| 摘 要： | 于2016～2017年四季在烟台市3个点位采集了PM_(2.5)样品,分析了其质量浓度和化学组分特征.利用CMB模型对受体进行解析,并利用后向轨迹和PSCF对传输气流和潜在源区进行了分析.结果表明,烟台市监测点位冬季、春季、夏季和秋季的PM_(2.5)平均质量浓度分别为(89. 45±56. 80)、(76. 78±28. 44)、(32. 65±17. 92)和(57. 32±24. 60)μg·m~(-3). PM_(2.5)浓度表现出明显的季节变化特征(P 0. 01).全年PM_(2.5)各源类分担率大小依次为:二次硝酸盐源(20. 3%)城市扬尘源(15. 7%)机动车排放源(14. 9%)燃煤源(13. 8%)二次硫酸盐源(12. 8%) SOC(6. 1%)建筑水泥尘源(5. 5%)海盐源(2. 9%),可以看到烟台市以二次源、扬尘、机动车排放源和燃煤源为主要污染源.春季硝酸盐源和城市扬尘源是重要贡献源类,夏季硫酸盐源贡献突出,燃煤源在秋冬季占比突出.烟台市气流输送和潜在源区也呈现出明显的季节变化:冬季主要受烟台市短距离输送的影响;夏季主要受烟台东部沿海和本地的影响;春秋季主要受山东东北部和东部沿海地区的区域传输和烟台市本地源的影响.
