【摘要】 文章通过计算甘肃省城镇体系的首位指数、不平衡指数及城市规模分形分布的分维数,讨论了甘肃省城市体系的等级规模结构的特点;用城镇密度、关联维数分析了甘肃省城镇体系的空间结构,指出了目前城镇体系的特征:首位度过大;城市体系规模结构出现断层,联系不畅;空间布局小集中、大分散;城市空间相互作用力较弱,大城市没有发挥应有的辐射作用;城镇体系结构受到自然条件的影响显著。进一步探讨了这种城镇体系结构特征形成的内在机制,最后作者在此基础上提出了未来甘肃城镇体系发展的相应对策:大分散,小集中,重点发展中小城市,完善城镇体系规模结构;坚持分散化的道路,完善城镇空间结构;大力促进农村小城镇的发育。更多还原

【Abstract】 At first, the paper discusses the scale structure of the urban system of Gansu province by figuring out the primate city index, the scale imbalance index and the fractal dimension of the town-size distribution of Gansu province. Then analyses, the spatial structure of the urban system by using the city-town density and the spatial correlation dimension. According to these analyses, it points out there are some deficiencies in the urban system of Gansu province, such as: the law of the primate city is too big, there is a faultage in the urban system, spatial structure is illogical, the capacity of spatial interaction is weak. Through analyzing the present feature of the scale structure and the spatial structure, the paper puts forward the direction for developing the urban system of Gansu province: take middle-small cities on stress, perfect the urban system of Gansu province.更多还原
