矿区重金属污染土壤的植物修复

PTYTOREMEDIATION OF SOILS CONTAMINATED BY HEAVY METALS IN MINED LAND

近年来,重金属污染环境的问题引起人们的广泛关注,其中矿业活动是环境中重金属的最主要来源。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。可起到美化环境的作用,因此易于被社会所接受,是一项很有发展前途的修复技术。本文从植物稳定、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矿区污染土壤植物修复的研究进展。

In the present years, the environmental problems that are caused by the heavy metals are becoming more and more serious. The main sources of heavy metal pollution is the mining activities. Compared to physical and chemical remediation, phytoremediation has many merits, such as lower cost, maintain the original structure of soil, less possible to cause secondary pollution. Besides, it will not only beautify our environment, but also can be easily accepted by the public. So it＇s very bright and useful to research the phytoremediation. This article summarizes the phytoremediation in mined land in the following three parts： phytostabilization, phytoextraction, synergistic use of plants and bacteria.
