摘　　要：利用车载被动DOAS测量系统,对某钢铁企业进行分装置绕行观测。采用了计算参与拟合截面相关性的方法,确定痕量气体最优反演波段,获取观测路径上的垂直柱浓度后,结合测量时间内的车速以及风速风向信息,计算得出区域内SO_2及NO_2排放净通量。实验得出该钢铁企业厂区内轧钢冶炼区域SO_2与NO_2排放净通量均值分别为149 kg/h和372 kg/h,焦化区域为260 kg/h和286 kg/h,电厂区域为21 kg/h和26 kg/h,石灰烧培区域为64 kg/h和79 kg/h,烧结区域为34 kg/h和99 kg/h。Mobile passive differential optical absorption spectroscopy （DOAS） was used for the remote sensing of the emission flux from different systems of a steel factory. Correlation matrix of the absorption cross sections was used for the best DOAS inversion band. Vertical column density was retrieved by this system, combined with the meterorological wind field and car speed information,the emission of SO2 and NO2 in the area was estimated. The results showed that the average value of the flux of SO2 and NOr was 149 kg/h and 372 kg/h in the rolling and smelting system, 260 kg/h and 286 kg/h in the coking system, 21 kg/h and 26 kg/h in the power system, 64 kg/h and 79 kg/h in the roasting system, and 34 kg/h and 99 kg/h in the sintering system.
