To investigate the impact of urban community built environments on residents' quality of life, and offer empirical support for health-oriented urban planning.

This study employed a multi-stage random cluster sampling method to survey the permanent residents in 1 401 households across 26 communities and 49 residential areas. Based on the research objectives, 2 086 adult participants were included for analysis. The study integrated multi-source geospatial data and utilized linear mixed-effects model to investigate the association between the built environment and residents' quality of life.

The mental component summary (MCS) score of residents was 49.16±11.58, and the physical component summary (PCS) score was 49.99±10.12. Linear mixed-effects model results showed that green view index (β=2.428, P<0.05), motor vehicle ratio (β=3.180, P<0.05), public transport stop density (β=2.113, P<0.05), road intersection density (β=2.854, P<0.05) and park green space ratio (β=3.048, P<0.01) were positively correlated with MCS; road network density (β=-2.963, P<0.01) and floor area ratio (β=-3.075, P<0.05) were negatively correlated with MCS. For PCS, green view index (β=1.154, P<0.05), motor vehicle ratio (β=2.197, P<0.01) and building density (β=2.018, P<0.05) were positively correlated, while floor area ratio (β=-1.761, P<0.05) was negatively correlated. Additionally, road network density interacted with building density (β=0.979, P<0.05) and green view index (β=-1.112, P<0.05) in affecting PCS.

The built environment of urban communities is closely linked to residents' quality of life. In urban spatial governance, emphasis should be placed on the systematic optimization and synergistic enhancement of various built environment elements to promote community residents' well-being.
