Study On Spatial Behavior Pattern Of Tourism In Scenic Spots Based On Trajectory Data

In recent years,with the rapid development of mobile Internet and social networks,more and more tourists in Weibo,travel social networking sites and other online space to voluntarily release the text related to personal travel behavior and tourism perception experience.Reviews,photos and other crowdsourcing tourism information.Tourism and tourism geography scholars carried out research based on such data sources of tourism place name heat,geographical names co-occurrence relationship,landscape attention,travel space model.Research on tourists' spatial and temporal behavior,urban recreation space,tourism perception and destination choice.Compared with the crowdsourcing tourism information of location micro-blog,location photos and travel notes,the GPS trajectory not only completely records the travellers' travel path and other spatial information,but also completely records the time attributes of the trajectories,which can embody a continuous travel time and space process.For tourism science,especially for tourism geography,GPS trajectory can not only be used to study tourists' tourism behavior,but also can be used to excavate tourists' perception and evaluation in multiple time and space scales.And then in-depth study the attention of tourists.Because of the important value of GPS trajectory to the study of tourism behavior and tourism geography,this paper designs a transformation method of GPS locus information type,which can not obviously reduce the amount of track information.The GPS trajectory described by vector data structure is transformed into the spatial unit of raster data structure description,which forms a data form which is easier to carry out spatial statistics and analysis mining by means of GIS and other tools.This paper takes Jiuzhai Valley as an example and chooses GPS trajectory data recorded by mobile device and uploaded through Internet during tour process as the research sample and the moving speed of GPS trajectory connotation.The basic characteristics of tourism behavior,such as velocity fluctuation characteristics,moving state duration,data outliers and so on,are taken as the basis of the classification of tourism behavior patterns,and the concept model of GPS trajectory rasterization is put forward.This paper designs a spatial model representation method of tourism behavior based on GPS trajectory rasterization,which can not only distinguish three different types of tourism behavior spatial patterns: sightseeing,rest and ride.Moreover,it can describe the dominant behavior pattern of any location in tourism space,and can solve the detailed quantitative study of tourism space-time behavior and tourism geographical pattern and process.The empirical research on Jiuzhai Valley proves that GPS trajectories can characterize the spatial distribution patterns of different types of tourists under multiple temporal and spatial scales clearly.Jiuzhai Valley tourist's behavior characteristics of the spatial distribution model are obvious.From the perspective of the entire tourist space,the sightseeing tour is distributed in the Shuzheng Valley and the Rize Valley concentrated and continuously.The typical landscape of Zechawa Valley is only Colorful Pond,Lang Lake.From the spatial scale of a single landscape line,the Landscape section of "Heye Village-Tiger Lake" in Shuzheng Valley and "Mirror Lake-Pearl Shoal-Five Flower Lake-Arrow Bamboo Lake" section of Rize Valley are concentrated in tourism sightseeing the scenic section.From the spatial scale of a single landscape,the Shuzheng Lakes,Nuorilang Lakes,Pearl Shoal,Five Flower Lake,Panda Lake and Arrow Bamboo Lake are sightseeing attractions.The results of the rasterized tourist's behavior spatial model are basically consistent with those of other data sources,but the descriptions are more abundant and the spatio-temporal accuracy is higher.The method can provide support for the research of space-time behavior in tourism and improve the sophistication of tourism geography research.The result of case calculation can provide reference for the planning and management of tourism destination,especially the sightseeing route and the scenic guide design.
