摘　　要：近年来,播州城区臭氧浓度呈现逐渐上升趋势,可能对市民健康和生态环境高质量考核产生影响。为弄清播州城区环境空气臭氧污染的来源,对气象条件、区域传输、前体物VOCs等方面进行了分析,其中气象条件统计分析、区域传输采用拉格朗日粒子扩散模型、前体物VOCs检测采样OPF计算分析,识别了臭氧形成产生影响的主要原因,结果表明:臭氧的形成的原因是气象条件、区域传输、主要前体物VOCs等导致了臭氧浓度增加。提出了播州城区城市环境空气质量要遏制臭氧浓度增加趋势,需要从不利气象条件下管理、应急管控联动、交通综合管控、秸秆综合利用禁烧等方面着手。In recent years,the ozone concentration in Bozhou city has shown a gradually increasing trend,which may have an impact on the quality assessment of public health and ecological environment.In order to understand the source of ambient air ozone pollution in Bozhou urban area,this paper analyzes and studies meteorological conditions,regional transmission,precursor VOCs and other aspects.Among them,statistical analysis of meteorological conditions,Lagrange particle diffusion model for regional transmission,and calculation and analysis of precursor VOCs detection and sampling OPF are used to identify the main causes of ozone formation.It is concluded that the causes of ozone formation are meteorological conditions,regional transmission and the main precursor VOCs,which lead to the increase of ozone concentration.The results indicate that in order to curb the increasing trend of ozone concentration in Bozhou city,it is necessary to start from the aspects of management under unfavorable meteorological conditions,emergency control linkage,comprehensive traffic control,comprehensive utilization of straw and so on.
