摘　　要：山西省长期以煤、焦、电、化、冶等重工业发展为主,这种发展模式导致了日渐增长的能源消耗和污染物排放,其中重金属排放尤为突出。本研究基于统计年鉴数据和文献资料数据,采用排放因子法估算了1980-2017年间山西钢铁冶炼、建筑材料生产、精炼铜冶炼、燃煤和畜禽粪便排泄等典型途径铅(Pb)的排放清单,分析了其时空分布格局。结果表明,整体上山西钢铁冶炼、建筑材料生产、精炼铜冶炼和燃煤导致的Pb排放量随时间呈增加趋势。山西Pb排放的最主要来源是燃煤,其次为钢铁冶炼。钢铁冶炼导致山西南部地区Pb的排放量较高,建筑材料生产导致Pb的高排放区为吕梁和长治,畜禽粪便导致Pb的高排放区为大同和运城。For a long time,the economic development of Shanxi was dominated by coal-based heavy industry,which has led to increasing energy consumption and pollutant release,especially heavy metals.Based on the statistical and literature data,the emission fluxes of Pb from 1980 to 2017 were estimated by the emission factor method,and then the temporal and spatial distribution patterns were analyzed.The results showed that Pb emissions from iron and steel smelting,building material production,refined copper smelting and coal combustion in Shanxi Province were increasing over time.The coal combustion was the main emission source of Pb in Shanxi Province,followed by iron and steel smelting.The high emission areas of Pb caused by iron and steel smelting were mainly concentrated in southern Shanxi.The higher emission areas caused by building materials production were Luliang and Changzhi,and those caused by livestock manure were Datong and Yuncheng.This study provides a basis for future emission control and risk management of Pb in Shanxi Province.
