Coastal wetlands (CW) are the junction of the terrestrial and marine ecosystems and have special ecological compositions and functions, which are important for maintaining biogeochemical cycles. Microorganisms inhabiting in sediments play key roles in the material cycle of CW. Due to the variable environment of CW and the fact that most CW are affected by human activities and climate change, CW are severely degraded. In-depth understanding of the community structure, function, and environmental potential of microorganisms in CW sediments is essential for wetland restoration and function enhancement. Therefore, this paper summarizes microbial community structure and its influencing factors, discusses the change patterns of microbial functional genes, reveals the potential environmental functions of microorganisms, and further proposes future prospects about CW studies. These results provide some important references for promoting the application of microorganisms in material cycling and pollution remediation of CW.
海岸湿地（CW）是陆地和海洋生态系统的交汇处，具有特殊的生态组成和功能，对维持生物地球化学循环至关重要。栖息于沉积物中的微生物在海岸湿地的物质循环中发挥着关键作用。由于海岸湿地环境多变，且大多数海岸湿地受到人类活动和气候变化的影响，海岸湿地正严重退化。深入了解海岸湿地沉积物中微生物的群落结构、功能及环境潜力对于湿地恢复和功能增强至关重要。因此，本文总结了微生物群落结构及其影响因素，讨论了微生物功能基因的变化模式，揭示了微生物的潜在环境功能，并进一步提出了海岸湿地研究的未来展望。这些结果为推动微生物在海岸湿地物质循环和污染修复中的应用提供了一些重要参考。
