“分散布局”与“分步发展”:雄安新区城镇体系与子城镇团构建

"Decentralized Layout" and "Step-by-Step Development" :Establishment of the Urban System and Suburban Town Groups in the Xiong'an New Area

雄安新区的设立是京津冀协同发展的战略举措,雄安新区在承接京津大都市疏解职能的同时,也将京津保等城市整合在了一起,盘活了京津冀城市体系新格局,这是大都市从吸收发展过渡到分散发展的重要选择。雄安新区在发展过程中需要遵循"分散布局"和"分步发展"原则,同时也要充分尊重村镇的既有发展基础。"分散布局"即在"安新县+雄县+容城县"三角形区域得到充分发展的基础上,要分别以安新县、雄县和容城县为核心构建子城镇团。其中安新子城镇团由"安新县+高阳县+任丘市"整合而成,形成"三角形+主副团+城镇链"城镇体系发展框架;雄县子城镇团由"雄县+霸州市+文安县"整合而成,形成"四边形+3C"城镇体系发展框架;容城县子城镇团由"容城县+高碑店市+定兴县"整合而成,形成"3C+人字形城镇链"发展框架。在发展步骤上需要划分为A区与B区两个环形区域,按照"先内后外"的顺序逐渐形成"广域雄安"城镇体系,成为整合京津冀城市体系的节点。

The establishment of Xiong＇an New Area is the strategic measure of Beijing-Tianjin-Hebei Cooperative Development. It performs the easing function of Beijing-Tianjin metropolitans, integrates Beijing, Tianjin and Baoding, and enlivens the Beijing-Tianjin-Hebei urban system. It is an important choice from the excessive absorption of urban development to decentralization. In the course of development, the new area needs to follow the principle of ＂decentralized layout＂ and ＂step-by-step development＂ on the current urban basis. ＂Decentralized layout＂ relies on the full development of ＂Anxin-Xiong-Rongcheng County Triangle＂, with respective suburban groups, in which the Anxin suburban town group group consists of a triangular city-chain of Anxin, Gaoyang and Renqiu; the Xiong group consists of a quadrangular-C-shaped urban system of Xiong, Bazhou and Wen＇an; the Rongcheng group is composed of a C-V-shaped city frame of Rongcheng, Gaobeidian and Dingxing. As to the procedure of development, the new area should be divided into two different zones in the inside-out process in order to form a gradual ＂Broad Xiong＇an＂ city system as a node of Beijing-Tianjin-Hebei integration.
