摘要
因子分析在研究空气颗粒物来源上得到了广泛的应用。本文应用最大方差旋转因子分析法对中国4城市空气中粗、细颗粒物元素的来源进行了分析。结果指出粗、细颗粒物因子大致可分为土壤源因子和工业污染源因子两大类。粗颗粒物主要来自土壤源,细颗粒物主要来自工业污染源,并指出土壤源因子对粗颗粒物的贡献大于对细颗粒物的贡献。
Factor analysis is widely applied to identifying sources of airborne particulate matter By using factor analysis with varimax rotation, sources of fine and coarse airborne particulate matter of the 4 Chinese cities were studied The study results show that factors of fine or coarse particulate matter can be classified to 2 gross kinds: crust factor and industrial pollution factors Contribution of crust factor of coarse particulate matter is larger than that of fine particulate matter
