【摘要】 为优化城市群交通网络结构,促进京津冀城市群交通一体化与经济一体化的发展,从交通建设度、交通运输度、交通通行度及关联度等方面构建交通网络总体建设水平的评价指标体系,并运用SPSS模型对城市群内的交通节点进行分级,然后运用交通联系度模型对各城市间的交通网络联系进行了定量分析,从而构建了京津冀城市群交通网络联系的基本结构。研究表明,京津冀城市群各节点城市交通网络综合实力的两极分化现象严重;交通网络的联系不健全,存在南北不对称的松散结构;交通网络呈现以北京市为中心的放射式格局并形成以京津为核心的三条主要联系通道。更多还原

【Abstract】 Aimed at optimizing network structure of Beijing-Tianjin-Hebei city cluster,and promoting the development of city cluster traffic integration and economic integration,this paper takes Beijing-Tianjin-Hebei city cluster as study target,the index system of comprehensive evaluation of transportation network is constructed by the traffic-construction,traffic-transport,trafficcrossing and traffic-correlation.what′s more,it uses SPSS model to rate traffic nodes within the city cluster,then applies traffic connection degree model to analyze the transportation network links between cities,so as to build the basic structure of BeijingTianjin-Hebei city cluster′s traffic networks.Studies show that the polarization of urban transport network of comprehensive strength is very serious;traffic network connection is not sound and presents loose structure of the north-south asymmetry;traffic network appears to Beijing and Tianjin as the core radiation out of the three main contact channels,and Beijing as the center of the radial pattern.更多还原
