| 摘 要： | 运用分形理论研究福建省城市体系规模分布的自相似性质和特征,借助分维及城市规模分布的均衡度指数分析福建省城市体系等级结构演化的动态特征,运用R/S分析方法对城市体系演化趋势作出预测,结果显示福建省城市规模分布的分维值有持续上升的趋势.论述了分维值上升的利弊,并根据分形优化原理提出改善福建省城市等级结构的措施.

| Abstract: | Studies the fractal features of the city-size distribution of urban system in Fujian Province.The fractal dimension and the equilibrium degree have been used to analyse the evolving characteristics of the hierarchical system in Fujian Province.The trend has been predicted by means of rescaled range analysis(R/S analysis),which shows that the value of fractal dimension exponent has been gradual increasing.The advantages and disadvantage of rise of fractal dimension are analysed and weighed.Finally,it is pointed out how to improve the hierarchical system of towns in the studied region by means of fractal theory. |
