Abstract

In order to the research on the diffusion of the particles in street canyons under elevated roads, field measurements of the diffusion of respirable particles were carried out, which conducted at different heights, atmosphere temperatures and the vegetation coverage. At the same time, the correlation analysis was introduced. The results show: particulate mass concentration in street canyons is negatively correlated with height, respirable particulate matter concentration first decreases with increasing height and increases suddenly over the elevated road; particulate mass concentrations in the street canyon is negatively correlated with blast temperature, with the increase of atmospheric temperature, particulate mass concentration in street canyons is gradually reduced. The greater the degree of vegetation coverage near the building, the more significant the blocking effect of the building below the three story building.
