| 摘 要： | 运用GPS定位技术和常规采样方法,于2004年5月和9月对太湖沉水植物与浮叶植物的种类、群落类型、生物量及其水质状况进行了调查。结果表明:沉水植物与浮叶植物是太湖水生植被的主要类型,沉水植物群落类型主要有6个:微齿眼子菜群落;马来眼子菜群落;伊乐藻群落,穗花狐尾藻群落,金鱼藻群落,苦草群落;浮叶植物群落类型主要有3个:莕菜群落,金银莲花群落,菱群落。在春季,沉水植物占绝对优势,在夏秋季,浮叶植物则逐渐发展,尤其以莕菜生长最快。通过对有草区和无草区水质的比较,发现水生植被能显著提高水体的透明度、降低营养盐浓度和叶绿素含量,改善水质。 |

| Abstract: | The community structures of submersed and floating-leaved macrophytes and water environments of Taihu Lake were investigated in 2004. Results showed that two groups of aquatic plants, the submersed macrophytes and floating-leaved macrophytes, dominated the aquatic vegetation of Taihu lake. There were 6 types of submersed macrophyte communities: Ass. Potamogeton mac- ckianus, Ass. Potamogeton malaianus, Ass. Elodea nuttalli, Ass. Myriophyllum spicatum, Ass Ceratophyllum demersum and Ass. Vallisneria natans; and there were 3 of floating-leaved macrophytes communities: Ass. Nymphoides peltatum,A ss Nymphoides in- dica and Ass. Trapa maximowicsil. By comparing the water quality of vegetated and un-vegetated areas, it is found that the aquatic vegetation could significantly improve water quality of lake water. |
