摘要:

道路交通污染物排放已日益成为城市空气污染源重要的因素。校园环境也受到了道路交通污染的直接影响。本文应用COPERT模式对校园周边道路的尾气进行了定量的分析。实验区域为华南师范大学周边四条主要街道(中山大道、五山路、翰景路和华南快速干线)。通过采集四个时间段(8:30~8:45 am12:00~12:15 pm15:00~15:15 pm18:00~18:15 pm)的车流量数据,计算了相应的CONOxVOCPM的排放因子及排放量,并对各种污染物的排放特征进行了分析。分析结果表明CONOxVOCPM各自在四个时间段排放量总量为61.612 kg29.519 kg7.650 kg1.470 kg8:30~8:45 am18:00~18:15 pm时段各污染物的排放量较高。

On-road traffic emissions have become a source of urban air pollution and will directly affect the environ- ment of campus. In this paper, traffic emissions in streets around campus are calculated by the COPERT model. The experimental area is the four streets (Zhongshan Road,Wushan Road,Hanjing Roadand South China Expressway) surroundingSouthChinaNormalUniversity. Traffic data are collected at four time periods (8:30-8:45 am, 12:00-12:15 pm, 15:00-15:15 pm and 18:00-18:15 pm). Vehicle emission factors and the amount of CO, NOx, VOC and PM are cal- culated. Then, emission characteristics are analyzed. The result shows that the total emissions of CO, NOx, VOC, PM in the four time periods are 61,612 kg, 29.519 kg, 7.650 kg and 1.470 kg respectively. By comparing the four time periods, it is found that each pollutant emissions in 8:30-8:45 am and 18:00-18:15 pm are higher than the other two time periods.
