摘　　要：本研究基于2018年火电在线监测和环境统计等数据,自下而上编制了中国高分辨率火电行业排放清单,并核算了排放浓度、排放因子和排放量.结果表明超低排放政策效果显著:2018年火电SO2、NOx和烟尘平均排放浓度分别为37.57、56.71和7.41mg·m^-3.比2015年分别下降58.71%、43.12%和60.79%;中国燃煤机组的SO2、NOx和烟尘平均排放因子分别为0.30、0.48和0.06 g·kg^-1,比2015年分别下降55.2%、36.84%和62.5%;中国火电SO2、NOx、烟尘和PM2.5总排放量分别为72.14、118.38、14.90和13.59万t·a^-1,比2015年分别下降41.32%、19.29%、48.12%和40.39%.This study updates a bottom-up high-resolution emission inventory and estimates the concentrations,emission factors,emissions,and performance values of China’s power plants,based on the data from continuous emission monitoring systems and environmental statistics in 2018.The results show that the ultra-low emission policy has significant effects:the average concentrations of SO2,NOx,and PM in thermal power plants were 37.57,56.71,and 7.41 mg·m^-3,respectively in 2018,which were 58.71%,43.12%,and 60.79%lower than those in 2015.The average emission factors of SO2,NOx,and PM from coal-fired units in China were 0.3,0.48,and 0.06 g·kg^-1,respectively,which were 55.2%,36.84%,and 62.5%lower than those in 2015.The total emissions of SO2,NOx,PM,and PM2.5in thermal power plants were 721.4,1183.8,149.0,and 135.9 kt·a^-1,respectively,down by 41.32%,19.29%,48.12%,and 40.39%from 2015.
