| 摘 要： | 红树林滨海湿地是在周期性咸水、淡水作用下形成的特殊生态系统,其沉积物中有机质含量丰富,微生物驱动的营养物质循环活跃。由于红树林沉积物中硫酸盐含量高、硫化物种类多,因此红树林是研究硫元素生物地球化学循环过程和机制的理想系统。本文综述了红树林生态系统中主要的硫元素循环过程,重点总结了硫氧化和硫酸盐还原过程及其功能微生物,分析了影响硫氧化和硫酸盐还原的主要环境因素,并对红树林沉积物中微生物驱动硫循环的重点研究方向进行了展望。鉴于微生物驱动的硫循环过程耦合碳、氮和金属元素循环,本文可为深入探究微生物驱动的生物地球化学元素循环耦合机制提供参考。

| Abstract: | Mangrove forest is a special coastal wetland ecosystem and formed by the periodic mixing of freshwater and seawater. The sediment of mangrove wetland is rich in organic matters, accelerating nutrient cycling driven by resident microbes. Due to high concentrations of sulfate and a variety of sulfide in mangrove sediment, mangrove wetland has been considered as an ideal ecosystem to explore sulfur cycling. This review aims to understand the microbially-driven sulfur cycling, especially sulfur oxidation and sulfate reduction processes in the sediment of mangrove wetland. The major environmental factors affecting sulfur oxidation and sulfate reduction are also discussed. Moreover, future research expectations for microbially-driven sulfur cycling in mangrove ecosystem are indicated. |
