Coastal wetland, affected by the interaction of land and marine ecosystems, is a typical fragile and sensitive zone. Spartina alterniflora is the most successful invasive species in global coastal zone, with important impact on coastal wetland ecosystems. We systematically summarized available literature, and reviewed the effects of S. alterniflora invasion on biogeochemical cycling (soil carbon, nitrogen, phosphorus cycling, and soil heavy metal migration) and biological community (microorganisms, plants, and animals) in coastal wetlands. Then, three perspectives were proposed for the future research: 1) strengthening the mechanism of the impact of S. alterniflora invasion on ecosystem health of coastal wetlands; 2) focusing on the coupling mechanism of the interaction between S. alterniflora community and coastal wetland environment in the context of global change; 3) carrying out long-term positioning monitoring to clarify the responses of coastal wetlands at different stages of S. alterniflora invasion. This review could provide guidance for the ecological utilization and management of S. alterniflora.
受陆地与海洋生态系统相互作用影响，滨海湿地是典型的脆弱敏感区域。互花米草是全球海岸带最成功的入侵物种，对滨海湿地生态系统有重要影响。我们系统总结了现有文献，综述了互花米草入侵对滨海湿地生物地球化学循环（土壤碳、氮、磷循环以及土壤重金属迁移）和生物群落（微生物、植物和动物）的影响。然后，从三个方面对未来研究提出了展望：1）加强互花米草入侵对滨海湿地生态系统健康影响的机制研究；2）聚焦全球变化背景下互花米草群落与滨海湿地环境相互作用的耦合机制；3）开展长期定位监测，阐明滨海湿地在互花米草入侵不同阶段的响应。本综述可为互花米草的生态利用与管理提供指导。
