其他摘要：Based on the online travel notes released by tourists, using social network analysis, this article analyses the spatial structure characteristics of tourist flow network under the county-level administrative units in Guangxi. The results show that:(1) The density of tourist flow network in Guangxi is sparse, and the tourist flow is dominated by landscape sightseeing tours and coastal holiday tours. (2) Nanning, Guilin, Beihai and Yangshuo are the core nodes of tourism system in Guangxi, which not only have great tourism attraction, but also have strong resource control capabilities. (3) Guangxi tourism presents a significant clustering phenomenon. The tourist flow is extremely uneven. The popularity of scenic spots has an important impact on the node flows. The level of the regional transportation network determines the central position of the node in the network to a large extent.
