摘要: 应用AERMOD模型,基于葫芦岛市2016年污染源排放清单和相关参数,模拟了葫芦岛市SO2和NO2的地面浓度,并与葫芦岛市4个大气环境监测站的对应资料进行对比验证。结果表明:SO2和NO2模拟的平均值均略小于监测值,造成这种差异的原因较多,但主要原因是模拟中所用的污染源排放清单还不够完善。而SO2的监测和模拟结果的相关性比NO2略好,其中SO2总的相关系数的平均值为0.71,而NO2为0.64;4个监测点位SO2总的平均值的相对误差为-19.4%,4个监测点位NO2总的平均值的相对误差为-25.6%。在SO2的模拟结果中,冬季和春季监测和模拟结果的相关性相对较好,其中冬季监测和模拟结果的相关系数平均值为0.79;而NO2的模拟结果中,冬季和秋季监测和模拟结果的相关性相对较好,其中冬季监测和模拟结果的相关系数平均值为0.69。

Abstract: Using the AMS/EPA Regulatory Model (AERMOD) and information on the emission inventory and relevant parameters of pollutant sources in Huludao city during 2016,the surface SO2 and NO2 concentrations were simulated and the results were validated with the observational data from four atmospheric environmental monitoring stations in Huludao.The results show that the simulated mean concentrations of SO2 or NO2 are slightly smaller than observational values,and the major one among various reasons is that the emission inventory in the model is not perfect.The correlation between the simulated and observational concentrations of SO2 is relatively better than that of NO 2,with the mean value of correlation coefficient of 0.71 for SO2 and 0.64 for NO2.The relative er-ror of the simulated concentration of SO 2 averaged at four monitoring stations is -19.4% and that of NO2 is -25.6%.The correlation between the simulated and observational SO 2 in winter and spring is better than other sea-sons,with the correlation efficient of 0.79 in winter.While the correlation between the simulated and observational NO 2 in winter and autumn is better,with the correlation efficient of 0.69 in winter.
