中文摘要：

基于广州市第五次和第六次人口普查数据,以街镇为地理单元对2000-2010年广州市人口老龄化空间变动及其影响因素进行了分析。研究表明：①广州市人口老龄化程度不断加深,空间差异减小,在空间上以圈层结构向外扩张;②人口老龄化速度以中心城区內缘最为迅速;③从空间分布趋势来看,整体上老年人口和人口老龄化的空间集聚趋势有所＂弱化＂,人口老龄化将继续向中心城区扩散,近郊区北部作为年轻型街镇的集聚区域,其集聚作用将更加明显;④就人口老龄化空间格局的影响因素而言,人口迁移的作用相对于人口的自然增长愈发显著,经济发展水平是这一时期老年人口向中心城区內缘集中的主要因素,文化教育水平对老龄化的区域分异具有一定正向影响。

英文摘要：

Based on the 5th and 6th Population Census, the spatial change and influence factors of population aging in Guangzhou City with street and town as the research unit were analyzed. The results indicate that： ①The population aging has been deepening with a decrease in regional differentiation and outward expansion in a circle direction. ②The population aging is going on most rapidly in the edge of the central urban area. ③The tendency of spatial concentration of aged population and population aging has been weaken. Population aging continuously expands to the central city, and the north suburbs become the aggregation area of new streets and towns with stronger function of population concentration. ④With regard of the influence factors to the spatial change of population aging, population movement plays a more important role compared to the natural growth of population. Economic development serves as the key factor stimulating aged people concentrated in the edge of central city, while educational level keeps positive impact on the regional differentiation of population aging.
