摘　　要：随着水体环境质量的逐渐被修复,将水生植物用于生态修复中已经成为水环境净化的主要手段之一。其中修复沉水植物群落是水生态保护工程的内容之一。以铜龙河综合治理项目为载体,以五种土著沉水植物苦草、黑藻、穗状狐尾藻、菹草、篦齿眼子菜为主要研究对象,经人工配置呈3种群落搭配,研究不同群落对水质指标及氮、磷等营养物质去除的效果。结果表明:3种群落搭配对水质净化的效果不同,主栽种为菹草的配置类型处理效果最佳。研究结果可以指导水生态修复工程中沉水植物群落选种搭配,有助于提升沉水植物群落对水质净化的效果,对水生态的修复具有重要参考意义。In suit ecological remediation has been recognized as a vital method for improving water environment,along with water environment quality gradually recovering.In particular,submerged macrophyte community restoration act an important role in ecological protection of water environment.In this paper,the restoration of submerged plant communities was examined as an important approach for water environmental governance,particularly within the context of the Tonglong river comprehensive governance project.Different combinations of five indigenous submerged plant species,namely Vallisneria spiralis L.,Hydrilla verticillata Royle,Myriophyllum spicatum L.,Potamogeton crispus L.,and Potamogeton pectinatus L.,were investigated for their effects on water quality indicators and the removal of nutrients such as nitrogen and phosphorus.The research results can guide the species selection and collocation of submerged plant communities in water ecological restoration projects,help to improve the effect of submerged plant communities on water purification,and have important reference significance for water ecological restoration.
