摘　　要：利用SPSS软件中的因子分析和聚类分析方法找出工业源影响环境质量的废水、废气两个因子,结合全市工业源污染排放特征,对重庆市工业源区域环境污染分布特征进行初步分析。结果表明:万州区因辖区内工业源废水中总氮和氨氮排放量较高,受工业废水污染影响较大;綦江区、长寿区和江津区因辖区内工业源废气中二氧化硫、氮氧化物排放量较高,受工业废气污染影响较大;涪陵区、永川区、合川区因辖区内工业源废水中化学需氧量、氨氮和废气中二氧化硫、氮氧化物排放量都相对较高,受工业源废水、废气的复合型污染;其他32个区县工业源废水、废气特征污染物排放量相对较少,受工业源的影响不显著。In order to analyze the characteristics of industrial pollution in Chongqing,two factors of industrial sources affecting environmental quality including waste water and exhaust gas were obtained by using factor analysis and cluster analysis in SPSS.The results showed that Wanzhou district was mainly affected by industrial wastewater pollution because the total nitrogen and ammonia nitrogen emissions were relatively higher.Qijiang district,Changshou district and Jiangjin district were mainly affected by industrial source exhaust gas because the sulfur dioxide and nitrogen oxide emissions were higher.Fuling district,Yongchuan district and Hechuan district were mainly affected by industrial source waste water and exhaust gas because the total nitrogen and ammonia nitrogen emissions and sulfur dioxide and nitrogen were higher.The emission of industrial waste water and exhaust gas is relatively small in other 32 districts,which were not significantly affected by industrial sources.
