植物修复在治理矿区重金属污染土壤中的应用

Application of phytoremediation to treating contaminated soil by heavy metals in mined land

矿业活动是环境中污染土壤的重金属的主要来源,采用植物修复技术具有物理、化学修复方法所无法比拟的费用低廉、不破坏场地结构、不造成地下水的二次污染等优点。文章从植物稳定、植物提取和植物-微生物以及动物的协同修复等三个方面简要介绍了对矿区污染土壤进行植物修复的研究进展。

Mining activities are major sources of heavy metals that contaminate soil in environment. Compared with physical and chemical remediation, phytoremediation has many merits including lower cost, maintaining the original structure of soil, less possible to cause secondary pollution of groundwater. It has briefly introduced the studying progress of phytoremediation applied to contaminated soil in mined land from three aspects, that are, phytostabilization,phytoextraction, synergistic use of plants and bacteria with animals.
