Research on the resilience regeneration and planning of the aging community in the post COVID-19 era

Since 2020, COVID-19 has swept around the world, cities has suffered unprecedented challenges: economic halt, limited interpersonal interaction and compressing space. The epidemic has suppressed the vitality of urban space around the world, while urban space has gradually lost its economic function, its social interaction function has also been weakened. In particular, the elderly population over 60 years old with high risk of disease is in a period of strong social demand, affected by the epidemic, they have to reduce economic and social activities, and endure the pain of decreased income and social communities. With the epidemic situation gradually turning into the control period in the world, we need to summarize and reflect on the vulnerability characteristics and health and safety problems of the cities exposed under the impact of the epidemic, and strengthen the resilience of the city and ensure the urban health and safety are the focus of urban planning and governance in the future. This study aims to explore the practical approaches of resilience regeneration and planning of "old community" with a relatively concentrated elderly population from the urban community level, improving the ability of aging communities to resist public health emergencies, promoting the economic and social activities of the elderly in the community, and increasing the physical and mental health index and happiness index of the elderly. Our study first review the relevant researches on the concepts and theories of resilient city, healthy city and active aging to understand their origin, development and evolution; Secondly, it constructs the theoretical framework of resilience regeneration planning based on the aging community to provide theoretical support for the resilience regeneration and planning practice of the community; Thirdly, the advanced cases of international resilient community construction are analyzed and used for reference to understand its development process and practical methods; Finally, taking some aging communities in China's first-tier cities (Beijing, Shanghai, Shenzhen, Guangzhou) as the objects, through the exploration and practice of community resilience regeneration, we can promote the economic and social interaction activities of the elderly population in the community, enhance the ability of the community to deal with the practice of public security, and provide some exploratory ideas for the theory and practice of community resilience planning in the post COVID-19 era.
