| 摘 要： | 溶解性有机质（DOM）由于含有羟基、羧基等多种活性官能团，成为土壤重金属迁移过程中的重要载体。根据已有的研究成果，在详细介绍了土壤DOM的来源、提取、组成与结构的基础上，分析了土壤DOM与重金属的相互作用机制及其影响因素、DOM对重金属可移动性的影响等相关研究结果，以期为揭示重金属在土壤中的迁移转化规律和重金属污染土壤修复技术提供理论指导。

| Abstract: | Dissolved organic matter （DOM） can be served as the key “carrier” of heavy metals migration because it has many function groups such as hydroxyl, carboxyl etc. Based on current literature, this paper summarized the sources, extraction and composition and organization of DOM in details, analyzed the interaction mechanism between soil DOM and heavy metals and the effect of DOM on the mobility of heavy metals and other related studies in order to reveal the migration and transformation of heavy metals in the soil so that can provide theoretical guidance for heavy metal contaminated soil remediation technologies. |

| Keywords: | dissolved organic matter soil heavy metal mobility and transfer |
