摘　　要：对EPA推导AP-42模型的源数据划分范围,评估不同积尘负荷范围的线性回归模型的模拟效果。结果显示,在不同积尘负荷范围内（0～0.5、0.5～1、0～1、0～4和5～400 g/m2）,线性回归模型参数以及方程R2值均有差异。对182个北京市道路积尘样品进行频数分布分析,发现积尘负荷主要分布在0～0.5 g/m2或0～1 g/m2范围内,分别运用道路积尘负荷0～0.5、0.5～1和0～1 g/m2范围的模拟回归模型,评估北京市铺装道路PM10的排放特征,尽管3个不同模型评估结果的平均值的比例是4∶2∶1,但是3个模型评估不同类型道路PM10排放因子的大小顺序是：支路〉次干道〉主干道〉快速路。The source data of AP-42 modeling and inventories（ the compilation of air pollutant emission factors） compiled by the U. S. Environmental Protection Agency was divided into different ranges of silt loading,and the simulation effects of linear regression modeling for every range were evaluated. The results showed that there were discrepancies both in parameters of the linear regression models and the value of R2 from the equations in the silt loading range of 0 to 0. 5,0. 5 to 1,0 to 1,0 to 4 and 5 to 400 g / m2,respectively. It was found that the distribution of silt loading was mainly between 0 to 0. 5 g / m2 or 0 to 1 g / m2 according to the frequency distribution analysis of silt loading samples,which were sampled from 182 different roads in Beijing,China. The PM10 emission characteristics of paved roads in Beijing were evaluated using the simulated regression model for the silt loading range of 0 to 0. 5,0. 5 to 1 and 0 to 1 g / m2,respectively. Although the ratio of the average assessment values from three different models was 4 ∶ 2 ∶ 1,the PM10 emission factors decreased similarly across different road types in the order collector〉 minor arterial〉 major arterial 〉freeway.
