- 摘要：通过发放调查表、现场咨询等形式，获得苏州市2012年工业企业基本信息，参照国内外已有研究成果，确定排放因子，并根据实际情况对钢铁行业进行了系数修订，得到苏州市工业源大气细颗粒物排放清单.结果表明：苏州地区工业源PM2.5排放总量约为6.57×104 t，工艺过程源和固定燃烧源分别占94%和6%；张家港地区贡献率最大，为51%，其次为常熟13.8%；姑苏区贡献率最小，为0.13%；苏州市平均排放强度为10.42 t·km-2，张家港排放强度最大，达到了43.57 t·km-2，其次为新区12.38 t·km-2；钢铁与炼焦、火电、水泥行业是PM2.5的主要贡献者，分别为50%、17%和14%；空间分布显示苏州北部相对细颗粒污染较大，重点企业多集中在张家港、常熟地区，东部污染较少.
- Abstract：Based on the collected activity data and emission factors, a 2012-based atmospheric fine particulate matter emission inventory from industrial sources was developed for Suzhou City. The results showed that the annual PM2.5 emission from industrial sources in Suzhou was about 6.75×104 t. Emission from production process and fixed combustion sources accounted for 94% and 6%, respectively. Industrial sources from Zhangjiagang district contributed to the largest fraction (51%), followed by Changshu (13.8%). The average emission intensity was 10.42 t·km-2 in Suzhou City. The emission intensity of Zhangjiagang was the highest (43.57 t·km-2), followed by Gaoxin district (12.38 t·km-2). Steel and coking, thermal power and cement industry were the main contributors of PM2.5 emissions, with contribution rates of 50%,17% and 14%, respectively. The spatial distribution characteristics revealed that PM2.5 emissions were relatively higher in northern areas of Suzhou city. The key enterprises were mainly concentrated in Zhangjiagang and Changshu area.
