中文摘要：

以大南岳旅游圈30个星级乡村旅游地为研究样本，基于GIS空间分析技术，运用平均中心距离、旅游地离散指数、等距离线法、拓扑关系等方法，分析了大南岳旅游圈内乡村旅游地的空间结构特征。结果表明：（1）从距离角度来看，大南岳旅游圈乡村旅游地的平均中心距离在28．15km-46．29km之间，旅游地的等级越高越接近中心地。（2）从分散程度来看，大南岳旅游圈乡村旅游地的空间离散指数在0．2795—0．8393之间，分散程度变化幅度大，且旅游地的等级越高布局越分散。（3）从布局角度来看，大南岳旅游圈乡村旅游地分布不均衡，出现了“一高两次高”的带状分布区。最密集分布区在距离中心45km-50km区域内，两次高分别分布在距离中心15km-20km和55—60km之间，整体分布曲线大致呈“w”状。（4）从交通可达性来看，大南岳旅游圈交通网络连接度处于中下水平，区域内交通可达性较低。基于以上研究结果，为优化大南岳旅游圈乡村旅游地空间布局，提出可行性措施。

英文摘要：

Taking 30 star rural tourism destinations as the research sample, based on GIS spatial analysis technology and using methods of average center distance, tourism destinations dispersion index, equidistance line, the topological relationship, this article analyzed the spatial structure characteristics of rural tourism destinations in Great Nanyue tourism circle. The results show that.. （1） From the perspective of distance, the average center distance of rural tourism destinations between the 28.15km-46.29km in Great Nanyue tourism circle. The higher of tourism destination level, the closer to the center. （2） From the perspective of dispersion degree, spatial dispersion index between 0. 2795 0. 8393 and dispersion degree varied considerably. The higher level of tourism destination, the more disperse of the layout. （3） From the perspective of layout, the rural tourism distribution is not balanced in great Nanyue tourism circle. It distributed ＂one high-two less high＂ belt area. The most dense distribution area is in the 45km-50km region from the center, the two less high areas, respectively, are in the distance between the center of 15km-20km and 55-60km, the overall distribution curve is roughly ＂W＂ shape. （4） From the perspective of traffic accessibility, the traffic network connection degree is in the middle and lower levels, and regional accessibility is low. Based on the above research results, this article put forward the feasible measures for the optimization of rural tourism spatial layout in great Nanyue tourism circle. Key words：great Nanyue tourism circle; rural tourism; spatial structure; structure optimization
