| 摘 要： | 异化铁还原是湿地土壤和沉积物中重要的生物地球化学过程,也是有机质矿化的主要途径之一。湿地干湿交替等过程会使土壤的氧化还原状态发生改变,影响铁元素及与其相关的元素的迁移和转化。总结了湿地土壤和沉积物中异化铁还原过程及其与碳、磷、硫等元素在生物地球化学循环关键过程中的相互作用,阐述了湿地土壤和沉积物中异化铁还原过程对微量金属元素迁移和转化的影响,分析了影响湿地土壤和沉积物异化铁还原过程的主要环境因子。未来相关研究应集中于湿地土壤和沉积物中异化铁还原微生物分析和纯化、不同有机质形式对异化铁还原过程的影响以及异化铁还原对土壤有机质矿化的贡献。

| Abstract: | Dissimilatory iron reduction, an important biogeochemical process in the soils and sediments of the wetlands, is vital for organic matter mineralization. Iron transport and transformation are affected by changes in redox state caused by the alternation of drying and wetting. The relationship between dissimilatory iron reduction and the biogeochemical cycles of carbon was studied, phosphorus and sulfur, as well as the effects on the transport and transformation of the trace elements in the wetlands. The environmental factors which have effects on the dissimilatory iron reduction were also discussed. Future research should focus on separation and purification microorganisms of dissimilatory iron reduction, effects of different forms of organic matter on dissimilatory iron reduction and the contribution of dissimilatory iron reduction on organic matter mineralization in the wetlands. |
