| 摘 要： | 目的]调查研究昆明城市河流盘龙江水生植被演变状况及其原因。方法]开展盘龙江2006～2007及2011年水生植被跟踪调查研究,盘龙江水质监测及相关资料收集工作。结果]耐污性较强的蓖齿眼子菜、黑藻等水生植物是盘龙江的优势物种。2006～2007年共采集到33种水生植物,2011年采集到35种水生植物。盘龙江综合整治后水质明显改善,2011年较2006～2007年水生植被呈现喜清水的水生植物种类有所增加、沉水植被分布区域增大、群落结构更丰富稳定、外来入侵种分布明显缩小等特点。结论]随着盘龙江综合整治的大力推进,盘龙江水质及水生植被得到明显改善。

| Abstract: | Objective] To study the evolution of aquatic plants in Panlong River and its causes.Method] The aquatic plants in Panlong River were investigated in 2006-2007 and 2011,and the water quality data was collected.Result] The dominant species in Panlong River are pollution-resist species,such as Potamogeton pectinatus and Hydrilla verticillata.Thirty-three aquatic plants were collected from 2006 to 2007 and thirty-five aquatic plants were collected in 2011.Water quality in Panlong urban river was improved significantly from 2006 to 2011,the species of aquatic plants fond of clean water increased,distribution area of submerged vegetation was extended,distribution area of alien invasive species was narrowed and community structure became more stable.Conclusion] After the prevention of pollution in recent years,water eco-system of Panlong River has been restored initially. |
