Abstract: The environmental quality of forestry soil polluted by heavy metals in antimony is appraised by measurement six heavy metals element in soil with atomic absorption spectrophotometry in order to afford scientific principle to ecological rehabilitate soil and select afforestation trees and restore vegetation rapidly in Antimony Mine. The soil samples polluted by heavy metals is collected in Antimony Mine of Len-Shuijiang City. The result showed that the content of Sb,As,Pb,Hg,Cd,Zn in soil at three sites there are significant difference. The content of Sb,Hg,Cd,Zn in soil is maximum at Qilipu plot and As is in Changlongjie plot and Pb in Lianmeng polot. The content of Sb,As,Pb,Hg,Cd,Zn reduce with soil depth increasing. The rank of heavy metal pollution is Sb>Cd>Hg>As>Zn>Pb at Lianmeng and Changlongjie plot but Qilipu plot is Sb>Cd>Hg>Zn>As>Pb. There is serious pollution by Sb,As,Cd,Hg and low-grade pollution by Zn,Pb according appraisal standard of nemero index in antimony mine of Len-Shuijiang city. The Sb,Hg in soil transfer is bigger and Zn in soil transfer is medium and As,Pb,Cd in soil transfer is lesser according nemero index and the content of heavy metal distributing character by soil depth.
