  • 采用综合指标评价法、引力分析法以及断裂点分析法对2015年京津冀城市群13个地级以上城市的空间关联和影响强度进行了测度研究.研究表明:①各城市之间的综合发展质量和职能强度差异明显,“中心—外围”的两极分化发展特征显著;②各城市对外联系强度的地域分异特征明显,其联系强度以“北京—天津—廊坊”一线为出发点,向南北方向逐渐递减,核心城市存在单极化发展、职能弱化和辐射带动作用不强的问题;③北京、天津等核心城市对周边区域的辐射影响范围较大,并对石家庄等次核心城市产生了一定的屏蔽作用. The paper adopted the comprehensive index evaluation method,the gravity model and the fracture point model,and analyzed the spatial correlation and impact strength of the 13 cities of Beijing-Tianjin-Hebei Urban Agglomeration.The results shows that:(1) The cities are significantly different in their comprehensive development quality,which shows a significant polarization characteristic;(2) The geographical differentiation of cities' external contact intensity is obvious,and from the urban belts of "Beijing-Tianjin-Langfang",the urban spatial connection diminishing gradually to north and south,and the prevailing problems of the core cities are namely single polarization development,weakening urban function and weak driven effect of radiation;(3) Beijing,Tianjin and other central cities have a bigger radiation impact area to other cities,and in the meantime have a shielding effect on Shijiazhuang.
