摘　　要：个旧锡矿废弃区杜仲地重金属污染严重,Cd为24.229mg/kg,Zn为3648.383mg/kg,Pb为2072.276mg/kg,As为61.290mg/kg,Cu为133.509mg/kg;所在区杜仲重金属污染也较严重,各部分干重Cd、Zn、Pb、As、Cu平均含量分别为11.007、1528.873、76.706、38.425、8.184mg/kg,其中杜仲皮污染最为严重。杜仲重金属污染与杜仲地土壤重金属含量存在一定相关性,且较稳定。The heavy metals pollution was serious in Eucommia soil of Gejiu tin mine wasteland,and Cd was 24.229 mg/kg,Zn was 3 648.383 mg/kg,Pb was 2 072.276 mg/kg,As was 61.290 mg/kg,Cu was 133.509 mg/kg.Heavy metal pollution of Eucommia was also serious,dry weight of Cd,Zn,Pb,As,Cu average levels were 11.007,1 528.873,76.706,38.425,8.184 mg/kg.The Eucommia bark pollution was most serious.The heavy metals pollution of Eucommia and heavy metals in wasteland has a certain stability correlation.
