| 摘 要： | 本研究基于2018年在线监测数据等，分析中国水泥行业主要工序（窑头和窑尾）排口烟气浓度情况，自下而上建立了2018年中国高时空分辨率水泥行业大气污染物排放清单（high resolution cement emission inventory for China，HCEC）.结果表明，2018年中国水泥行业的PM、SO2和NOx排放量分别为72893、92568和878394 t.从时间维度：2018年中国水泥行业主要工序烟气排口月均浓度逐步降低，蓝天保卫战成效显著.从区域维度：2018年京津冀及周边地区、长三角地区和汾渭平原，水泥窑年均排放浓度整体低于全国平均水平，但各城市排放浓度存在差异.2018年安徽省水泥行业排放量最大，北京市和天津市水泥行业的单位面积污染排放强度最大.

| Abstract: | This study analyzed the concentrations of exhaust gas in the process (kiln head and kiln tail) of China''s cement industry, based on data from continuous emission monitoring systems network in 2018. The cement emission inventory for China with high resolution (high resolution cement emission inventory for China, HCEC), using the bottom-up approach, was established. The results indicated that during 2018, the total emissions of PM, SO2, and NOx were 72893, 92568, and 878394 t, respectively. In terms of temporal evolution, the exhaust concentration of flue gas in the main process gradually decreased, with obvious emission reduction from the Blue Sky Protection Campaign. Regionally, the exhaust concentrations of flue gas of the kiln head and kiln tail in Beijing-Tianjin-Hebei and surrounding areas, and the Yangtze River Delta and Fenwei Plain, showed a considerable decline, with a high to average level in China. The flu concentrations of each city differed; the cement industry in Anhui Province generated the largest emission in the country, while Beijing and Tianjin showed the highest emission intensity per unit area. |
