基于中心地理论的中国城市群空间自组织演化解析

The Analysis of Metropolitan Areas Spatial Self-Organization Evolution in China Based on the Theory of Central Place

以克里斯塔勒中心地模型为空间范式,在经济原则、交通原则和行政原则下划分武汉城市圈、长三角、珠三角和京津冀城市群空间单元,与理论模型空间划分进行比较。将现实功能单元划分与理论空间模型之间破碎地块面积与区域总面积的比值作为评价空间自组织演化的指标,用以对比各自的模型拟合度以客观解析中国城市群空间自组织演化状态。结果表明:区域经济总量是影响区域空间自组织演化程度的首要因素,武汉城市圈空间自组织演化尚处于发育阶段,仅相当于长三角城市群的一个空间子系统或二级功能单元,但政府规划建设尤其是交通设施建设较为有序和科学,待其经济总量持续增长,其空间自组织演化将更趋合理。京津冀都市圈空间组织演化合理程度更高,珠三角和长三角城市群空间自组织演化最为合理,处于空间自组织演化高级阶段。同时,相对于巨大的经济总量的差异,处于不同发展阶段的各城市群(都市圈)空间自组织演化水平实际差异并不那么显著,表明空间自组织演化作为空间成长的内生动力规律性明显。

In the principle of economy ,transportation and administration the paper focus on the spatial structure data of the Metropolitan Areas with the theoretical model based on the central place theory proposed by W. Christaller.The study analysis its Evolutionary status of spatial self-organization. The result indicates that economic aggregate is the the most important factor of the patial selforganization. And Wuhan Metropolitan Area is in still in the primary phase of development ,which is equivalent to a subsystem or a subordinate functional unit. With scientific city planning and development especially the trasportation construction the patial self-organization will be more and more reasonable.
