摘　　要：本文运用内梅罗综合污染指数法对某城区采样点提供的重金属元素的浓度数据进行处理,得出其污染程度,运用主成分分析法建立相应的数学模型,对数据进行处理,从而找到主要的污染物,得出Cr、Cd、Pd、Zn元素是造成重金属污染的主要元素,进而找出污染源的所在范围。Abstract： In this paper, concentration data of heavy metal element which is provided by sampling point of a urban district is processed by using Nemerow integrated pollution index method, and its degree of pollution ~s obtained. Corresponding mathematical model was established by principal component analysis method to conduct data processing and then major pollutants were found. Cr, Cd, Pd, Zn are the main elements which cause heavy metal pollution, and then the range of pollution sources was found.
