摘
要: 以东北老工业基地北部城市群为例,对其重点区域及周边的不同土地利用类型中 Hg,Pb,Cr,Zn4 种元
素进行测定分析,利用单因子污染评价和多因子污染评价方法进行评价。结果表明,4 种元素在不同利用类型
土壤中,汞和铅在土壤中的迁移能力较弱,且汞元素在土壤中积累程度不高,只是在个别区域其含量有所波动;
铅在农田和工业用地土壤中都有一定的积累,但向其他利用类型土壤的迁移效果不明显; 铬在个别区域的旱
田,蔬菜地中的积累略高,并迁移威胁到了其周围的林地土壤; 锌在某些地区的工业用地,旱田,蔬菜地的污染
程度相比其他几种元素污染更为严重。

Abstract: The contents of heavy metals( Hg,Pb,Cr,Zn) In dIfferent land - use types soIl form the focus and the surroundIng
area of ChIna's Northeastern Old IndustrIal Base were analyzed. Moreover,evaluate them wIth SIngle factor evaluatIon and multI -
factor evaluatIon methds. The results showed that the four kInds of elements In dIfferent land - use types soIl,the movement abIlIty
of Hg and Pb Is weak and the accumulatIve extent of Hg Is not hIgh In soIl,the content may fluctuate only In a few regIon; Pb has
a certaIn accumulatIon In arId areas,vegetables areas and IndustrIal areas,but the movement effect Is not obvIo
