摘　　要：[目的]为优势农产品基地的土壤重金属监测提供依据。[方法]通过对2003年河南省5个优势农产品基地的土壤重金属监测,采用单因子污染指数和综合污染指数的方法,评价了河南省优势农产品基地的土壤重金属污染现状。[结果]结果表明:河南省农产品基地土壤的Cu、Zn、Cd、Cr、Hg、As、Ni、Pb等8种重金属单因子污染指数及综合污染指数均在安全级内,土壤处于清洁水平。[结论]所监测重金属检出率均为100%,除汞、砷轻微超标外,其他几种重金属均未超标。[Objective] The research aimed to provide references for the monitoring of heavy metal pollution of soil in base of dominant agricultural products.[Method] The situation of heavy metal pollution of soil in base of dominant agricultural products of Henan province was evaluated by the means of single factor pollution index,comprehensive pollution index,and the monitoring of heavy metal pollution of soil in five bases of dominant agricultural products.[Result] The single factor pollution index comprehensive pollution index of eight kinds heavy metals Cu,Zn,Cd,Cr,Hg,As,Ni and Pb in bases of dominant agricultural products of Henan province was on the security level and the soil was on the clean level.[Conclusion] The detection rate of monitoring heavy metals was 100%.Except Hg and As exceeded standard slightly,other heavy metals were under national standard.
