摘　　要：以天水市境国道310线排放的汽车尾气污染源成分中的一氧化碳(CO)和氮氧化物(NOX)为研究对象,利用公路线源源强计算公式,选取三种不同的污染物单车排放因子分别计算CO和NOX的排放强度,并根据计算结果分析三种计算方法的差异性以及产生这种差异的原因。结果表明:在公路项目环境影响评价工作中排放因子取值具有盲目性,导致计算得出的公路线源源强具有较大的差异性。In this paper, carbon monoxide （CO）and nitrogen oxides （NOx） in the automobile exhaust pollution source from State Road 310 line in the territory of Tianshui as the research object, by adopting the highway line source strength calculation formula, three different kinds of vehicle emission factors are selected to respectively calculate the emission intensity of CO and NOx and to analyze the differences of three kinds of calculation methods and the reasons for the differences according to the results. The result shows that： it is blindness to select the emission factor in environmental impact evaluation of highway project, so it leads to large difference of highway line source strength.
