人口年龄空间分布的分形模式

Fractal Patterns in Spatial Distribution of Population by Age Group

Mariko I. Ito, Takaaki Ohnishi

摘要:

多重分形是种群空间分布的一种模式。在这项研究中,我们进行了多重分形分析的人口年龄组在日本首都地区。各种群总体上表现出人口密集地区相互之间相对联系的特点。我们还调查了年龄组的多重分形的依赖。多重分形测度表明,由年轻劳动年龄人口组成的群体表现出很强的异质性和人口集中性,而由老年人组成的人口则表现出相对同质的性质。

英文摘要:

Multifractality is one of the patterns observed in spatial distributions of populations. In this study, we performed multifractal analysis for populations by age group in the capital area of Japan. Each population group generally exhibited the property of densely populated locations being relatively connected to each other. We also investigated the dependence of multifractality on the age group. Multifractal measures showed that the group consisting of young working-age people exhibits strong heterogeneity and concentration of population, while the population consisting of elder people exhibits a relatively homogeneous nature.
