土壤重金属污染问题日益严重，对生态环境及人体健康构成了严重威胁。因此，对重金属污染土壤修复方法的原理进行归纳、总结具有重要意义。本文介绍了重金属污染土壤的主要修复技术及有机物料在修复重金属土壤方面的应用，并针对有机物料修复重金属土壤作用机制的研究进展进行了综述，分析了有机物料中的氮、磷、有机质、土壤pH、氧化还原电位对土壤重金属生物有效性的影响，以期为重金属污染土壤修复提供理论参考。“,”The problem of heavy metal contamination of soil is increasingly serious, and it has become a severe threat to ecological environment and human health. It is necessary to summarize the development of remediation of heavy metal contaminated soils. The popular and widely used techniques to remediate heavy metal contaminated soil and the applications were introduced in this article. It focused on the effects of organic materials added into soil on heavy metal phytoavailability, which achieved through changing the concentrations and forms of nitrogen, phosphorus and organic matter, pH, oxidation reduction potential in soil, and the aim is to provide theoretical reference for remediating heavy metal contaminated soils.
