成都大都市区空间范围划定研究

Study on Spatial Scope Division of Chengdu Metropolitan Area Based on Commuting Transport and Administrative Management

摘要:

国内超大城市已进入大都市区发展阶段，空间组织机理和管治模式均已发生重大变化，但国内至今尚无官方的大都市区统计制度、规范标准等。为研究大都市区地域范围划分方式和划定标准，以东京都市圈、巴黎大区和首尔大都市区为研究对象，采用归纳演绎方法，从行政地域和功能地域两个层面进行了深入比较。结果表明：大都市区空间范围与交通运输水平紧密关联，其范围具有动态调整的特征；按照5%通勤率指标界定成都大都市区范围，其空间尺度约为3 500 km²，近期划定范围与传统总体规划划定的城市规划区、当前国土空间规划划定的城市集中建设区范围接近；基于行政单元划定的大都市区具有较强的操作性，有利于数据横向比较和学术研究，实践中应积极采用基于行政单元的划分方式。

Abstract:

In China， the megacities have entered the stage of metropolitan development， and the spatial organization mechanisms and governance models have been greatly changed. However, there is currently no official statistical system, standardized and norms for the metropolitan areas in China. To study the methods and criteria of regional division of metropolitan areas, taking the Tokyo metropolitan area, the Paris metropolitan area and the Seoul metropolitan area as examples, the inductive-deductive approach is used to deeply compare two levels of administrative region and functional region. The results indicate that the spatial extent of metropolitan area is closely linked to transportation levels. Its extent has the dynamic adjustment characteristics. The metropolitan area of Chengdu is defined according to the index of 5% commuting rate. Its spatial scale is approximately 3 500 km2. The recently delimited scope is close to the urban planning area delimited by the traditional master plan and the urban centralized construction area delimited by the current territorial spatial plan. Based on administrative units, the delimited metropolitan areas have the strong operability, which is conducive to horizontal data comparison and academic research, and the division based on administrative units should be actively adopted in practice.
