摘要
重金属污染土壤的修复问题一直是全世界面临的一项难题。与其他修复方法相比,植物修复由于对土壤扰动小、费用低、操作简单等优点,将成为未来重金属污染土壤治理的主要方向。综述了土壤重金属的来源及植物对重金属污染土壤的修复机理,重点对植物修复技术目前存在的问题及今后为提高植物修复技术所能采取的改进措施进行了探讨。
Heavy metal pollution in soil is a pressing problem to be solved in the world. Compared with other methods of the remediation, the phytoremediation is a progressive one to deal with the heavy metal con- taminated soil due to the less interference to the soil, the lower cost and the easier operation. In the paper, we summarized the sources of the heavy metal in the soil, the remediation mechanism of phytoremediation with the emphasis of its limits and the methods to increase the effect. Hopefully, it could provide the evidences with the further research in this field.
