| Abstract: | 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
