中文摘要：

利用统计方法对青岛地区土壤重金属元素地球化学基线进行了研究,给出了重金属元素Cd、Hg、Cu、Pb、Cr、Zn和Ni的地球化学基线分别为251.0449ng/g、53.3151ng/g、32.7476ug/g、50.2807ug/g、42.7389ug/g、120.8170ug/g和16.3610ug/g.应用地球化学基线计算重金属元素地累积指数大小,从而进行污染等级评价.结果表明：青岛地区土壤中重金属元素污染程度大小排列为Ni〈Cd〈Pb〈Cr〈Cu〈Zn〈Hg,重污染与极重污染主要集中于工业生产多、交通运输量大及人类活动频繁的区域.

英文摘要：

This paper provides a statistical method for the geochemical baselines of heavy metal elements in Qingdao soils,and the geochemical baselines of seven heavy metal elements such as Cd,Hg,Cu,Pb,Cr,Zn and Ni were calculated to be 251.0449ng/g,53.3151ng/g,32.7476ug/g,50.2807ug/g,42.7389ug/g,120.8170ug/g and 16.3610ug/g,respectively.Geoaccumulation indexes were calculated according to the baselines,and level assessment of pollution was acquired.The level sequence was obtained as Ni〈Cd〈Pb〈Cr〈Cu〈Zn〈Hg,and heavy or extremely heavy pollution were mainly in the areas which suffer from a lot of industrial product,transportation and human activities.
