Objective To investigate the agglomeration of particulate matter at the air-leaf interface and provide guidance for the prevention and control of particulate matter and greening planning. Methods In this study, the effects of temperature and wind speed on plant coagulation effect were studied by using a self-developed system of coagulation effect based on aerosol smoke box, and the coagulation effect of particulate matter in the leaves of 10 common green tree species in Shanghai was measured. Results The coagulation effect of plant leaves is affected by external conditions, which increases and then decreases with the increase of temperature and is positively correlated with wind speed; among different plants, the coagulation effect of coniferous species is greater than that of broad-leaved species, small-leaved species is greater than that of large-leaved species. Conclusion The results of the study can provide scientific basis for the key prevention and control management of haze, the plant configuration mode of green space community and the selection of urban greening tree species.
