摘要: Abstract The PM2.5 concentration of the air pollution transmission channel cities (APTCC) Beijing-Tianjin-Hebei area (“2 + 26” cities) is significantly higher in heating season than non-heating season. Space northern China involves substantial fossil fuel combustion that produces haze-generating pollutants. In order to improve atmospheric environment, it necessary quantitatively analyze pollutants generated by such heating. this study, emission factors several common heat sources, as combined and power (CHP), boilers, rural biomass stoves, scattered coal-heating are analyzed classified into direct emissions indirect emissions. Direct refer all locally source due combustion, whereas those elsewhere electricity consumption. “2 + 26” then divided six small urban agglomerations cluster analysis, supply various sources investigated. Finally, pollutant intensity calculated per unit land for each agglomeration 2016. This study shows Beijing Tianjin other agglomerations, many agglomerations. proposes suggestions clean reduce
