  • 摘要: 为探究兰州市近地面臭氧(O3)浓度的分布特征,对2013~2016年兰州市5个国家空气质量监测点逐时的O3浓度资料进行了统计分析,结合同期的NO2和颗粒物(PM10、PM2.5)浓度资料得到兰州市的O3污染变化趋势及其分布特征。结果表明:兰州市区O3与NO2浓度的日变化呈现相反的变化趋势,二者之间存在明显的负相关关系,相关系数为-0.45;兰州市区颗粒物与O3之间相互影响,颗粒物浓度春、冬季较高,而O3夏季较高,O3与PM2.5浓度月变化之间的相关系数为-0.78,O3逐渐成为继颗粒物之后首要污染物天数最多的污染物;兰州市区和榆中县O3浓度均呈现明显的日变化、月际变化、季节变化;不同站点分布特征显示,兰州市区4个监测站点中兰炼宾馆O3浓度最高,职工医院与生物制品厂相差不大,铁路设计院最低,表明西固区O3污染形势最为严峻,七里河区次之,城关区O3污染较轻,而且榆中县O3浓度除夏季外其它时段均比市区高。
    Abstract: In order to explore the distribution characteristics of near-surface ozone (O3) concentration in Lanzhou city, the hourly O3 concentration data of five national air quality monitoring sites in Lanzhou from 2013 to 2016 were statistically analyzed. Combined with the data of NO2 and particulate matter (PM10 and PM2.5) concentration in the same period, the variation trend and distribution characteristics of O3 pollution in Lanzhou were obtained. The results indicated that the daily variation of O3 and NO2 concentrations in Lanzhou City showed an opposite trend, and there was a significant negative correlation between them with correlation coefficient of-0.45. Particulate matter and O3 interacted with each other in Lanzhou city. The concentration of particulate matter were higher in spring and winter, while O3 was highter in summer. The correlation coefficient between O3 and PM2.5 concentration was-0.78. O3 gradually became the most important pollutant after the particulate matter. The O3 concentrations in Lanzhou city and Yuzhong county showed obvious diurnal, monthly and seasonal variations. The distribution characteristics of different sites showed that Lanlian Hotel had the highest concentration of O3 in four monitoring sites in Lanzhou city. There was little difference between the staff hospital and biological products factory, and the railway design institute was the lowest. This result indicated that the O3 pollution situation in Xigu District was the most serious, followed by the Qilihe District and Chengguan District. The O3 concentration in Yuzhong county was higher than that in the urban area except for summer.
