ABSTRACT

Particulate matter (PM10) that threatens human health has now become a social disaster. The urban form and physical characteristics are important factors that determine the dispersion of air pollutants. The aim of this paper is to explain the relationship building coverage ratios and the concentration of PM10 in urban street canyons where the concentration of PM10 is high. For this study, ENVI-met software was used after setting alternatives according to the change in the building coverage ratios and aspect ratio. Multiple regression analysis was performed with the concentration of PM10 as a dependent variable, building coverage ratios as an independent variable, and wind direction, wind speed, and air temperature as control variables. As a result, it was found that the concentration of PM10 increased as the building coverage ratios of the street canyons increased. This study suggests the change of the concentration of PM10 according to the building coverage ratios in street canyons and suggests that building coverage ratios should be considered in urban design.
