中原城市群的空间组合特征与整合模式

城市群已成为我国城镇化发展的主体形态,城市群的空间整合是我国城镇化过程中必须解决的重大战略性问题。目前,中原城市群发展形势良好,被认为是我国将形成的十大城市群之一。本文运用分形、城镇化不平衡指数、城市网络、城市空间相互作用等理论和方法,对中原城市群城镇的空间组合状况进行分析;构建促进中原城市群9城市协调组合发展的空间整合机制;依据中原城市群自身发展特色,对其空间整合模式进行选择,并由此提出其空间整合的总体概念模型。

Study on spatial combination characteristics and conformity patterns of the Central Plain city cluster

Now,city cluster has become the principal part of urbanization form of China.The spatial conformity of city cluster is a great strategic matter which must be solved in the urbanization process.At present,the Central Plain city cluster has been developing well,and it has been deemed to be one of the ten great city clusters that China would form.Using geographical theories such as fractal theory about urban special distribution,urbanization imbalance indicator,urban network theory and analysis of urban reciprocity in space and so on,this paper analyzed the spatial combination characters of cities and towns of the Central Plain city cluster.The results show that:(1) the distribution of cities and towns is comparatively dense;(2) the urban spatial distribution takes on a convergence type;(3) the traffic-oriented and sphere layers characteristics of spatial distribution of cities and towns are obvious;(4) the primary urban network structure which has four arteries as the trunks has formed;and(5) the analysis from the angle of urban reciprocity in space,shows that it belongs to the typical "weaker pole and multiple cores pattern".Then,this paper analyzed the ordinary principle about spatial conformity of city cluster,and according to this law,it conceived the spatial conformity mechanism to make the nine cities of the Central Plain city cluster develop harmoniously as a whole.According to the development feature of the Central Plain city cluster itself,this paper considered that in this period,the Central Plain city cluster as a whole should take "sphere layer" pattern of urban spatial conformity;in the local parts,according to the status,it could adopt "axial belt" and "growth triangle" patterns;and in the future when the Central Plain city cluster has been developing maturely,using "double city" pattern would be reasonable.Colligating the above analysis,this paper considered that around 2020,the Central Plain city cluster should strive for spatial conformity as "double core,double circle layers,four axial belts,one growth triangle " as a whole,so that the Central Plain city cluster form the pattern of center centralizing,axial stretching and network contacting.
