在发展中地区，特别是污染严重的北方地区，准确估算家用固体燃料燃烧的污染物排放量一直是一个具有挑战性的问题。在对北京市所有农村居民家庭能源使用情况进行调查的基础上，建立了北京市农村居民家庭燃烧产生的PM2，5、SO2、NOx和NMVOCs的排放清单，并提出了3种排放控制方案。值得注意的是，2015年家庭取暖和做饭分别使用了3805千吨和556千吨煤炭。2015年，家庭供暖的NOx、NMVOCs、SO2和PM（2，5）排放量分别为11.51kt、29.3kt、43.1kt和34.7kt，而家庭烹饪的排放量分别为1.55kt、4.02kt、6.55kt和3.99kt。冬季家庭取暖排放的PM2.5占总排放量的70%，SO2占总排放量的60%。此外，北京市中心被污染严重的郊区所包围。禁煤政策（如“煤改气”）可以逐步改善北京市区的空气质量。(C)2018爱思唯尔有限公司版权所有
Accurate estimation of pollutant emissions from household solid fuel combustion has been a challenging issue in developing regions, especially in the heavily polluted northern China region. Basing on a survey of residential household energy use in all villages in Beijing, this study developed a village-based emission inventory of PM2,5, SO2, NOx, and NMVOCs emitted from household combustion in Beijing, as well as three emission control scenarios. Notably, 3805 kt and 556 kt of coal were used for household heating and cooking in 2015, respectively. The emissions of NOx, NMVOCs, SO2, and PM(2,5)forhousehold heating totaled11.51ct, 29.3 kt, 43.1 kt, and 34.7 kt in 2015, respectively, while those for household cooking totaled 1.55 kt, 4.02 kt, 6.55 kt, and 3.99 kt. Emissions from household heating contributed to-70% of PM2.5 and similar to 60% of SO2 emissions in winter. Additionally, downtown Beijing is surrounded by polluted suburbs. A coal forbiddance policy (e.g. "coal to gas") could gradually improve the air quality in urban Beijing. (C) 2018 Elsevier Ltd. All rights reserved.
