| 摘要: |
| 研究水生植物分布与环境因子的关系可为富营养化湖泊的生态修复提供重要科学依据. 通过对长江下游10个不同营养水平湖泊的水生植物群落组成和环境状况进行野外调查,研究了长江下游湖泊主要水生植物分布状况及水环境因子对水生植物分布的影响. 调查发现长江下游10个代表性湖泊主要水生植物共计6科7属11种,主要生活型为沉水植物. 水生植物群落组成与环境因子的冗余分析结果显示,总氮、pH值和水深是显著影响这些不同营养水平湖泊水生植物分布的主导因子. |

| Abstract: |
| The relationship between aquatic plants and environmental factors provides a significant scientific basis for lake restoration.In this study, we investigated community composition of aquatic plants and the relationship between macrophytes and environmental factors, based on the survey about 10 lakes with different trophic levels in the lower reaches of the Yangtze River, from June to July in 2013.Results showed that there were 11 macrophytes species belonging to 6 families, 7 genera.Redundancy analysis indicated that total nitrogen, pH and depth are the key factors for the distribution of aquatic plants in lakes with different trophic levels in the lower reaches of the Yangtze River. |
