基于多维视角的河南省城市-区域系统空间结构特征分析

城市-区域系统的空间结构与区域的协同、综合发展相互依赖、密不可分,整合与优化空间结构可有效地促进区域系统中城市的协调、持续发展.基于扩展断裂点、分形、城市空间分布、空间相互作用等空间结构分析方法,对河南省城市-区域系统空间结构特征进行分析与评价.研究表明河南省城市-区域系统空间结构具有以下特征:城市空间影响范围具有不均衡性;城市之间的空间关联性不够强;城镇点在空间上随机、均匀分布;城市相互作用强度梯度差异大.

Analysis of Spatial Structure of City-Region System in Henan Province

The spatial structure of city-region system is interactively affected with the coordination and comprehensive development,it is important to effectively promote the city in the city-region system to coordinate and sustainable development by integrating and optimizing spatial structure of city-region system.In Henan Province,it is an effective method to solve the problems of urban-rural and region,to enhance the comprehensive competition force of central urban agglomeration,Henan Province and central economic district and to promote the regional economic growth.This paper gives an analysis of spatial structure of city-region system by the methods of weighted voronio map,the distribution of city,spatial analysis and spatial interaction.The result shows that the urban influenced scope is unbalanced,the urban spatial relevance is not strong,the city spot of spatial distribution is random and even and the urban spatial interactive strength is in a large level variation.
