摘要: 湿地土壤硫(S)的氧化-还原过程是硫循环的重要环节,其对于维持湿地系统的稳定与健康具有重要意义。本文综述了湿地土壤S的氧化-还原过程及影响因素,并分析了其与其他元素耦合机制的研究进展。湿地土壤S氧化-还原过程的影响因素主要涉及生物因子(植物、微生物、底栖动物及人类活动等)和非生物因子(温度、水分和粒度等物理因素及pH、盐度、有机质等化学因素),而其与其他元素的耦合作用主要涉及碳(C)、氮(N)、磷(P)等生源元素以及铁(Fe)、锰(Mn)等金属元素。鉴于当前湿地土壤S氧化-还原过程影响机制揭示不深入、耦合作用研究不均衡及生态效应探讨不充分等问题,未来应重点加强S氧化-还原过程的关键功能微生物研究,强化其与痕量元素迁移转化的耦合机理研究,重视其与其他元素耦合作用的生态效应研究。

Abstract: Sulfur oxidation-reduction process (SORP) in marsh soil is an important link in sulfur cycle, which plays an important role in maintaining the stability and health of marsh. We summarized the SORP in marsh soil and its influencing factors, and analyzed the research progress of its coupling effects with other elements. The influencing factors of SORP in marsh soil mainly involved biotic (plants, microorganisms, zoobenthos, human activities, etc.) and abiotic factors (physical factors such as temperature, moisture and particle size, and chemical factors such as pH, salinity, organic matter, etc.). Related research on the coupling effects of SORP and other elements in marsh soil mainly involved in biogenic elements such as carbon (C), nitrogen (N) and phosphorus (P), and metal elements such as iron (Fe) and manganese (Mn). Currently, the underlying mechanism of SORP was not deeply explored, the research on coupling effects was unbalance, and the ecological effects were insufficient. In the future, key functional microorganisms involved in SORP should be strengthened, the coupling mechanism between SORP and micro-elements should be enhanced, and the ecological effects produced by the coupling effects of SORP with other elements should be emphasized.

Key words: marsh soil, sulfur oxidation-reduction process, influencing factor, coupling effect
