基于分形聚集维数的都市旅游吸引物空间特征研究——以上海徐家汇源景区为例

A Study on the Spatial Structure of Urban Tourism Attractions Based on Fractal Theory:A Case Study of Shanghai Xujiahui Origin

分形聚集维数的测算可以反映景区旅游吸引物系统空间集聚特征,从而为景区吸引物空间结构的优化提供相应的策略。基于旅游大数据视角,将大众点评上的评论数和评分进行加权计算,结合几何中心确定系统重心吸引物,计算整个景区及其分类子系统的集聚分形维数。结果表明:系统整体存在两个无标度区间且都具有集聚特征。历史建筑吸引物系统重心对其他吸引物具有较强的吸附作用;商业中心和文体场馆吸引物围绕系统重心呈双分形集聚式分布;公园绿地吸引物呈离散状态分布。应培养景区中心的商业中心和历史建筑为核心旅游吸引物,推动外围公园绿地和文体场馆类旅游吸引物建设,充分利用重心吸引物空间分布合理规划旅游路线和旅游产品。同时,在系统重心吸引物间建设景观廊道,提高景区内区域旅游的连贯性和通达性。

The clustering of the fractal dimension can be used to measure the agglomeration of the tourism attraction system in Xujiahui Origin Scenic Spot and to make a scientific assessment of the spatial structure of the scenic spot. Based on the tourism mass data perspective,this study weighted the number of reviews and ratings on the public comments,combined with the geometric center to determine the center of gravity of the system and used the fractal theory to calculate the clustering fractal dimension. The research shows that the tourist attraction system has a good double fractal structure as a whole. According to the type,the center of gravity of historical buildings attracts more other attractions; The spatial structure of attraction system of commercial centers and sports venues show obvious bisected distribution around the center of gravity of the system; Tourist attractions were discrete state distribution. It is necessary to cultivate commercial centers and historical buildings as attractions for tourism in the center of the scenic spots so as to promote the construction of tourist attractions in green parks and sports venues in peripheral parks. It＇ s significant to make full use of the spatial distribution of attractions in the center of gravity to plan tourist routes and tourist products reasonably. Landscape corridors should be built to enhance the continuity and accessibility of regional tourism in scenic areas.
