摘要
通过社交图片网站(Flickr)的数据开放接口,借助计算机程序采集、整理了2008—2013年境外旅游者上传的中国入境游相关照片数据,利用这些照片中的地理位置坐标信息,采用DBScan聚类分析方法,计算中国入境游客地理兴趣点(POI),并结合运用数理统计和GIS空间分析方法分析其空间分布特征。结果表明:1我国入境游客POI分布具有显著的空间分异特征,其分布密度呈现由东向西逐渐递减的态势,并已形成"一级中心集聚带、二级中心集聚区、三级点状飞地"的空间格局;2在一级中心集聚带中所包含的三大核心区内部,其入境游客POI分布同样具有空间的异质性和不均衡性;3在入境游POI分布具有高度空间集聚性的同时,在时间序列上的集聚性具有逐步均衡性发展的趋势;4细分客源市场的POI选择不仅具有高集聚性,同时由于选择偏好的差异从而在空间上的集聚差异显著。
Through the open data interface of a famous social photo websites （flickr.com）, this paper first collected and sorted out the photo data of the inbound tourism in China which are uploaded by overseas tourists from 2008 to 2013 by using computer programs. Furthermore, the information of geographical position coordinates involved in these pictures are analyzed by using DBScan clustering analysis method to calculate the geographical points of interest （POI） of the Inbound Tourists to China, and a further statistical analysis with classification was performed. Based on these previous data, the paper made use of GIS spatial analysis methods, trying to figure out the spatial distribution features of the POI, and conducted a comparative analysis on the preferential POI selection of the tourists from different origins. The results show that： 1）The distribution of the POI among the inbound tourists to China has a significant feature of spatial differentiation with gradually decreasing trend from east to west, and has formed a basic spatial pattern of ＂the first- class central belt, the secondary central area, the tertiary dots enclave＂; 2）The first-class central belt contains three core areas, and the inbound tourists＇ POI in each core area also has the characteristics of spatial heterogeneity and imbalance; 4）With the high spatial aggregation of POI distribution in inbound tourism, the time-series clustering has a tendency of gradually balanced development. 3）With the high aggregation of POI in each tourist market, there is also a significant difference involved in the spatial clustering due to the discrepancies in the preference of tourists from various markets. The paper aims to provide a new perspective and analysis method to explore the spatial characteristics of inbound tourism market, and strives to obtain a more accurate and objective understanding of the development status of inbound tourism in China, so as to provide some theoretical references for the sustainable development of inbound t
