摘　　要：基于CAMx模型的PSAT颗粒物源示踪技术,对2016年济南都市圈PM_(2.5)污染、区域传输规律及行业贡献进行了定量分析。结果表明:从PM_(2.5)年均来源贡献率看,济南市本地排放约占50%,来自济南都市圈总贡献率约占75%。圈内城市间相互贡献明显,最高达13%。夏季,本地贡献最大,区域传输中鲁东地区对研究区域影响最高,为24%;受冬季季风影响,来自京津冀方向的区域传输增多,最高达24%。目前,对济南都市圈PM_(2.5)贡献较大的污染源为工业锅炉、钢铁、扬尘源、化工、冶金、建材行业和机动车,有针对性地削减上述污染源排放,可达到快速、有效降低PM_(2.5)浓度的目的。Based on the PSAT particulate source tracing technology of camx model,the quantitative analysis of PM_(2.5)pollution,regional transport law and sector contribution for cities over Jinan Metropolitan Area were performed for year 2016.The results showed that in terms of the annual mean source apportionment of PM_(2.5),for the local area of Jinan City,the emission accounted for about 50%,while the whole Jinan Metropolitan Area contributed 75%.The mutual contributions among Jinan Metropolitan Area cities were obvious,up to 13%.In summer,the local contribution was the largest and the regional transport in the eastern Shandong region had the highest impact on the study area by 24%.While in winter,affected by the winter monsoon,the regional transport from Beijing-Tianjin-Hebei Region increased,up to 24%.At present,as far as Jinan Metropolitan Area was concerned,the major sectors contributed to PM_(2.5)included industrial boilers,steel industry,fugitive dust,chemical industry,metallurgical industry,building material industry,and automobile source.The targeted counter-measure for the above sectors may be a fast and effective approach to reduce PM_(2.5)pollution.
