摘　　要：为了探究闭库尾矿库无覆土植物修复的可行性,采用野外调查采样和室内分析相结合的方法,对江西省德兴铜矿尾砂库0~60 cm剖面中Cu、Zn、Cd、Pb、Ni等重金属的污染特征及土壤理化性质进行研究,并分析了尾矿库无覆土植物修复的可行性。研究结果表明,4#尾矿库中Cu、Zn、Cd、Pb、Ni的含量分别为743.64~1050.96 mg kg-1、33.27~51.76 mg kg-1、3.96~7.73 mg kg-1、20.17~75.43 mg kg-1、24.62~49.47 mg kg-1。数据显示,Cu、Cd含量都超标,除Cd与Ni外,尾砂土壤其他重金属含量逐渐上升。4#尾矿库的生物修复可以1#尾矿库的修复方案为参考。In order to explore the feasibility of uncovered soil restoration in closed tailings pond,the pollution characteristics and soil physical and chemical properties of heavy metals containing Cu,Zn,Cd,Pb and Ni in the 0~60 cm section of the tailings reservoir of Dexing Copper Mine in Jiangxi Province were studied and the feasibility of uncovered soil restoration in tailings ponds was analyzed by field investigation sampling and indoor analysis.The results showed that the contents of Cu,Zn,Cd,Pb and Ni in the 4#tailings pond are 743.64~1050.96 mg·kg-1,33.27~51.76 mg·kg-1,3.96~7.73 mg·kg-1,20.17~75.43mg·kg-1,24.62~49.47mg·kg-1,respectively.The content of Cu and Cd exceeded the state standard and went down in the vertical direction.Except for Cd and Ni,the content of other heavy metals in the tailings soil gradually increased.The bioremediation of the 4#tailings pond can refer to the soil remediation program of the 1#tailings pond.
