【摘要】：中国已全面进入快速老龄化社会,研究老龄人口空间集疏格局及形成机制,不仅是开展老龄人口空间研究的理论基础,也是指导面向老龄化社会城市更新问题的关键所在。选取地级以上行政单元为研究对象,基于五普、六普老年人口数据,采用老龄化率、集聚度和空间自相关等方法,定量分析2000年和2010年全国城市老年人口分布的集疏格局及空间关联。研究表明:全国地级以上城市总体处于老龄化中期水平,城市间老龄化空间分异较大,老年人口密集区城市主要分布在胡焕庸线以东,稀疏区城市则均位于胡焕庸线以西,这与总人口分布状况基本一致;高密区城市基本都分布在东部沿海地区,中密区主要分布在长三角、珠三角、中原、山东半岛、成渝和京津冀地区,为中国分布范围最广的老年人口集聚区;城市间人口老龄化存在较强的空间正相关特征,空间集聚状况有所增强,人口老龄化空间格局表现出以热点区为中心,逐渐向外围过渡的"中心—外围"结构;自然环境、经济环境、城市化建设、人口环境等是导致老年人口集疏格局的关键形成因素。
[Abstract]:China has entered an aging society in an all-round way. To study the spatial pattern and formation mechanism of the aging population is not only the theoretical basis for the spatial research of the aging population, but also the key to guide the urban renewal of the aging society. The administrative units at or above the prefectural level are selected as the research objects. Based on the data of the five and six popular elderly population, the methods of aging rate, concentration and spatial autocorrelation are adopted. Quantitative analysis of urban elderly population distribution pattern and spatial correlation in 2000 and 2010. The results show that the cities above the prefectural level are generally in the middle stage of aging, and the spatial diversity of aging among cities is large. The cities in the aged densely populated areas are mainly located to the east of the Hu Huanyong line, while the cities in the sparse areas are all located to the west of the Hu Huanyong line. This is basically consistent with the distribution of the total population. The cities in the high density areas are basically distributed in the eastern coastal areas, while the middle density areas are mainly distributed in the Yangtze River Delta, the Pearl River Delta, the Central Plains, the Shandong Peninsula, the Chengdu-Chongqing and the Beijing-Tianjin-Hebei regions. It is the most widely distributed elderly population agglomeration area in China. There is a strong spatial positive correlation between the urban population aging, the spatial agglomeration situation is enhanced, and the spatial pattern of population aging shows that the hot spot is the center. The "center-periphery" structure, natural environment, economic environment, urbanization construction, population environment and so on are the key factors leading to the pattern of the elderly population.
