摘要
论文基于当前湖泊水—沉积物系统中Fe、Mn的循环迁移、赋存形态以及与周围其他物质(微量重金属元素、营养盐、有机质)之间相互作用的研究,通过收集资料和归纳总结已有研究数据发现,湖泊铁一锰循环不仅受氧化还原边界层化学界面的控制,而且受沉积物一水地质界面的制约;溶解态Mn^(2+)和Fe^(2+)在水体的垂直变化是相似的,受溶解氧和H2S浓度的影响;沉积物一水界面上Fe^(2+)循环受硫酸盐还原作用抑制,而Mn^(2+)循环则激烈进行。研究和认识湖泊水—沉积物系统铁锰循环的发生机制,对淡水湖泊的水质保护和污染治理具有重要的理论和现实意义。
In this paper, based on the study of the cyclic migration,the occurrence of Fe and Mn,and interaction between Fe, Mn and other substances（trace heavy metals, nutrients, organic matter）, and through the data collection and summary of existing research data we found that Fe and Mn cyclic in lake is not only controlled by boundary layer chemical redox interface, but also restricted by the sediment-water interface of geology. The vertical variation of dissolved Mn^（2＋）and Fe^（2＋）in water is similar, and they are affected by dissolved oxygen and concentration of H2 S.The Fe^（2＋）cycle in sediment-water interface was inhibited by sulfate reduction, while the Mn^（2＋）cycle was intense. It is of great theoretical and practical significance to study and understand the mechanism Fe-Mn cycling in lake water sediment system.
