Classification and Spatial Distribution Characteristics of Tourist Attractions in Shanxi Province Based on POI Data

By combining big data with traditional geographic information system and taking Point of Interest (POI) data of Shanxi tourist attractions as the research object, we firstly classified the data, and then analyzed their overall spatial distribution pattern and distribution direction, as well as their spatial distribution characteristics of specific cities. Results showed that the overall distribution pattern of tourist scenic spots in Shanxi presents an agglomeration characteristic in Jinzhong district, but the agglomeration pattern and degree of the tourist scenic spots in different district were different. Geographical landscape tourist attractions mainly concentrated in central, southeast and northeast districts of Shanxi. Water scenic spots concentrated in central, south and northeast districts with an axial zonal distribution; Biological landscape tourist attractions showed a ‘diamond’ agglomeration pattern; relics tourist attractions were mostly distributed in northern, and southeastern Shanxi; Construction and facilities of tourist attractions presented agglomeration characteristics of triangular shape; The entertainment and shopping tourist attractions were evenly distributed in the whole province. The spatial distribution direction of tourist scenic spots was consistent with the regional shape of Shanxi Province. Except for no directionality and centrality of the distribution of entertainment and shopping tourist scenic spots were found, other types of the tourist scenic spots have different degree of agglomeration characteristics. The analysis of the spatial pattern of tourist attractions for all prefecture-level cities showed that water scenery scenic spots were evenly distributed among the cities. The hot spots of landscape and architectural facilities appeared in Yangquan City, while the cold spots appeared in Jincheng City, but the degree of agglomeration was small. The hot spot area of biological landscape tourist attractions is located in Changzhi City, while the cold spot area is located in Linfen City and Yuncheng City, with a high degree of agglomeration. In addition, the factors that influence the spatial distribution of scenic spots were qualitatively analyzed from two aspects of physical geography and human society.
