  位序-规模法则zipf定律空间结构双分形多分形对称性美国城市
• An empirical analysis is made with the population data of the us cities to verify the theory and models developed in this paper , which will contribute to reconcile the apparent difference between the hierarchical step - like frequency distribution of city sizes suggested by central place theory and the smooth curve reflected by the work on the rank - size rule
  多重zipf维数模型不仅可以有效地统一中心地的等级阶梯与位序-规模法则反映的连续分布，而且可以揭示城市体系演化的更多信息和隐含法则。以美国城市体系1998年的数据为实证对象，给出了城市规模分布的多分维
• In order to grasp the urban system processes and evolution pattern of hunan province comprehensively , this article has made further discussion on its structure characteristic : through regression analysis , graph analysis and statistics analysis of the time series data and cross sections data , by combining with the fractal theory , we induce the following conclusion : the hierarchical size structure presents the law of the primate city , the rank - size rule and pyramid structure characteristic , but it also has the insufficient development problem of the high hierarchical size city . by using the gravitation model , we found out that the economy relation intensity among those main cities is weak while the structure is loose . based on the urban layer system of economic development level and industrial structure evolution of the cities in hunan province , this article then induces the function combination among the five urban agglomerations in hunan province
  为全面把握湖南城市体系的运演规律,本文对其结构特征作了进一步的探讨:通过时序数据和截面数据的回归分析、图表分析和统计分析,结合分形理论,得出了其等级规模结构分布呈现出首位分布、位序?规模分布和金字塔结构特征,以及存在着高层次城市发展不足的问题;运用场引力模型发现该省主要城市间的经济联系强度较弱、结构松散,在归纳出该省城市经济发展水平的层次体系、产业结构演变的基础上,导出了该省城市体系的五大城市群职能组合;结合空间结构体系、路网交通条件和经济发展状况,对该省城市空间分布状态进行了定性分析,研究表明该省总体上处于极化阶段,各个具体区域,分布阶段不一,差异较大。
