根据8种元素之间的相关系数初步判断元素之间的关联关系,再通过主成分分析法分析造成各功能区污染的主要重金属,进而分析了各重金属污染的主要原因。结果显示,该城区生活区主要受污染的重金属是Pb、 Hg和As,主要来源于生活垃圾、汽车尾气和工业污染；工业区的污染重金属较多,主要有Hg、 Cu、 Cr、 Pb、 Cd、 Zn,主要来源为工业废水、汽车尾气和轮胎磨损；而在该城区的山区几乎未受到任何重金属污染,山区上的重金属含量主要来源于岩石；交通区主要受到Cu、 Zn、 Pb三种重金属的污染,主要来源于汽车尾气排放、轮胎磨损和经过大气传播的工业废气的污染；公园绿地区主要受到Pb、 Cu、 Zn三种重金属的污染,主要来源于汽车尾气排放、轮胎磨损和经过大气传播的工业废气的污染。

Judging the relationship between elements according to the correlation between the eight elements preliminary, and analyzing each functional area pollution caused by heavy metals through the analysis of the principal component , the main causes of heavy metal pollution were analyzed. Results showed that in the urban living area the main heavy metals pollution was Pb, Hg, and As, the main pollution came from domestic waste, automobile exhaust and industrial pollution. Industrial pollution of heavy metal was exhaust and industrial pollution. Industrial pollution of heavy metal were mainly Hg, Cu, Cr, Pb, Cd, Zn, the main source was industrial wastewater, automobile exhaust and tire wear. The pollution in the mountain was mainly Cu, Zn and Pb, the heavy metal contents mainly came from rock on the mountain. The pollution in transport area was mainly Cu, Zn and Pb, this heavy metal pollution mainly came from vehicle emissions, tire wear and after atmospheric propagation of industrial waste gas pollution. The pollution in park green areas was mainly Pb, Cu and Zn, this heavy metal pollution mainly came from vehicle emissions, tire wear and industrial waste gas pollution after atmospheric propagation.
