摘要
为加强区域内部资源整合与生产力要素合理配置,进而实现京津冀都市圈各城市间协调发展与经济腾飞,从空间格局角度,结合最新行政区划、基础地理数据库及其统计资料,运用重力模型和栅格网络分析方法,对京津冀都市圈内各城市地理区位优势和出行运输便捷程度进行定量分析。研究结果表明,京津冀都市圈内区位优势等级以天津市、北京市为中心向外逐级递减,天津市因其对各区位影响因子的均衡接近性而表现出最高的区位水平,北京市次之,而承德、张家口各县市处于劣势区位。都市圈内各城市公路交通基础设施建设发展水平相对均衡。
Aimed at evaluating both of location advantage and transportation accessibility of Beijing--Tianjin--Hebei（Jing--Jin -Ji） metropolitan area, this paper from the perspective of spatial configuration adopted both the latest administrative division atlas and the fundamental geographic information database and statistics, with GIS spatial analysis methods as well, to conduct quantitative analysis and explicit descriptions on every present cities within the metropolitan area. The results showed that Tian- jin,Beijing and Langfang possessed the obvious regional advantages, in which Tianjin occupied the highest level. Meanwhile Cbengde and Zbangjiakou were comparatively backwards,mainly caused by the mountainous and hilly surroundings. Besides, it also showed a relatively balance to the overall performance of urban highway construction. Moreover, Qinhuangdao, Cangzbou and Sbijiazbuang built close contact with nearby regions out of Jing-Jin-Ji metropolitan area, by their intensive transportation networks and their peripheral locations.
