用投影寻踪回归进行大气颗粒物的污染源解析

 应用投影寻踪回归技术（PPR）对大气颗粒物的污染源成分谱和大气采集样本中的元素测试数据进行分析，得到大气颗粒物的污染源的权重贡献率的一种原解析新方法该方法应用于上海大气颗粒物的污染源的解析,结果表明，影响上海市大气颗粒物的主要污染源是建筑尘、土壤尘、燃煤尘和冶金尘它们的平均贡献率之和十占全部尘源的85%以上

Sources apportionment of atmospheric particulates by projection pursuit regression

Based on the analysis of the data of element contents in atmospheric samples and the source profiles ofatmospheric pal'ticulates.a new method of sources apportionment of atmospheric particulates denoted with weightedcontribution rate was suggested using projection regression technique.The results of this method applied inShanghai Urban showed that the sum of the average contribution rates from the sources of building consmiction, soil,coal burning and metallurgical industry (which are the main pollution sources of atTnospheric pAnculates in ShanghaiUrban) surpassed 85%.
