摘 要:通过收集荆门市“十三五”期间5个国控监测点的大气监测数据,分析荆门市大气质量变化趋势及污染成因。结果表明:荆门市空气污染的主要来源为颗粒物(PM_(2.5)和PM_(10)),两者对城市空气污染总体贡献率超过50%;其次为O_(3),贡献占比在13%-23%之间,污染物的年均负荷系数顺序分别为:PM_(2.5)>PM_(10)>O_(3)>NO_(2)>CO>SO_(2)。荆门市SO_(2)、NO_(2)、CO和O_(3)年均值均低于国家《环境空气质量标准》(GB3095-2012)二级标准限值,除2020年的PM_(10)年均值达标之外,PM_(2.5)和PM_(10)均超国家二级标准限值。其中,SO_(2)和CO两种污染物季节变化不明显,而PM_(2.5)、PM_(10)、NO_(2)和O_(3)四种污染物呈现明显季节变化趋势。本文提出的对策建议对我国城市大气环境管理具有一定的参考价值。It collected five air monitoring data from national-controlled monitoring points in Jingmen City during the 13th Five-Year Plan period and analyzed the changing trends of air quality and the causes of pollution in Jingmen City.The results have shown th at the main sources of air pollution in Jingmen city were particulate matter(PM_(2.5)and PM_(10)),which contributed more than 50%to the overall air pollution in the city,followed by O;which contributed between 13%and 23%.The average annual load coefficient of pollutants is in the following order:PM_(2.5)>PM_(10)>O_(3)>NO_(2)>CO>SO_(2).The concentrations of SO_(2)、NO_(2)、CO and O_(3)in Jingmen City below the limits of the national secondary standard limits(GB3095-2012).Except for the annual average value of PM_(10)in 2020,both PM_(2.5)and PM_(10)exceeded the national secondary standard limit.Among them,the seasonal changes of SO_(2)and CO are not obvious,while the four pollutants of PM_(2.5)、PM_(10)、NO_(2)andO_(3)have obvious seasonal changes.The corresponding countermeasures and suggestions have certai n reference value for urban air environment management.
