中文摘要:
      选取衡阳市区和衡山背景站臭氧自动监测数据,分析两地的臭氧污染特征。对空气质量的优良率情况、臭氧作为首要污染物的变化情况、臭氧浓度的日变化特征、典型时段的浓度变化特征、臭氧浓度的月际变化特征和臭氧与PM2.5的关联情况等进行了分析。结果表明,多云及阴雨天气时,衡阳市区的臭氧浓度日变化幅度大于衡山背景站。夏季,衡阳市区和衡山背景站的臭氧浓度的日变化特征规律差异较大,臭氧浓度分布比较分散,前者为典型的单峰形,后者则波动平缓。冬季,日变化幅度不大,但衡阳市区的臭氧浓度明显低于衡山背景站。衡山背景站和衡阳市区的臭氧基本同步变化,但日均值高于衡阳市区。
英文摘要:
      The ozone automatic monitoring data of Hengyang and Heng Mountain background station were selected to analyze the characteristics of ozone pollution. The excellent rate of air quality, the change of ozone as the primary pollutant, the daily variation of ozone concentration, the characteristics of the concentration change in the typical time period, the monthly change characteristics of the ozone concentration and the relationship between ozone and PM2.5 were analyzed in this paper. The results showed that the daily variation of ozone concentration of Hengyang station was larger than that in Heng Mountain background station with cloudy, overcast and rainy weather. In summer, the daily variation of ozone concentration in Hengyang and Heng Mountain background background stations were quite different. The distribution of ozone concentration was relatively scattered. The former was a typical single peak type while the latter fluctuated gently. In winter, the daily variation was not obvious, but the ozone concentration in Hengyang station was significantly lower than that in Heng Mountain background station. The ozone level at Heng Mountain background station and Hengyang urban area basically changed synchronously, but the daily average value was higher than that in Hengyang city.
