摘　　要：该研究通过构建2020年中国燃煤工业锅炉CO_(2)与大气污染物排放清单,分析燃煤工业锅炉碳污排放现状及时空分布特征,通过分析2000-2020年燃煤工业锅炉碳污排放变化规律,揭示了活动水平及污染物控制技术对燃煤工业锅炉碳污排放的影响。研究表明,2020年燃煤工业锅炉总细颗粒物、可凝结颗粒物、可过滤细颗粒物、可过滤可吸入颗粒物、SO_(2)、NO_(x)、CO、CO_(2)、NH_(3)及VOCs分别排放25.36万t、17.54万t、7.82万t、25.3万t、49.03万t、35.64万t、205万t、3.63亿t、977 t及3.52万t,排放强度较高的区域主要分布于黑龙江、吉林、辽宁以及内蒙古,并呈现秋冬季排放显著高于春夏季的特点。2000-2020年中国燃煤工业锅炉碳污排放均呈现先升高后降低的趋势,峰值出现在2011年前后而2020年为最低。活动水平在长时间碳污排放趋势中呈现主导性作用,其中以热电联产为主的供热格局是近年来主要的驱动因素。污染物控制技术提升对抑制排放量峰值、持续降低污染物排放具有重要意义,尤其对于可过滤颗粒物(FPM)的驱动作用明显。由于原煤供热的成本显著低于其他方式,环境政策在该期间起到至关重要的作用。此外,尽管燃煤工业锅炉CO_(2)排放已经显著下降,但是供热部门整体的CO_(2)排放并未显著下降。This study established CO_(2)and air pollutants emission inventory from coal-fired industrial boilers(CFIB)in China in 2020,which reflect the current spatial-temporal characteristics of CO_(2)and air pollutants emissions from CFIB.The temporal variation of CO_(2)and air pollutants emission from CFIB from 2000 to 2020 were analyzed,and the influence of activity level(AL)and air pollutant control devices(APCD)on CO_(2)and air pollutants emission was revealed.The result shows that in 2020,the total fine particulate matter,condensable particulate matter,filter fine particulate matter,FPM_(10),SO_(2),NO_(x),CO,CO_(2),NH_(3)and VOCs of CFIB emit 253600 tons,175400 tons,78200 tons,253000 tons,490300 tons,356400 tons,2.05 million tons,363 million tons,977 tons and 35200 tons respectively,mainly distributed in the provinces of Heilongjiang,Jilin,Liaoning and Inner Mongolia,and the emission in autumn and winter is significantly higher than that in spring and summer.From 2000 to 2020,the CO_(2),emission of CFIBs in China present an inverted U-shaped trend,with the peak appearing around 201l and the lowest in 2020.AL plays a dominant role in the long-term trend of CO_(2)and air pollutants,and the heating pattern based on cogeneration is the main driving factor in recent years.The improvement of APCD is of great significance to restrain the peak emissions and reduce pollutant emissions,especially for the filterable fine matter particles.Because the cost of coal heating is significantly lower than other ways,the role of environmental policy during this period is decisive.In addition,although CO_(2)emissions from CFIB have decreased significantly,the CO_(2)emissions in heating sectors did not decrease significantly.
