摘　　要：通过钻探取样对一个垃圾场底部土层的污染状况进行了现场调查。结果表明,垃圾场下方浅层土壤已受到一定程度的污染,Pb、Cd、Hg、Cr等重金属元素污染较轻,NH3N、TOC值较高。由于该场地下方粘土层的渗透系数很小,污染物的迁移距离在30cm～40cm左右,能较有效地防止垃圾中污染物的快速下渗迁移。Investigation of pollution situation of bottom layer of a landfill by boring sampling was carried out. The result showed that the layer was polluted, with light pollution of heavy metals such as Pb, Cd, Hg, Cr and high values of NH 3 N and TOC. With small infiltration coefficient, migration distance of pollutants was 30～40 cm, which prevented infiltration of pollutants to ground.
