Research On The Temporal And Spatial Behavior Characteristics And Behavior Patterns Of Tourists Based On Geo-tagged Photos

With the development of information age,tourists' behavior activities are more multi-dimensional and complicated.Using the online data generated by tourists on social network platforms with time,space,emotion and other information provides a new perspective to deconstruct the characteristics and mode of tourists' spatiotemporal behavior.As an important channel of Internet communication and an important manifestation of social media data,geo-tagged photos are also regarded as the visual representation of tourists' behavior,attitude and preference,which could truly and objectively reflect the behavior of tourists.Based on the data of Flickr geo-tagged photos in 2009-2018 with computer data mining technology,this paper comprehensively used various analysis methods such as mathematical statistics,DBSCAN density clustering,GIS spatial analysis,Markov transfer probability,data visualization,etc.,took the Yangtze River urban agglomeration as an example,depiced and revealed the time behavior characteristics and changing rules of tourists in the Yangtze River urban agglomeration from time dimension,explored and identified the spatial AOI(areas of interests)and its attribute characteristics of tourists from the spatial dimension.On this basis,the characteristics and patterns of tourists' behavior track were extracted.The main conclusions were as follows:(1)From 2009 to 2018,The geo-tagged photos data displayed that the tourist flow of the Yangtze River urban agglomeration underwent a volatile growth trend.The fractal characteristics of the tourist flow were obvious,and the overall distribution structure was a "double peak and multi-ridge".The tourist flow was seasonally oriented,the peak season was concentrated in April,May,July,September and October,the flat season was March,June,August and November,the low season was from December to February.The tourist flow had little changes on weekdays,grew in a step-like band and reached peak periods on weekends.Tourists were mainly active during the day,and the activities within one day showed a significant "three peaks" pattern,with small peaks formed separately at 10: 00-11: 00 a.m,15:00 p.m,and 20:00 p.m.The average residence time of tourists was 2.46 days,mainly for short stay.(2)Suzhou and Nanjing constitute the main body of tourist flow in the Yangtze River urban agglomeration collectively.There were significant differences in the hierarchy and spatial structure of 48 spatial AOIs(areas of interest)in the YangtzeRiver urban agglomeration,which were characterized by high-level tourist attractions as the main body,modern urban functional areas as the orientation,urban traffic agglomeration as the support,and overlapped with urban historical and cultural space.tourists preferred the traditional AOIs of sightseeing and leisure,modern business,shopping and entertainment.the AOIs were divided by the centrality index value into4 levels: central AOI,sub-central AOI,general AOI,and edge AOI.among all,Humble Administrator's Garden AOI,Confucius Temple AOI,Zhongshan Scenic AOI,Shantang AOI,Xuanwu Lake AOI were the most popular for tourists.(3)The trend of tourists' spatial behavior trajectory was obvious,which generally concentrated in the south of the Yangtze River.There was a dense linear flow between Suzhou and Nanjing tourist AOIs,and radiated the surrounding AOIs,extended a sub-dense flow trajectory line,thus formed a relatively stable "obtuse angle triangle" trajectory flow structure.The spatial behavior trajectories of tourists in the Yangtze River urban agglomeration were divided into 44 types of multi-AOI trajectory and 4 types of single-AOI trajectory.The paths of "A-A","A-B","A-C","B-B","B-C" in 2 AOIs,the paths of "A-A","A-B","A-C","A-D","A-B-C" in 3AOIs,and the paths of "A-A","A-B","A-B-C" in the 4 AOIs were the trajectory flow framework of the Yangtze River urban agglomeration.(4)A majority of tourists were limited to vertical flows within cities,and horizontal flows across cities were not prominent enough,and the path-dependent features were obvious.(1)Under single-AOI travel mode,tourists had clear motivation,and often took a direct route to "airborne" AOI to carry out one-day tour activities,and rarely stayed overnight on the way;(2)The multi-AOI travel mode was more common and complex.In the 2-AOI travel mode,except for some high-frequency mutual flows in central AOIs,the other AOIs were mostly simple-level linear flows,mainly for 1-2 day tour.In the 3-AOI travel mode,tourists took a straight-chain or ring-shaped activity,mainly for 2-3 days;In the 4-AOI travel mode,The path of tourists was weakened by spatial distance restriction,and the combined flow of cross urban AOIs were more significant,mainly for 3-4 days in-depth tour.(5)The choice of tourist behavior trajectory and mode were mainly related to the tourism endowment resources,transportation accessibility,spatial proximity,and economic development level.different tourism behavior modes provided important basis for market positioning,and integral promotion of the Yangtze River urbanagglomeration.In view of the disadvantages of the current tourism behavior mode,the paper suggested that the single-AOI mode could be changed to the "camp-based mode" or "multi-AOI mode",the "simple linear" 2-AOI mode could be changed to "chain or ring mode",and the "straight or circular" 3-AOI or 4-AOI mode shifted to "peripheral radiation mode".
