摘　　要：近年来微塑料在海洋中的不断积累,引发了人们对海洋生态系统功能及生态多样性的关注,其中包括蓝藻在微塑料上定植所产生的影响。在微塑料上定植,会对蓝藻的生长和形态、光合作用和脂肪酸产生不同的影响。而蓝藻的定植则会改变微塑料的物化特性,同时还表现为降解微塑料或延缓光老化过程。通过定植作用,蓝藻与微塑料产生相互作用,影响海洋生态系统初级生产力的同时,通过食物链的逐级传递,对整个海洋生态系统产生影响。本研究对蓝藻定植于微塑料在海洋生态系统中的研究现状进行概述,强调未来需要进一步开展的研究工作,以更好地理解蓝藻的定植对彼此及整个生态系统的潜在影响,这将为制定有效的保护措施和管理策略提供重要的科学依据。In recent years,the continuous accumulation of microplastics in the ocean has raised concerns regarding the functionality and biodiversity of marine ecosystems,including the impact of cyanobacterial colonization on microplastics.The colonization of microplastics by cyanobacteria has diverse effects on cyanobacterial growth,morphology,photosynthesis,and fatty acid production.Concurrently,cyanobacterial colonization alters the physicochemical properties of microplastics,exhibiting characteristics such as degradation or the retardation of photoaging processes.The interaction between cyanobacteria and microplastics,facilitated through colonization,not only influences the primary productivity of marine ecosystems but also extends its impact throughout the entire marine ecosystem via successive trophic levels in the food chain.This review provides an overview of the current research status on cyanobacterial colonization of microplastics in marine ecosystems.It emphasizes the need for further research to better comprehend the potential impacts of cyanobacterial colonization on both the organisms involved and the entire ecosystem.Such understanding is crucial for the development of effective conservation measures and management strategies,providing a scientific foundation for future initiatives.
