摘要
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 fimction 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.
