摘要
系统梳理了水绵的危害,水绵在春末夏初开始大量生长,易于形成藻垫漂浮在水面上产生腥臭味,破坏生态系统平衡,危害水源水质安全,影响水域生态景观.分析表明水绵的生长受水动力条件、光照强度、营养物质和水温等条件的影响.重点研究了水绵的原位控制方法,水绵防控是一个系统工程可结合物理法、化学法应急清除水绵,长期控制水绵则需要选择生物法.同时,水绵在恶劣环境条件下具有较好的繁殖,可利用水绵其固碳和吸附等能力进行生物修复,应用于水生态环境中.对水绵在水环境中的水体营养、生态环境和生物监测的评价等方面的前景进行了展望.
Abstract
This paper systematically analyzes the hazards posed by Spirogyra.The algae starts to grow in late spring and early summer,forming algal mats on the water surface,emitting fishy odors,disrupting the ecosystem balance,jeopardizing water quality,and impacting the water's ecological landscape.Analysis reveals that Spirogyra's growth is influenced by hydrodynamic conditions,light intensity,nutrients,water temperature,and other factors.The study focuses on in-situ control methods for Spirogyra,emphasizing its systematic prevention and control.While emergency removal can involve physical and chemical methods,long-term Spirogyra control requires adopting biological approaches.Moreover,Spirogyra exhibits robust reproduction under harsh environmental conditions,making it suitable for bioremediation due to its carbon sequestration and adsorption capacity,applicable to water ecosystems.The paper discusses the prospects of Spirogyra in the water environment concerning water body nutrients,the ecological environment,and bio-monitoring evaluation.
