摘　　要：水中藻类生物量的爆发性增长会破坏水体水质,对水生态系统稳定及人类健康造成危害,环境因素和生物因素共同影响着藻类生物量及群落组成。本文从微生物的角度出发,概述了藻际环境中细菌、真菌和古菌的多样性特征,阐述了藻菌之间建立的共生、共栖、竞争及溶藻的生态关系。微生物可以通过一系列营养物质和生长因子的交换促进藻类生长,也可以通过竞争生境中的营养物质或分泌溶藻化合物等方式抑制藻类生长。现阶段关于藻类群落动态变化的研究大多局限于环境因素的驱动作用,而忽视了生物因素的影响。阐明藻菌之间的相互作用有助于深入解析藻类群落时空演替特征,构建藻类群落动态变化的生态驱动机制,从而为藻华的可持续防控提供科学依据。The explosive growth of algal biomass in water can degrade water quality,which poses hazards to the stability of aquatic ecosystems and human health.Both environmental and biological factors have influence on algal biomass and community composition.This review provides an overview of the diversity characteristics of bacteria,fungi and archaea in the phycosphere from a microbiological perspective.It elaborates on the ecological relationships established among algae and microorganisms,including mutualism,commensalism,competition and algicidal interactions.Microorganisms can stimulate the growth of algae through the exchange of a series of nutrients and growth factors.Alternatively,they may engage in nutrient competition within the habitat or release algicidal substances to suppress algal proliferation.Presently,research on the mechanisms governing algal community dynamics tends to concentrate on the impact of environmental factors,which often neglects the role of biological factors.Elucidating the interactions between algae and microorganisms is crucial for a comprehensive analysis of the spatial and temporal characteristics of algal communities.This understanding allows us to construct the ecological driving mechanisms behind algal community dynamics,thereby providing a scientific foundation for the sustainable prevention and control of algal blooms.
