摘　　要：选取天津市汽车制造、家具制造、包装印刷及医药制造等13个VOCs重点行业,通过实测法构建了工业源本地化VOCs成分谱,并基于大气模型化学机理CB05和SAPRC99建立了本地化物种谱,且与美国环保署SPECIATE数据库中的物种谱进行对比分析,通过空气质量模型验证不同大气化学机制对O3生成的影响.结果表明:(1)基于SAPRC99机制建立的本地化物种谱与SPECIATE的差异要显著高于CB05机制.(2)汽车制造、家具制造、乐器制造、涂料生产、汽车零部件制造、轮胎制造行业物种谱差异较小,包装印刷、医药制造等其它行业差异较为显著.(3)不同模式大气气相化学机制对O3的模拟结果的变化趋势总体一致,不存在显著性差异,但SAPRC99机制模拟结果略高于CB05机制,建议当本地化VOCs成分谱缺失或不详尽时,优先考虑采用CB05机制.The VOCs chemical species profiles from industrial sources in Tianjin were established by field sampling method based on 13major VOCs-related industries including automobile manufacturing,furniture production,packaging&printing,pharmaceutical industry,etc.The local model-ready source profiles were further established based on chemical mechanism CB05 and SAPRC99,and then compared to those from SPECIATE in EPA.The influence of different atmospheric chemistry mechanisms on O3generation was verified by photochemical air quality model.The results showed that:the model-ready source profiles based on SAPRC99have a large deviation from SPECIATE than that based on CB05.There were relatively fewer differences in local model-ready sources profiles among automobile manufacturing,furniture production,musical instrument manufacturing,coating producing,automotive components manufacturing and tire manufacturing,while more significant differences were revealed in package printing,pharmaceutical manufacturing and other industries.Variation tendencies of the simulation results of O3 by different atmospheric chemical mechanisms showed similar results,while the simulation results based on SAPRC99were slightly higher than that based on CB05.Therefore,it is suggested to employ the CB05when lack of local VOCs source profiles.
