The Role of “Nostalgia” in Environmental Restorative Effects from the Perspective of Healthy Aging: Taking Changchun Parks as an Example

Aging and elderly health issues have always been the focus of attention, both within and outside the industry. With the introduction of the national “14th Five-Year Plan” for healthy aging, it is urgent to address how to implement this plan. Among them, the restorative environment is an important part of implementing healthy aging. For older adults, “nostalgia” is a common emotional experience, and “nostalgia therapy” is also commonly used for mental health recovery, which has important significance for healthy aging. However, although existing research on “nostalgia” has already involved local attachment and the environment, there are few studies that use space as a carrier in the context of environmental restorative effects. Therefore, from the perspective of healthy aging, combined with structural equation modeling, this study took four parks in Changchun City as examples to explore the role of “nostalgia” in the restorative effect of the park environment. It found that, firstly, both the “nostalgia inclination” influenced by individual conditions and the “landscape perception” influenced by landscape quality had a positive impact on the “nostalgia affection”; secondly, nostalgia affection and place attachment were important mediating factors for environmental restorative effects, and the pathways of “landscape perception → nostalgic affection → environmental restorative effects”, “landscape perception → place attachment → environmental restorative effects”, and “landscape perception → nostalgic affection → place attachment → environmental restorative effects” all existed. Based on the above path exploration, corresponding spatial optimization ideas for effectively improving the health level of older adults have been provided.
