河南省城镇体系空间结构分形特征分析

选取分形理论中的聚集维数和关联维数计算分析了河南省城镇体系空间结构。结果显示,河南省的城镇体系空间结构具有分形特征,中心城市的影响力明显,但相对于其他地区首位城市地位有一定差距,大致呈现弱极多核心态势。各城镇之间联系紧密程度一般,通达性有明显提升。总体来说,河南省城镇规模较为均衡,城镇联系不够紧密,城镇体系功能尚未能充分发挥。

Study on Fractal Characteristics of Urban Spatial Structure in Henan Province

By means of the theory of multi- fractals,this paper was devoted to studying the spatial structure of Henan urban systems,the authors calculated the values of the spatial correlation dimension and cluster dimension. The results showed that Henan urban system with fractal character was in contrast to other district with a remarkable central city influence of province urban system,but still had a certain disparity comparing with other dis- tricts＇ first city. With common links between each urban and accessibility was obviously improved.To sum up,Henan was a province with a balanced urban scale,urban did not tie too much with each other,the function of urban system had not brought out completely.
