京津冀区域空间格局及其优化整合分析

本文以京津冀区域空间结构为研究对象,从点、线、网络和域面四个基本空间要素入手,研究提升区域竞争力的空间整合规律.研究认为,京津冀区域人口和城镇体系的空间分布不均衡,一方面,以自然条件为基础,呈现东南集中特征,另一方面,中小城镇分布以京广、京九、京哈铁路等为依托,呈现以北京为中心的强向心分布；城镇带分布大体可划分为京广线...

Study on the Characteristics of Beijing-Tianjin-Hebei Spatial Structure and the Spatial Integration

Based on the literature review and theoretical analysis,this paper studies the spatial structure of Beijing-Tianjin-Hebei.Studies suggest that comparing with the Yangtze River Delta city group,the Pearl River Delta city group,and the Central China city group,the relative density of cities in Beijing-Tianjin-Hebei is lower.The spatial distribution of urban system is not balanced,on the one hand,based on the natural conditions,more cities locate in the Southeast,on the other hand,most medium-small towns locate on the main railways.The distribution area of cities can be roughly divided into six lines,which are Beijing-Guangzhou line,Shuozhou-Huanghuagang and Shijiazhuang-Dezhou Line,Beijing-Jiulong line,Beijing-Tianjin,Beijing-Harbin,Beijing-Shanhaiguan line and Zhangjiakou-Chengde.There is a decentralization trend in economic development.The transportation infrastructure within the region is relatively developed,with the changes of the economic spatial distribution,the urban traffic demand within the region changes with it.Finally,considering the transportation system of this region,and urban development orientation,the trend of spatial integration can be summarized as "three-axis,four-zone,multi-center network".
