摘要：

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。

Abstract:

In this paper, the current situation of heavy metal pollution in soil was discussed in such aspects of major form of heavy metal in soil, assessment index of pollution level, circulation mechanism, mutual effect of ions and remediation methods in order to study the research development of different remediation methods and the future works of heavy metal pollution. The future of research status was prospected in an effort to provide reference for other researchers. Results showed that basic research of heavy metal pollution in soil needed to be further studied, especially the circulation mechanism. Plant and microorganism remediation methods were main parts of heavy metal remediation, together with other remediation methods.
