利用超积累植物修复铜绿山古铜矿重金属污染土壤的潜力分析

On the Potential of Hyperaccumulator in Repairing the Heavy Metal Polluted Soil in Daye Tonglvshan Cooper Mine

植物修复是以植物忍耐和超量积累某种或某些污染物的理论为基础,利用植物及其共存微生物体系清除环境中污染物的环境污染治理技术。介绍了超积累植物的特性及其作用机理,在分析湖北铜绿山古铜矿土壤重金属含量、植被类型及优势植物对重金属的积累特性基础上,综合评价超积累植物修复铜绿山矿区重金属污染土壤的潜力。

Phytoremediation is a technique of environmental pollution management by using hyperaccumulator plants and coexisted microorganism to remove the pollutants. This article aimed to analyze the characteristics of bioaccumulation and tolerance mechanism of hyperaceumulator and comprehensively evaluate its potential in repairing the heavy metal polluted soil in Tonglvshan Cooper Mine on the basis of analyzing the heavy metal content of the soil, vegetation types and the accumulating characteristics of advantageous plants.
