| 摘 要： | 城市体系的空间结构具有分形特征,分维是反映空间结构优化与否的重要参量。基于分形理论,通过计算关中-天水经济区城市体系的集聚维数和关联维数,探讨分析了该经济区城市体系空间结构的特征,得出关中-天水经济区存在着核心城市不强、城市空间分布集聚不明显、城市体系等级缺失、城市之间关联较弱等制约经济区健康快速发展的因素。最后指出应进一步优化关中-天水经济区城市空间结构以便为促进经济区发展以及西咸国际大都市建设发挥持续性的积极作用。

| Abstract: | the spatial distribution of urban system is possessed with fractal characteristics, dimension is a significant parameter reflecting whether the spatial structure is optimal or not. The concentration dimension and correlation dimension in Guanzhong-Tianshui economic region were calculated and the system of spatial structure of urban system in the region was discussed based on the fractal theory in the paper. The study results indicated that the factors, i. e. the inconspicuous concentration of urban spatial distribution, poor correlation degree, etc. restricting the healthy development of the economic region. |
