Purposes of this study are to explore associations between neighborhood landscape elements and public health in a subtropical high-density urban context, elucidate mediating effects physical environmental factors, propose corresponding renewal strategies. Nine sampling sites were selected Guangzhou, China, data collected from 438 participating residents using the MOS item short survey (SF-36 scale). Landscape neighborhoods, including greenness, blue spaces, walking trail systems, squares, garden architecture, dedicated sports spaces mapped by unmanned aerial vehicle surveys. Seven factors measured: heat stress index (HSI), relative humidity (RH), average wind speed (AWS), negative oxygen ions (NOI), <2.5 μM particulate matter (PM2.5), illumination (I), noise (N). General linear models used differences neighborhoods elements. Relationships both as well pathways involved, explored correlation analysis Mediation analyses. In neighborhood, I, RH, HSI, NOI, PM2.5 significantly correlated with squares. Multiple mediation showed that squares affected health, HSI NOI. have close mainly mediated on light, thermal, atmospheric environments. These closely related environments need careful attention efforts.
