| 中文摘要 |
| 建材行业是典型的资源和能源消耗型产业，也是大气污染的主要排放源之一.中国作为全球最大的建材产品生产国和消费国，目前针对建材行业排放特征的研究总体较少，数据来源较为单一.以河南省建材行业为研究对象，首次将应急减排清单应用到排放清单构建中，通过对应急减排清单、排污许可和环境统计等多源数据的融合研究，完善和细化了建材行业活动水平数据，建立了更为精准的河南省建材行业排放清单.结果表明，2020年河南省建材行业的SO2、NOx、一次PM2.5和PM10的排放量分别为21788、51427、10107和14471 t.其中，水泥和砖瓦是河南省建材行业大气污染物排放占比最高的2个行业，合计超过50%，水泥行业NOx排放问题较为突出，砖瓦行业整体治理水平比较落后.豫中和豫北是河南省建材行业排放贡献最高的地区，合计超过全省的60%.建议加快推进水泥行业超低排放改造，针对砖瓦等行业完善地方排放标准，持续提升建材行业大气污染治理水平. |
| 英文摘要 |
| The building materials industry is a typical resource and energy-consuming industry, as well as one of the major sources of air pollution. As the world's largest producer and consumer of building material products, China thus far has insufficient research on the emissions of the building materials industry, and the data sources are short of multiplicity. In this study, the building materials industry in Henan Province was chosen,and the control measures inventory for pollution emergency response (CMIPER) was applied to the development of the emission inventory for the first time. Through the integration of multi-source data such as CMIPER, a pollution discharge permit, and environmental statistics, the activity data of the building materials industry was refined, and a more accurate emission inventory of the building materials industry in Henan Province was established. The results showed that the SO2, NOx, primary PM2.5, and PM10 emissions of the building materials industry in Henan Province in 2020 were 21788, 51427, 10107, and 14471 t, respectively. Cement and bricks and tiles were the two categories with the highest contribution of emissions from the building materials industry in Henan Province, accounting for more than 50% in total. TheNOx emission of the cement industry was a key issue, and the overall emission control level of the brick and tile industry was relatively unadvanced. The central and northern parts of Henan Province contributed the most emissions in the building materials industry, accounting for more than 60%. It is recommended to further implement ultra-low emission retrofit in the cement industry, and for other industries such as the bricks and tiles, the improvement of local emission standards is encouraged to persistently promote the emission control of the building materials industry. |
