摘要
Abstract
Taking Huaihai North Road in Huai'an city, a small-medium city, as the typical road section, this study designed and implemented the street canyon experiment. According to the measured PM2.5 concentration, wind speed and direction, traffic volume, vehicles, speed and meteorological conditions, the canyon model was used to calculate the contribution of motor vehicles with different power sources to PM2.5. It is obtained that the emission factors of various types of vehicles in rainy days are less than those in sunny days, and the emission factors of diesel, gasoline and natural gas decline in succession. The results of qualitative analysis show that it is feasible to use the canyon model to study the PM2.5 emission factors on small and medium-sized city roads and that diesel oil becomes the greatest contributor to PM2.5, and it is suggested to adopt natural gas as the power source in urban traffic.关键词
