Abstract
This study examines the spatial distribution of PM₂.₅ in a typical street canyon in Harbin and evaluates its relationship with the green interface index. By connecting measured particulate-matter patterns with the visible composition of street greenery, the research explores how the spatial characteristics of green interfaces can inform the assessment and design of urban street environments.
Keywords: PM₂.₅ distribution; green interface index; street canyon; urban greenery; Harbin.
