土壤重金属污染及修复方法研究进展

为了解土壤重金属污染现状、各种修复方法的研究动态以及未来重金属的研究方向，笔者综述了土壤重金属的主要形态、污染程度评价指标、循环机制、离子间相互效应、修复方法等，并对今后的研究方向进行展望，为其他研究者提供参考。结果表明：关于土壤重金属的基础性研究还有待于进一步地深入和发展，特别是重金属的循环机制；重金属修复以植物和微生物修复为主体，其他修复方法并用将是趋势。

Research Progress of Heavy Metal Contamination in Soil and Remediation Method

The current status of heavy metal pollution in soil was discussed from some aspects such as major form of heavy metal in soil, assessment index of pollution level, circulation mechanism, mutual effect of ions and remediation methods in order to understand the research situation of different remediation methods and the future works of heavy metal pollution. The future research directions of heavy metal pollution in soil were given so as to provide reference for other researchers. It is pointed out that the basic research of heavy metal pollution in soil needed to be further conducted, especially the circulation mechanism. Plant and microorganism remediation methods were main parts of heavy metal remediation, and other remediation methods were together involved.
