| 摘 要： | 运用分形理论,以上海为研究区域,结合统计分析、GIS分析技术,测算上海人口分形分维数,依据分形理论对上海区域进行人口分布和郊区化的分维刻画,探讨上海人口郊区化空间推进的规律,可以得出以下结论:人口分布分形维数的测算表明,上海人口郊区化以来,全市及中心城区的人口分布的集聚程度有所缓和,人口分形性态呈现优化,但是上海人口郊区化目前还只是近郊郊区化,还没有发展到远郊郊区化. |
| 关 键 词： | 上海 郊区化 分形 |

| Abstract: | Adopting analyses of relevant statistics and GIS and based on the fractional theory,this paper attempts to explore a general role of population suburbanizing in Shanghai by using Shanghai's censuses from 1982 to 2003.The fractal dimensions(box fractal dimension and correlation fractal dimension)of population distribution in Shanghai are calculated and the relationship between fractal characteristics and changes of population distribution is discussed here.The research concludes that from the 1980s to 2003 the fractal characteristics are good guidelines for reflecting suburbanizing of Shanghai,showing lower population growth in its down-town area,compared with higher population growth in its suburbs. |
