基于分形理论的广西城市体系空间结构研究

城市是人口和经济的聚集地,城市体系空间结构具有分形几何特征。将分形理论与中心地理论相结合,通过城市体系的关联维数模型计算出广西城市体系空间结构的分维值,发现广西城市体系的空间分布是具有分形特征,城市体系自组织演化在空间结构方面具有优化趋势,可以强化中心、极化南宁核心地位,重点扶持桂林、柳州、北海三个副中心建设,构建"一枢纽、二港口、三通道、四辐射"大通道体系和点轴面相结合发展的广西城市体系空间结构。

The Research on Guangxi City System Spatial Structure Based on Fractural Theory

City inhabit Theory both people and economy.Its spatial structure involves the fractural features.By combining fractural theory with central geographical theory,the paper makes a model of the interrelated dimensions of Guangxi city system spatial structure.It analyzes the fractural features of Guangxi city system spatinal distribution and generalizes the optimal trend in the process of self-organization evolution.The paper maintains the significance of building a vertieal spatial structure of Guangxi city system which focuses on centralizing Nanjing City,while building three sub-centers such as Guilin,Liuzhou,Beihai.This vertical city structure has a wide verage of pivot,harbour,passageway and radiation.
