  • 摘要: 为研究贵阳市大气臭氧的光化学生成特征，于2016年选取大气臭氧浓度较高的时段，在城区和郊区环境空气质量监测点对贵阳非甲烷烃类的环境浓度进行了观测.并利用基于观测的光化学模型分析了贵阳近地面大气臭氧生成的典型光化学过程和敏感性.通过在臭氧浓度较高时段，对比分析城区和郊区臭氧和臭氧前体物、模拟的主要自由基和光化学链反应终止产物的变化特征，发现贵阳城区与郊区的臭氧生成特征不同.通过分析臭氧主要前体物的相对增量反应活性，进一步发现城区臭氧生成主要受VOCs控制，郊区主要受NOx控制.控制人为源的烯烃和芳香烃对于控制城区臭氧污染最为有效.
    Abstract: In order to study the photochemical production characteristics of atmospheric ozone in Guiyang City, the concentration of non-methane hydrocarbons in Guiyang was observed at air quality monitoring stations in urban and suburban areas during 2016 when the atmospheric ozone concentration was high. Using the observation-based photochemical model, the typical photochemical processes and sensitivities of atmospheric ozone production near the ground surface were analyzed. By comparing the characteristics of ozone and ozone precursors, simulating the concentrations of the main free radicals and the photochemical chain products in urban and suburban areas, it was found that the characteristics of ozone production in urban and suburban areas of Guiyang were different. By analyzing the relative incremental reactivity of the major precursors of ozone, it was further found that the urban ozone production was mainly controlled by VOCs, and the suburbs were mainly controlled by NOx. The control of anthropogenic alkenes and aromatics is most effective in controlling urban ozone pollution.

摘要: 为研究贵阳市大气臭氧的光化学生成特征，于2016年选取大气臭氧浓度较高的时段，在城区和郊区环境空气质量监测点对贵阳非甲烷烃类的环境浓度进行了观测.并利用基于观测的光化学模型分析了贵阳近地面大气臭氧生成的典型光化学过程和敏感性.通过在臭氧浓度较高时段，对比分析城区和郊区臭氧和臭氧前体物、模拟的主要自由基和光化学链反应终止产物的变化特征，发现贵阳城区与郊区的臭氧生成特征不同.通过分析臭氧主要前体物的相对增量反应活性，进一步发现城区臭氧生成主要受VOCs控制，郊区主要受NOx控制.控制人为源的烯烃和芳香烃对于控制城区臭氧污染最为有效.
