摘　　要：利用自行研制的开放光程傅里叶变换红外光谱测量系统于2008奥运期间对北京燕山地区大气中的HCHO,CH_4,CH_3OH,C_2H_6,C_2H_4,C_2H_2和CH_3COCH_3气体进行了连续监测,介绍了系统的组成及光谱数据处理方法,并对浓度测量结果进行了分析。研究结果显示,7月20日限行措施实施后,除C_2H_4外,其他气体日平均浓度均有明显下降,平均幅度约29%,奥运期间平均降幅达34%,受局部气象条件引起的本底浓度暂时性波动影响,监测指标物中,C_2H_4平均浓度分别增加6.09%和19.66%,但其日变化幅度明显下降,表明北京市奥运期间的控制减排措施有效。An open path Fourier transform infrared spectroscopy system which measured the ambient concentrations of multi-gas in Yanshan area of Beijing during 2008 Beijing Olympic Games is presented. The quantitative analysis model used for the determination of the concentration of the unknown species is described. The measured results show that, most of the gases were decreased during the traffic controlling （-29%） and the period of Olympic Games （-34%）. With the influence of background concentration, C2H4 increased of 6.09% and 19.66% during the traffic controlling and the period of Olympic Games. However, the typical diurnal variation shows the emission of C2H4 was reduced significantly.
