摘要
定量研究了城市道路机动车各车型对道路二次扬尘中总悬浮颗粒物(TSP)与可吸入颗粒物(PM10)的贡献率.在上海市杨浦区军工路部分路段采集TSP浓度、PM10浓度、气压、温度、风速及不同车型流量等数据,利用高斯扩散模型反推污染物源强,并据此计算出污染物单车排放因子.运用多元回归分析得知,小型车的两种污染物贡献率为负,中型车与大型车的贡献率为正,且大型车两污染物的贡献率分别为中型车的1.74倍和1.56倍.
Different types of motor vehicles＇ contribution rates of TSP and PM10 in second fugitive dust on urban road were analysed quantitatively.Concentration of TSP,concentration of PM10,pressure,temperature,wind speed,traffic volume of different types of motor vehicles and other informations were collected in some sections of Jungong Road in Shanghai city.Gaussian atmospheric diffusion model was used to identify reversely the source intensities of pollutions as well as the average motor vehicle emission factor.With multivariate regression method,it can be seen small-type motor vehicle＇s both pollutions contribution rates are negative,while middle-type motor vehicle＇s and large-type motor vehicle＇s are positive,and the latter one is ones are respectively 1.74 times and 1.56 times as great as the former one.
