摘要
目的分析宝鸡市人口老龄化的空间特征及其影响因素,为应对老龄化问题提供依据。方法利用第五次人口普查数据,采用数据对比、空间聚类分析、灰色关联分析等方法,分别对宝鸡市人口老龄化的基本特征、地域差异、空间分布及其影响因素进行分析。结果截至2000年,宝鸡市的老龄化特征已十分显著;人口年龄结构地区差异明显;市中心区老龄家庭比重较大;年龄中位数、老龄人口密度、迁入人口数等与老年人口比重关联度较大。结论宝鸡市中心区人口老龄化特征显著,且有进一步强化的趋势,建议采取相应措施。
Aim The spatial characters of population ageing and its influencing factors were analyzed to provide scientific basis for countermeasures. Methods Based on the Fifth National Popula- tion Census, the basic features, regional difference, spatial distribution and the influencing factors of the population ageing in Baoji City are analyzed respectively with the methods of data comparison, spatial cluster analysis and grey correlation analysis. Results Up to 2000, the characteristics of the population ageing in Baoji City are quite significant; the age compositions of population vary remark- ably in different regions; the proportion of ageing families in central region of Baoji City is relative high; the median age, the ageing population density, the immigrating population, etc, have great re- lation to the proportion of ageing population. Conclusion The population ageing of the central region of Baoji City is significant, with the trend of aggravating, while some countermeasures are proposed to deal with these.
