Exploration on the Influence of Spatial Perception on Urban Residents' Well-being Under High-density Urbanism

Abstract

Based on the background of urban stock renewal in China, this study aims to clarify the correlation mechanism between high-density urban spatial perception and residents' physical and mental health. The study integrates public data such as the Urban Construction Statistical Yearbook of the Ministry of Housing and Urban Rural Development, the research results of the China Academy of Urban Planning and Urban Rural Development on the built environment, the ledger of national urban built-environment surveys, the national mental health census, and chronic disease monitoring. Field research data from three high-density cities, Shanghai, Shenzhen, and Hong Kong, are selected as analysis samples to classify spatial perception into five dimensions: crowding, openness, privacy, accessibility to supporting facilities, and greening. Starting from physical characteristics including building layout, green space construction and street-block scale, this study analyzes how objective built environment affects residents via subjective perception, forming such influencing paths for sleep quality, chronic disease incidence and social interaction. Drawing on these findings, combined with the acceptance data of the renovation of old residential communities and pocket parks in China, this paper accordingly puts forward targeted spatial optimization strategies; existing planning schemes tend to focus on hard indicators such as plot ratio, and generally ignore the health intermediary value of spatial perception. The relevant conclusions can provide a practical basis for the formulation of district control plans and the refinement of community updates, so as to balance intensive land use and residential livability.
