A Calculation Method Of Scenic Heat And Tourists Spatial-temporal Transfer Mode Represented By Location Photos

The development of social media has promoted the popularization of spatial information and realized data sharing.Users are not only users of spatial data,but also producers of spatial data.Location photos can reflect the things that users are interested in traveling or living.The user uploads the photos to the social network platform and allows other users to download and use,and then realize data sharing.Location photos include abundant attribute information,and have the advantages of lower data acquisition cost,larger data volume,faster update,etc.The photos taken by tourists during the trip can reflect the hot spots of the scenic spots and the tourists' routes,and are widely used in disciplines such as tourism and geography.To reflect the real tour path of tourists,this paper designs a tourist route extraction method based on the photos taken by tourists many times at different time periods at same places.The method preserves the photos taken by the same tourist at the same place and at different times.However,for successive photos taken by same tourists at same places,only the first one is taken.After that,mathematical statistics and density analysis were used to analyze the variation characteristics of heat area in the scenic spot.And finally,in order to calculate the spatialtemporal transfer probability of tourists,the point center of directed graph and Markov Chain method are combined to calculate the spatial transfer probability and time transfer probability of the photographed tourists.Taking the small-scale Jiuzhai Valley scenic spot as the case,this paper further divides the scenic area into the attractions,the landscape segment and the landscape line scale,and studies the hot spot distribution in the scenic area and the time-space transfer mode of photographing tourists from multiple time and space scales.The research results show that:(1)As the popular scenic spots of Jiuzhai Valley,the landmarks such as Five Flower Lake,Pearl Shoals Waterfall,Shuzheng Lakes,Nuorilang Waterfall,Five Coloured Pool and Long Lake are all hot in the whole year.Each attraction has the best viewing time.As a whole,the tourists taking photos on the Rize Valley scenic line are mostly concentrated in the morning,while on Zechawa Valley and Shuzheng Valley scenic lines photographed tourists are mostly concentrated in the afternoon.(2)Under the guidance of the scenic area shuttle bus,a spanning transfer mode is formed.The spanning transference mode occurs mostly in the landscape with a long distance from the landscape or between different landscapes.The landscape is mostly located at the end point or junction of the scenic line.Within the scenic line,the probability of space transfer between landscapes is larger,and the gap of time transfer peak is smaller.Between the landscapes,the probability of spatial transition is smaller,and the gap of time transfer peak is larger.(3)Tourists who mainly walk on the boardwalk are easy to form the adjacent transfer mode.The adjacent transfer mode mostly appears in the interior of the scenic line,and the distance between landscapes is relatively close.With the increase of the distance between landscapes,the transfer probability of the photographed tourists is decreasing and the gap between time transfer peaks is increasing.The schedule of the tourists who walk on the boardwalk have greater autonomy.Sometimes it forms the agglomeration or divergence transfer modes in the elite landscape or the transfer center of the shuttle bus.(4)From the perspective of tourists' time transfer mode,the single peak dominant landscape is mainly distributed between the primeval forest of Rize Valley landscape line and the Arrow Bamboo Lake,and it is concentrated around 9 o 'clock,while the tourists taking photos in the Mirror Lake and Nuorilang Waterfall section are concentrated at about 13 o 'clock.The landscape dominated by doublet peak is mainly distributed in Double Dragon Lakes and Lying Dragon Lake seascape section of Entrance and Shuzheng Valley.The flat and gentle dominant transfer mode is mainly composed of the Five Flower Lake,Pearl Beach,Long Lake and other iconic attractions,and the transfer time of tourists lasts for a long time.It is feasible to study the heat of scenic spot and the time-space transfer of tourists based on location photos,which provides new ideas for the study of tourists' time-space behavior.The research results can provide reference for tourists to visit the scenic spot and stay time of the scenic spots,and provide decision support for scenic spot managers to guide tourists to visit and arrange shuttle bus.
