distribution of the "double peak valley",and in 2018,presents the distribution characteristics of the "three peak valley".The seasonal characteristics are obvious.Summer and autumn are the peak seasons of tourism,mainly in May and August;winter and spring are relatively cold,and the tourist flow is significantly reduced;the tourism trough is mainly in December and January.The number of tourists in holidays and festivals is concentrated and unevenly distributed.The annual spatial change characteristics of the number of tourists in Hexi Corridor show the characteristics of aggregation small points and large dispersion in 2016 to the spatial distribution characteristics of patchy,large dispersion and small aggregation in 2018,with obvious grade differentiation.The spatial change characteristics of the number of tourists from low season to high season are the spatial distribution characteristics of "scatter-blockaggregation-scatter-shape".The spatial variation characteristics of the number of tourists during holidays and festivals show the spatial distribution characteristics of "multi-core and zonal distribution".Finally,through the conclusion analysis,in the three years from 2016 to 2018,the number of tourists of microblog in Hexi Corridor increased year by year,and the growth and proportion of tourists in the five cities were unbalanced,based on the results of the study,the problems of the spatial and temporal distribution of the number of tourists in Hexi Corridor are summarized,and the corresponding optimization strategies are put forward.To play the role of price leverage,the peak node passenger flow regulation;to strengthen and improve the real-time monitoring system of the number of tourists in scenic spots,and to regulate the dynamic space-time of tourists;play to the location advantage,realize the core to the edge of the diffusion.
