摘　　要：基于2008—2019年Flickr平台内游客上传的带有西安市地理标记的照片数据,运用HDBSCAN算法和社会网络分析法,对西安市的入境旅游热点地区进行提取,并构建入境旅游流网络结构图,对海外游客的时空行为进行探究.结果表明:2008—2011年,入境游客数量稳步上升,2011年之后逐年下降;月度入境游客访问数量呈倒“W”型分布,峰值出现在每年5月和9月.西安市入境旅游流呈“两级分化,城内集聚”的格局,其中城内旅游热点地区分布相对集中,且热度较高;城外、郊区的旅游热点地区吸引力稍显不足,远郊区的旅游热点地区分布虽少,但热度排名整体靠前.西安市入境旅游流网络结构较为紧密,“核心-边缘”结构特征明显,且核心热点地区对边缘热点地区具有一定的带动和辐射作用.各旅游热点地区的度中心性与接近中心性统计结果排序差异不大,核心旅游热点地区的结构优势突出,可进入性高.Based on the geographic marker photo data of Xi'an City from 2008 to 2019 uploaded by foreign tourists on Flickr website,this study uses HDBSCAN algorithm and social network analysis to extract the area of interest(AOI)of inbound tourism in Xi'an City,and constructs the network structure map of inbound tourism flow.The results show that:the number of inbound tourists increased steadily from 2008 to 2011,and decreased year by year after 2011,the monthly number of inbound tourists showed an inverted“W”distribution,with a peak in May and September.The inbound tourism flow in Xi'an City shows a pattern of“two levels of differentiation and agglomeration in the city”.The AOI distribution of tourism in the city is relatively concentrated,the heat is relatively high,but the tourism AOI attraction of the outskirts is slightly insufficient,the tourism AOI distribution of the outer suburbs is less,but the overall heat ranking is at the top.The network structure of inbound tourism flow in Xi'an City is relatively close,its“core-edge”structure is obvious,and the core AOI has a certain driving and radiating effect on the marginal AOI.There is no significant difference between the statistical results of degree centrality and near centrality of each tourism AOI.The structural advantage of core tourism AOI is prominent and the accessibility is high.
