基于分形理论的农业旅游空间结构优化研究——以广西国家级农业旅游示范点为例

基于分形理论关联维数的应用探讨，利用广西国家级农业旅游示范点为研究样本，分析了广西国家级农业旅游示范点系统的空间结构特征．结果表明。广西国家级农业旅游示范点空间结构具有分形特征。其自组织演化在空间结构方面具有优化趋势，其空间结构特征与交通因素密切相关，表现出按照一定的交通轴线发生联系．研究同时从构建完善农业旅游中心地等级体系、优化系统内部交通网络结构、农业旅游示范点建设以及农业旅游示范点的线路组合等方面提出了广西国家级农业旅游示范点空间结构优化的建议．

Research on the Optimization in Agro-tourism Spatial Structure Based on the Fractal Theory --.The Case of Guangxi National Agro-tourism Demonstration Sites

Based on the application of Correlation Dimension in Fractal Theory, the paper analyzes the spatial structure features of tourism industry system of Guangxl national agro-tourism demonstration sites by taking them as research samples. The results show that the spatial structure of Guangxi national agro-tourism demonstration sites has the fractal feature, their self-organizing evolution in spatial structure has optimization trends, and their features in spatial structure are closely related to transportation, which exhibits generating contact according to certain transport axis. The research also puts forwards the suggestions on optimization in systematic spatial structure of Guangxi national agro-tourism demonstration sites from the following aspects, such as building a complete hierarchy system of agro-tourism center, optimizing the structure of internal transportation network, the construction of agro-tourism demonstration sites and the line combinations in the system, etc.
