摘　　要：描述无锡2001—2020年工业废水、废气与烟(粉)尘排放量时空演变后,运用LMDI模型对其影响因素展开分析。研究表明:样本期内,工业废水与烟(粉)尘排放量总体下降,废气排放量数倍增加;当前,市区与江阴污染排放量较多,尤其是废水与废气;经济规模导致工业污染排放量增加、产业结构使其减少、技术水平作用方向不同,且3个因素对不同污染物影响效应存在显著差异;从地区角度看,市区与江阴贡献较大,4个时段不同污染排放量增减方向与驱动主因(因素贡献与地区贡献)也不同。After describing the temporal and spatial evolution of industrial wastewater,waste gas and smoke(powder)dust emissions in Wuxi from 2001 to 2020,the influencing factors are analyzed by LMDI model.The results show that during the sample period,the emission of industrial wastewater and smoke(powder)dust decreases as a whole,and the emission of waste gas has increased several times;At present,there are relatively more pollution emissions in urban areas and Jiangyin,especially wastewater and waste gas.Economic scale leads to the increase of industrial pollution emissions,the reduction of industrial structure,and the action direction of technical level is different,and there are obvious differences in the action degree of the three factors on different kinds of pollution.In terms of regions,the urban area and Jiangyin contribute greatly to the change of industrial pollution emissions.The increase and decrease direction and driving factors(factor contribution and regional contribution)of pollution emissions of different varieties are also different in the four periods.
