自助旅游流网络结构研究，是旅游研究的重要内容。本研究基于徐州市的旅游UGC数据，构建旅游节点旅游流网络，运用社会网络分析法，从描述性特征、中心度、结构洞等方面探讨徐州市自助旅游流网络结构特征。主要结论如下：（1）徐州市节点类型丰富，旅游线路出游时间以1—3天短程旅游为主，平均节点数为4.21；（2）徐州博物馆、宝莲寺、云龙湖、龟山汉墓及云龙山为门户目的地节点；（3）整体网络密度低，不同节点在徐州市旅游网络中的地位不同，云龙湖、回龙窝、户部山、宝莲寺、徐州博物馆及云龙山结构洞优势明显。

The study of the network structure of self-service tourism flow is an important aspect of tourism research. Based on the tourism UGC data of Xuzhou City, a tourism node tourism flow network is constructed, and social network analysis is used to explore the structural characteristics of Xuzhou City’s self-service tourism flow network from the aspects of descriptive features, centrality, structural holes. The main conclusions are as follows: (1) Xuzhou City has a rich variety of node types, with tourism routes mainly taking 1-3 days for short distance travel, with an average node number of 4.21; (2) Xuzhou Museum, Baolian Temple, Yunlong Lake, Guishan Han Tomb, Yunlong Mountain Portal Destination Node; (3) The overall network density is low, and different nodes have different positions in the tourism network of Xuzhou City. Yunlong Lake, Huilongwo, Hubu Mountain, Baolian Temple, Xuzhou Museum, and Yunlong Mountain have obvious advantages in structural caves.
