摘　　要：微生物固氮是红树林生态系统中氮素循环的一个关键环节,其产生的新氮源对红树林生态系统的氮素营养供给和初级生产力的提高有着重要意义。本文聚焦红树林固氮微生物的研究历史和现状,综述了红树林固氮微生物的群落结构、固氮速率及其测定方法,探讨了固氮微生物在红树林生态修复中的应用及其对红树林生境的指示作用,阐述了固氮微生物在耦合红树林碳、氮、硫元素循环的重要角色,并展望了红树林固氮微生物的研究前景和新视角。Microbial nitrogen fixation is a crucial part of nitrogen cycling in mangrove ecosystems,it plays an essential role in the nitrogen nutrient supply and primary productivity improvement of ecosystem.This paper reviewed the diazotrophic community structure,nitrogen fixation rate,and the main measurement methods of nitrogen fixation in mangrove ecosystems.We also explored the application of nitrogen-fixing microorganisms in mangrove restoration and the ecological indicators of nitrogen-fixing microorganisms for mangrove habitats,emphasized the vital roles of diazotrophs in coupling carbon,nitrogen,and sulfur cycles in mangrove wetlands,and highlighted new perspectives for nitrogen-fixing microorganisms in the mangrove ecosystem.
