基于3S系统的我国城市规模协调性分析

提出了城市规模3S系统的概念,并对城市规模各子系统的单系统协调度及3S系统整体协调度进行了界定;在计算各系统协调度的基础上,对我国城市规模的协调性,从时间和空间两个维度进行了比较。无论是从时间,还是空间的维度,我国城市规模3S系统整体协调性、及各子系统的协调性都比较差,且有进一步恶化的趋势;城市规模3子系统中,城市用地规模子系统的协调性相对较好;东、中、西三区域城市规模子系统协调性的相对优势出现分化。

On the Analysis of the Coordination of City Scale Based on 3S System in China

Firstly,the concept of city scale 3S system is proposed.And then,the coordination degree of single system for each subsystem and 3S system of city scale are defined.From the dimension of time and space,the coordinations of city scale of our country are compared,which based the coordination degree of each subsystem and 3S system of city scale.The results show that either from time or space dimension the coordination of each subsystem and 3S system of city scale are relatively poor and deteriorating.The coordination for subsystem of city built-up area is the best.The comparative advantage of coordination for each subsystem of city scale in sub-regional is differentiation.
