摘要
为了评估APEC会议期间严格的交通扬尘控制措施的效果,选取北京地区不同类型道路,在会议之前和会议期间分别采集40个道路积尘负荷样品,并调研了道路车流量及车型比例等机动车活动水平变化.采用AP-42方法计算不同类型道路PM10排放因子和排放强度,基于Arc GIS平台应用自下而上的方法建立了排放清单,分析交通扬尘PM10排放的空间分布特征,评估APEC会议期间北京市道路交通扬尘控制效果.结果表明:APEC会议期间北京市日均车流量减少12%,快速路、主干道、次干道、支路、郊区道路的积尘负荷分别下降31%、58%、73%、54%和46%,PM10排放因子分别下降63%、67%、86%、63%和40%,排放强度分别下降73%、71%、87%、78%和49%.在空间分布上,城区道路交通扬尘PM10排放量减少77%,郊区道路减少49%.
In order to evaluate the effectiveness of control measures for fugitive dust,forty silt loading samples from different types of paved roads were collected before and during the APEC meeting in Beijing region. The activity level data such as traffic volume and vehicle type composition before and during the APEC meeting were investigated and compared. Road fugitive dust emission factors and emission strength of Beijing were calculated following the US EPA AP-42 methodologies,and emission inventory was developed using bottom-up approach on Arc GIS platform. The spatial distribution of road fugitive dust emissions were analyzed,and the effectiveness of road fugitive dust control during the APEC in Beijing were evaluated. The results showed that during the APEC meeting,with 12% decrease of daily traffic volume,the silt loading,PM10 emission factors and PM10 emission strength were reduced by 31%,58%,73%,54% and 46%,63%,67%,86%,63% and 40%,and 73%,71%,87%,78% and 49% for freeways,major arterial,minor arterial,collector and suburb roads,respectively. In view of the spatial distribution,PM10 emissions from road fugitive dust were reduced by 77% and 49% for urban roads and suburb roads,respectively.
