摘　　要：对贵阳市开阳县8个乡镇茶园土壤中铅、镉、铬、铜、汞、砷这6种重金属元素含量进行了检测,以无公害茶叶产地环境条件中土壤环境要求为背景值作为标准对其单项和综合污染指数进行分析评价。结果表明:调查区域内土壤重金属含量差异较大,且部分受到了不同程度的污染。在重金属污染因子中,Hg是主要污染因子,其次是Cd。Tea plantation soil samples from 8 villages and towns in Kaiyang county of Guiyang city were tested for content of six heavy metals,Pb, Cd, Cr, Cu, Hg and As. Combined with pollution-free standard of soil in tea garden, heavy metal pollution was evaluated by using single factor pollution index and Nemerow pollution index. The results show that the contents of heavy metals in the soil vary markedly and some of the areas are polluted. The major pollution factor of the soil is Hg, followed by Cd.
