摘要
Abstract
Using the principal component analysis to parse the source of eight heavy metals (Cd,Pb,Cu,Zn,Hg,As,Cr,Ni) in surface sediments of volcano dammed lake in Wudalianchi The results showed that:The accumulation contribution rate of the first three principal component reached 84268%,largely reflected the basic source of heavy metals in surface sediments of volcano dammed lake in Wudalianchi The first principal component was "natural source",the second principal component was "agriculture non-point source",the third principal component was the "human activities point source" The first principal component had the decisive significance Must attention the pollution problems of As and Hg.关键词
