| 摘 要： | 束丝藻（Aphanizomenon）是一种丝状固氮蓝藻，具有入侵性且易暴发有害水华。近年来，在全球气候变化推动下束丝藻的扩张已然成为一种世界范围的现象，其广泛分布在温带、热带水体中，因其能合成藻毒素和异味物质而严重影响水生态系统功能，威胁饮用水安全和人类健康。束丝藻耐低温、喜低光，在偏碱性、低氮高磷水体中增殖较快，并凭其固氮、储磷以及释放藻毒素、形成群体胶鞘等独特生态策略使其在种间竞争以及群落结构演替中获得较大竞争优势，成为优势种群。鉴于束丝藻的危害性和扩张性，本文从束丝藻的生理生态特性、分布特征、竞争优势及其关键驱动因子等研究前沿进行了综述，并对相关研究领域进行展望，为进一步研究束丝藻种群竞争优势形成机制，有效防控束丝藻水华提供科学依据。

| Abstract: | Aphanizomenon is a filamentous and nitrogen-fixing cyanobacteria, which is invasive and prone to harmful algal blooms. In recent years, the expansion of Aphanizomenon has become a worldwide phenomenon driven by global climate change. Aphanizomenon is widely distributed in temperate zone and tropical water bodies, and its ability to synthesize algal toxins and odors seriously affects the functioning of aquatic escosystems, posing a threat to drinking water safety and human health. Aphanizomenon is low temperature resistant, preferring low light, proliferating rapidly in alkaline, low nitrogen and high phosphorus water bodies. With its unique ecological strategies of Aphanizomenon such as nitrogen fixation, phosphorus storage, release of algal toxins, and formation of group sheaths makes it gain a greater competitive advantage in interspecific competition and community structure succession, becoming an advantageous population. In view of the harmfulness and expansion of Aphanizomenon, this paper reviewed the research frontiers of Aphanizomenon, including its physiological and ecological characteristics, distribution characteristics, competitive advantages and key driving factors, and also provide prospects for relevant research fields, providing scientific basis for further research on the formation mechanism of competitive advantages of Aphanizomenon, and effective prevent and control of Aphanizomenon bloom. |
