中文摘要:
      以四川省南充市为研究区域,通过实地调研、现场测试及结合统计年鉴等获得数据,采用排放因子法计算南充市2014年大气PM10、PM2.5排放量并建立排放清单。结果表明,南充市2014年扬尘源、移动源、生物质燃烧源、化石燃料固定燃烧源、工艺过程源排放总量PM10分别为85 187、1 777、9 175、2 417、3 519 t,PM2.5分别为16 093、1 619、7 322、914、1 585 t,PM10贡献率分别为83.5%、1.7%、9.0%、2.4%、3.4%,PM2.5贡献率分别为58.4%、5.9%、26.6%、3.3%、5.8%。城市区域扬尘源、生物质燃烧源、移动源、化石燃料固定燃烧源、工艺过程源对PM10贡献分别为60.0%、12.5%、6.3%、8.6%、12.5%,对PM2.5贡献分别为41.8%、21.6%、14.4%、8.1%、14.1%。南充市2014年大气PM10、PM2.5排放源总量和贡献率以及区域空间分布特征均存在差异。
英文摘要:
      The emitted amounts of PM10 and PM2.5 in Nanchong in 2014 were calculated and the emission inventory was built by using the emission factor method with data of field instigation, field test and statistical yearbook. Results showed that the total PM10 emission of dust, moving source, biomass combustion, fossil fuel combustion and process engineering sources in 2014 in Nanchong was 85187, 1777, 9175, 2417 and 3519 t, PM2.5 was 16093, 1619, 7322, 914 and 1585 t, and PM10 contribution was 83.5%, 1.7%, 9.0%, 2.4% and 3.4%, PM2.5 contribution was 58.4%, 5.9%, 26.6%, 3.3% and 5.8%, respectively. Dust was the most important emission sources, road dust accounted for the most, especially the country roads without paved. Biomass combustion and road moving were also important emission sources. The emission contribution of dust, moving source, biomass combustion, fossil fuel combustion and process engineering sources of PM10 in the city area was 60%, 12.5%, 6.3%, 8.6% and 12.5%, the contribution to PM2.5 was 41.8%, 21.6%, 14.4%, 8.1% and 14.1%, respectively. The total amount contributions and the spatial distribution characteristics of PM10 and PM2.5 emission sources in Nanchong in 2014 were different.
