摘　　要：通过北京城区11条河流30个点位沉水植物及水环境因子调查,对沉水物物种分布、生态位特征及与水环境因子相互关系进行了研究,结果表明:北京城区河流均有沉水植物分布,春季优势种为菹草、穗花狐尾藻和篦齿眼子菜,夏季为金鱼藻、狐尾藻、篦齿眼子菜、黑藻、苦草及菹草。水深为影响城区河流沉水植物种类数量的重要因子,菹草为春季沉水植物管理关键物种。研究城区河流沉水植物分布特征及与水环境因子的关系,对北京市河流水生态环境的管理和持续改善具有重要的参考和指导意义。The study of submerged macrophytes and their relationship with environmental factors has important guiding significance for the management and continuous improvement of urban river water ecological environment.Based on the investigation of submerged plants and water environmental factors at 30 points of 11 rivers in Beijing urban area,the distribution of submerged species,ecological niche characteristics and their relationship with water environmental factors were studied.The results showed that:In spring,the dominant species are Potamogeton crispus,Lycophaeton crispus and Crispus crispus.In summer,the dominant species are Potamogeton crispus,Lycophaeton crispus,Blackweed,Potamogeton crispus and Crispus crispus.Statistical analysis indicated that water depth is an important factor affecting the number of submerged plant species in urban rivers,and niche analysis shows that Potamogeton crispus is a key species for management of submerged plant species in spring.
