基于对分形理论的理解,分析研究了安徽省城镇体的系结构特征,得出安徽城镇体系的存在着分形特征的结论.规模结构方面,区域内人口分布比较均衡,中间位序城市较为发育,首位城市垄断功能相对较弱,小城镇发展不足.空间结构方面,聚集维数反映以芜湖为重心的城镇体系空间分布最为紧凑,蚌埠次之,而合肥最为松散.网格维数和关联维数都表明安徽城镇体系主要是沿线、沿江分布,城镇间空间相互作用不强,网络均衡性还有待于提高.据此提出安徽省城镇体系优化的几点建议.
Based on fraclal theory, the scale struclure and spatial struclure of the urban system of Anhui Province are investigated. From the perspective of scale structure, there is a relatively balanced population distribulion in this area. Cities of intermediate rank are relatively developed while the monopoly of primate cities is relatively weak, and small cities are less developed. From the perspective of spatial structure, the aggregation dimension reflects that the urban system centering around Wuhu City shows a most compact spatial distribution, Bengbu City comes second while Hefei City is relatively loose. At the same time the grid dimension and the correlation dimension shows that the urban system of Anhui Province is mainly along the Yangtse River. That's to say, it develops in a line. As a result, the spatial interactions among cities are not strong and the network balance needs further improvement. In the end,based on the above analysis, some suggestions are put forward.
