| 摘 要： | 基于分形理论以街道（乡镇）为单元，对上海市及其典型区县1994-2002年的人口资料进行研究，测算上海市及其典型区县人口分布的盒子维值（D0）和相关维值（D2）以及相应的相关系数，发现上海市及其典型区县人口分布分形性态明显，不同地域层次的人口分布分维值呈现不同的时间演化趋势，利用分形很好地解释了上海市及其典型区县当前人口分布的空间格局．同时本研究也涉及人口分布数据分形处理的误差和及其影响的探讨．

| Abstract: | The box-counting dimensions(D0s),the generalized q-Dimensions(D2s,q=2) and the corresponding correlation coefficient(r2) of urban population distribution are calculated on the basis of the population distribution data from 1994 to 2002 in Shanghai and some of its districts at the levels of township,town and residential district by adopting the fractal theory.Multifractal characteristics and the spatio-temporal dynamic evolution of population distribution in the regions such as Jing'an,Hongkou,Yangpu,Pudong,Minhang and Jinshan are discussed in detail.The population spatial distribution pattern is perfectly interpreted by using population fractal.An analysis is made of the relationship between urbanization and population fractal in Shanghai.Finally,this paper also discusses the errors and effects of the population fractal data processing. |
