摘要
文章基于第六次和第七次人口普查数据,以乡镇街道为空间单元,运用回转半径、标准差椭圆、空间自分析,以及冷热点分析等多种方法对延边州人口老龄化空间演变特征进行分析,并对其影响因素进行探讨。结果表明:(1)2010—2020年,延边州由以吉林省延边朝鲜族自治州延吉市中心城区为核心的单圈层结构,转变为以敦化市、延吉市和珲春市中心城区为核心的“三足鼎立”的新圈层结构模式,且人口老龄化进程随时间不断加速,整体上由轻度老化时代发展为深、极度老化时代。(2)延边州人口老龄化标准差椭圆总体上呈现“东(偏南)—西(偏北)”的分布格局,与2010年相比,2020年这种分布格局趋势有所弱化。(3)延边州各乡镇街道人口老龄化存在显著的空间正自相关性,且随着时间的推移,人口老龄化发展在空间上表现出向敦化、延吉、珲春三市中心城区集聚的倾向,并逐步呈现出“老年人口规模大—老龄化程度低”的趋势。(4)经济因素、社会因素、人口发展因素,以及交通因素,是影响延边州人口老龄化空间分布的主要因素。
Based on the data of the sixth and seventh census, taking township streets as the spatial unit, this paper analyzes the spatial evolution characteristics of population aging in Yanbian Prefecture by using various methods such as radius of gyration, standard deviation ellipse, spatial autocorrelation analysis and cold and hot spot analysis, and it discusses its influencing factors. The results show that:(1) From 2010 to 2020, Yanbian Prefecture has changed from a single circle structure with the central urban area of Yanji as the core to a new circle structure model with Dunhua, Yanji and Hunchun as the core, and the process of population aging has accelerated over time. On the whole, it has developed from a mild aging era to a deep and extreme aging era.(2) The standard deviation ellipse of population aging in Yanbian Prefecture generally presents a distribution pattern of ’East(South)-West(North)’.Compared with 2010, this distribution pattern trend will be weakened in 2020.(3) There is a significant spatial positive autocorrelation in the population aging of villages, towns and streets in Yanbian Prefecture. With the passage of time, the development of population aging shows a spatial tendency to gather in the three central urban areas of Dunhua, Yanji and Hunchun, and gradually presents a situation of ’huge scale of elderly population-low degree of aging’.(4) Economic factors, social factors, population development factors and traffic factors are the main factors affecting the spatial distribution of population aging in Yanbian Prefecture.
