摘要:

于2023年1—2月选取德阳市大气超级站作为观测点对德阳市冬季细颗粒物（PM_2.5）进行了监测，采用正矩阵因子分解（PMF）模型对德阳市冬季PM_2.5特征及来源进行了分析。结果表明，德阳市冬季大部分PM_2.5污染源来源于本地排放，PM_2.5组分中以有机物、硫酸盐、硝酸盐和铵盐等物质为主；污染来源贡献中二次气溶胶占比最高（38.0%），然后依次为移动源（27.1%）、生物质燃烧（11.3%）、固定燃烧源（11.0%）、工业生产（5.7%）、扬尘源（4.6%）和烟花爆竹（2.3%）。从管控的角度来看，德阳市冬季应重点加强移动源和燃烧源的管控，施行源头治理、绿色出行；重点节假日明确烟花爆竹的禁燃地点和时间等措施。

Abstract:

In January and February 2023， Deyang Atmospheric Super Station was selected as the observation site to monitor the fine particulate matter（PM_2.5） in winter in Deyang， and the characteristics and sources of PM_2.5 in winter in Deyang were analyzed by using the positive matrix factorization（PMF） model. The results show that most of the PM_2.5 pollution sources in winter in Deyang come from local emissions， and PM_2.5 components are mainly organic matter， sulfate， nitrate， and ammonium salt. Secondary organic aerosol accounts for the highest contribution of pollution sources（38.0%）， followed by mobile sources（27.1%）， biomass combustion（11.3%）， fixed combustion sources（11.0%）， industrial production（5.7%）， dust sources（4.6%）， and fireworks and firecrackers（2.3%）. From the point of view of control， Deyang should focus on strengthening the control of mobile sources and combustion sources in winter， implementing source management and green travel， as well as taking measures such as defining the place and time for setting off fireworks and firecrackers during key holidays.
