Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Urban landscape patterns influence population health and are traditionally measured using landscape indices. However, current indices suffer from a single-dimensional focus, multicollinearity, and limited health relevance. WHAT IS ADDED BY THIS REPORT? Using a two-stage Generalized Weighted Quantile Sum (GWQS) regression, we developed a Landscape Pattern Health Index (LPHI), integrating composition/configuration metrics. This index revealed seasonal protective/hazard effects and represents a holistic tool for assessing urban landscape health impacts. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? The LPHI identifies high-risk areas and seasonal priorities, thereby guiding targeted interventions to mitigate health risks through landscape optimization.
