中文摘要：

测度旅游流空间集聚与扩散的常规方法需要旅游流流向数据，这类数据获取困难且可信度难以保证，空间数据分析是缓解该难题的可选方法。1999--2011年湖南地级旅游流空间集聚的探索性分析表明，旅游流在近10年来显著地向长株潭地区集聚并以其为中心向周边地区扩散，但湘西地区接受扩散效应的能力还比较弱；高速公路、高速铁路和空中交通网络对旅游流集聚与扩散的贡献度非常大。因此，湖南需要从3个方面着力优化大湘西快速交通网络，充分利用旅游流的空间扩散效应，在旅游资源富集的大湘西地区形成旅游产业集群。

英文摘要：

Conventional research methods for tourist flow spatial agglomeration needs to use the direction data of tourist flow, such data is difficult to access and hard to guarantee its credibility. Spatial econometric approach is an optional instrument since it overcomes the data challenges above. An exploratory spatial data analysis of regional tourist flow in 1999--2011 showed that, Hunan tourist flow dramatically concentrate and diffuse within Chang-Zhu- Tan area in recent decades, but Xiangxi area is still weak in accepting this kind of diffusion effect. Analysis shows that, the highway, railway and air transportation network contributes large to the agglomeration and diffusion of tourist flow. Therefore, Hunan needs this three methods to optimize Xiangxi rapid transit network, make full use of the diffusion effect of space tourism flow, and to shape a tourism industry cluster in Xiangxi area.
