摘要/Abstract

摘要： 为研判浙江庆元铅锌矿矿区重金属污染状况，并遴选土壤重金属污染修复的优势植物，在对矿区土壤和植物不同部位重金属含量测定的基础上，进行了各重金属元素污染及各元素间的相关性分析，并对重金属的潜在生态危害程度进行评价。结果表明，土壤受Pb、Cr的污染较重，Pb、Cd为极强的生态风险，Cu为轻微—中等风险，Zn为轻微风险，5个评价区域的综合潜在生态风险均为极强；马尾松对重金属有较强的耐性，可作为先锋树种之一。

关键词: 铅锌矿区, 重金属污染, 生态风险, 植物修复

Abstract: In order to study the heavy metal pollution situation in Qingyuan Pb-Zn mining area,Zhejiang Province,and select the dominant plants for remediation of heavy metal pollution in the soil,based on the determination of heavy metal content in different parts of the soil and plants in the mine,the pollution of heavy metal elements and the correlation among the elements were analyzed,and the potential ecological harm degree of heavy metals was evaluated.The results show that the soil is heavily polluted by Pb and Cr,Pb and Cd are extremely strong ecologi-cal risks,Cu is slight to medium risks,Zn is slight risks,and the comprehensive potential ecological risks of the five evaluation areas are extremely strong;Pinus massoniana has a strong tolerance to heavy metals,which can be used as one of the pioneer tree species .

Key words: Pb-Zn mining area, Heavy metal pollution, Ecological risk, Phytoremediation
