摘　　要：通过对大庆市主要交通干线大气中非甲烷总烃的测定,得出了大庆市主要交通干线大气中非甲烷总烃的分布规律。结果表明,大庆市主要交通干线大气中非甲烷总烃的浓度日变化存在明显的双峰规律,从时段分布来看,上午8:00左右,下午17:00左右各出现一次峰值浓度;从季节分布来看,冬季浓度略高于夏季;交通干线上各点位非甲烷烃浓度略有差异。We determined Total non methane hydrocarbon in main traffic trunk lines of Daqing city and found out distribution rule of it. Results showed that there was an obvious bimodal rule in the diurnal variation of concentration of NMHC. From the point of time distribution, peak concentrations appeared around 8：00 AM and around 17：00 PM respectively. From the point of seasonal distribution, winter concentration was slightly higher than the summer. Concentrations of NMHC in different monitoring sites varied slightly.
