摘要
1990年代以来,安徽省城市发展速度明显加快。为了定量分析安徽省城镇人口规模结构的变化规律,运用分形方法,以1996年、2001年和2006年的安徽省城镇人口统计数据为样本,分别计算了城镇人口规模结构的分形维数。计算结果表明,近十年来安徽省城镇人口规模结构发生积极的变化,城镇人口规模结构已由低水平均衡分布向首位型分布转变,中间位序的城镇数量还比较多,并据此提出了城镇化发展的对策建议。
Fractal study is one of the most important content in modern theoretic geography,and the urban system fractal study is a new way for the study of the city geography especially,fractal dimension is an effective parameter describing the structure of the urban system.This paper commences with the application of the urban system fractal theory and tries to find the rule of the urban population scale structure in Anhui Province.Based on the fractal theory,the paper analyzes the scale structure of urban system in Anhui Province,and finds out that the urban system has the fractal properties,so the paper thinks that fractal theory can fit to calculate and analyze the scale structure of urban system in Anhui Province.According to the results of calculation and analysis,the paper draws the conclusions that great changes have taking place in scale structure of urban system in Anhui Province.The distribution of the scale structure of urban population scale structure has changed to the first type from low-level equilibrium,and rank among the number of cities and towns still are more.According to the conclusions mentioned above,the paper put forward policy proposals for the development of urbanization.
