In this special era of rapid aging,socio-economic transformation,and urban-rural spatial reconstruction,the need for interdisciplinary studies of geography,sociology,and gerontology become urgent,and geographic gerontology research is attracting extensive research attention.At present,geographic research on aging mainly concentrates on the spatio-temporal patterns and determinants of population aging,the spatial effects of population aging,the relationship between older people's health and environment,the spatial behaviors of older adults,and the planning for elder healthcare services.Although these studies have provided useful insights for understanding and coping with the challenges of an aging society,some basic concepts still need to be clarified to meet the needs of"age-friendly society"in practice.In particular,it is necessary to distinguish the particular characteristics of older people's demands from other populations.This paper presents research in line with this within a regional system composed of the relationships of people,society,and environments in the context of aging,and tries to broaden the perspectives of geographic gerontology research.
