摘　　要：检测分析了越西县农产品产地土样18个,土壤质量按照国家有关标准进行综合评价,结果表明:土壤重金属单因子污染指数最小的是Pb,其次为As、Hg、Cu和Cr,最大的为Cd,污染指数达到1.675,有15个土样存在Cd污染;Cd、Hg、As、Pb、Cr和Cu的土壤综合污染指数分别为1.675、0.423、0.413、0.226、0.760和0.604,说明该基地土壤Cd存在轻度污染,Cr存在潜在危害。Eighteen soil samples of the agricultural produced in Yuexi County was analyzed,and the soil quality was conducted a comprehensive evaluation.Soil quality was evaluated in accordance with the relevant national standards.The smallest single factor pollution index of soil heavy metal is Pb,followed by As,Hg,Cu and Cr;the largest pollution index is Cd reached 1.675,and there are 15 soil samples existed in Cd pollution.The soil integrated pollution index of Cd,Hg,As,Pb and Cr and Cu is 1.675,0.423,0.413,0.226,0.760 and 0.604,respectively,indicating that the production base of soil is in the light pollution of Cd,and there is a potential hazard of Cr.
