摘要
道路积尘负荷表征路面清洁程度,是道路扬尘排放清单中一个十分重要的参数,也是各地环境管理的一个重要方面。根据AP-42道路扬尘排放因子模型,2015年春季用真空吸尘法采集了天津市11条道路的扬尘样品,得到了不同道路类型以及不同车道的积尘负荷,并分析了积尘负荷的变化规律。结果表明:天津市春季非机动车道和机动车道慢车道的积尘负荷分别为0.282 0~1.064 5 g/m^2和0.050 4~0.173 9 g/m^2;5种道路类型的非机动车道的积尘负荷中位值均大于机动车慢车道积尘负荷的中位值;对于不同道路类型积尘负荷而言,非机动车道从大到小顺序依次为次干道>主干道>环线>支路>快速路,机动车道慢车道从大到小顺序依次为次干道>环线>主干道>支路>快速路;东西走向和南北走向道路两侧积尘负荷差异均无统计学意义。
The silt loading can characterize the road cleaning degree, and it＇s a very important parameter of road dust emission inventory, also an important aspect in the local environment management. According to the AP-42 model, the study collected road dust samples on 11 roads in Tianjin with vacuum aspiration method in the spring of 2015. The silt loading of different lanes and different road types were obtained, and its variation was analyzed. The results were as follows： The road dust silt loading of non-motor vehicle lanes ranged from 0. 2820 to 1. 0645 g/m^2 ; The silt loading of motor vehicle lanes were between 0. 0504 and 0. 1739 g/m^2. The median values of non-motor vehicle lanes were bigger than of motor vehicles lanes for the five road types. The silt loading distribution of both non-motor vehicle lanes and motor vehicle lanes as follows： Non-motor vehicle lanes minor arterial 〉 major arterial 〉 outer ring 〉 branch road 〉 express way, motor vehicle lanes minor arterial 〉 outer ring 〉 major arterial 〉 branch road 〉 express way ; There was no significant difference for the silt loading between two sides of east-west and north-south roads.
