摘要
水绵(Spirogyra)藻华是城市景观水体中突出的环境问题,为探究长效生态型综合防治措施,对黄山徽艺小镇非遗创意园景观水体水绵藻华进行了调查分析和综合治理。结果表明,在城市静态浅水型景观水体中,水绵具有休眠—萌发—扩增—暴发的生长周期和双峰暴发模式,水绵藻华的主要成因为水体富营养化、流速缓慢、水体透明度高及水绵具有低温优势等,据此提出了集清除水绵藻团的短期治理目标、减少适宜水绵生长生境的长期治理目标、日常管理养护于一体的综合防治方案。治理后,水绵藻华得到有效控制,水体水质得到提升,生态系统生物多样性增加。研究结果可为城市静态浅水型景观水体水绵综合防治和管理维护提供科学依据。
Spirogyra blooms are a prominent environmental issue in urban landscape water bodies.To explore long-term,eco-friendly integrated control strategies,this paper investigates and manages Spirogyra blooms in the landscape water bodies of the Huangshan Huiyi Town Intangible Cultural Heritage Creative Park.The results indicate that in urban static shallow water bodies,Spirogyra follows a growth cycle characterized by dormancy-germination-expansion-outbreak,often exhibiting a bimodal bloom pattern.The main causes of Spirogyra blooms include water eutrophication,slow flow velocity,high water transparency,and its growth advantage under low temperatures.Based on these findings,a comprehensive strategy was proposed,combining short-term objectives(removal of Spirogyra mats)with long-term goals(reducing favorable habitats),integrated with routine maintenance and management practices.Post-treatment results showed effective control of the blooms,improved water quality,and increased ecological biodiversity.The study provides a scientific basis for the integrated control and maintenance of Spirogyra in urban static shallow landscape water bodies.
