摘　　要：目的对甘肃省近30年人口老龄化空间格局演变进行分析,探讨其空间分布模式及地区差异。方法收集甘肃省1990—2020年14个市(州)的老年人口数据,选择老年人口系数、相对人口老龄化程度与老龄化速度指标对甘肃省老龄化发展进行评价,利用空间自相关分析甘肃省市级单元人口老龄化空间格局演变的特征。结果甘肃省的老龄化发展趋势十分严峻,金昌市、白银市的老龄化发展尤为突出,甘肃省的老龄化趋势呈现出由东南到西北逐渐发展的特征,各单元间的老龄化呈现正向的空间聚集效应,高值聚集区与低值聚集区有所迁移,甘肃省南部是高值聚集区的主要分布区域,低值聚集区由甘肃省北部转为少数民族聚集区的西南部,各区域间老龄化发展不平衡问题逐渐凸显。结论甘肃省老龄化水平与空间分布模式逐渐增强,空间聚集性特征明显。Objective To analyze the evolution of the spatial pattern of population aging in Gansu Province over the past 30 years,exploring its spatial distribution patterns and regional differences.Methods Data on the elderly population from 14 cities(prefectures)in Gansu Province from 1990 to 2020 were collected.Indicators such as the elderly population coefficient,relative aging degree,and aging speed were selected to evaluate the aging development in Gansu Province.Spatial autocorrelation analysis was conducted to examine the characteristics of the evolution of the spatial pattern of population aging at the city level in Gansu.Results The trend of aging in Gansu Province was quite severe,with particularly notable aging development in Jinchang and Baiyin cities.The aging trend in Gansu Province exhibited a gradual development from the southeast to the northwest,with a positive spatial clustering effect of aging observed among various units.High-value and low-value clusters shifted,with the southern region of Gansu being the primary area of high-value clustering,while low-value clusters transitioned from the northern region of Gansu to the southwestern area populated by ethnic minorities.The issue of imbalanced aging development among different regions gradually became prominent.Conclusion The level of aging and the spatial distribution pattern in Gansu Province are strengthening gradually,with significant characteristics of spatial aggregation.
