摘　　要：针对寻找重金属污染源的位置问题,利用标准差体现数据离散程度的性质,对重金属元素的分布情况进行分析,并运用主成分分析法,建立了一个确定污染源的数学模型.通过对收集数据的处理,可以方便而快捷地找出重金属污染源.A directed search for heavy metal pollution source location problem,using standard deviation of discrete degree of the data,on the distribution of heavy metals were analyzed,and using the method of principal component analysis,establishes a mathematical model to determine the pollution source,based on the collected data processing, can find the pollution source of heavy metals conveniently and quickly.

关 键 词：重金属污染 标准差 主成分分析法 污染源
