摘要:经调查统计南四湖地区的典型水生维管植物群落共16种:munity Nelumbo nucifera)、芦苇群落(Co. Phragmites australis)、莎草群落(Co. Cyperaceae Cyperus)、喜旱莲子草群落(Co. Alternanthera philoxeroides(Mart.)G)、长苞香蒲群落(Co. Typha angustata)、酸模叶蓼群落( lapathifolium)、水鳖群落(Co. Hydrocharis dubia (Bl.) Backer)、槐叶萍群落(Co. Salvinia natans)、紫萍群落(Co. Spirodela polyrhiza)、浮萍群落(Co. Lemna minor)、莕菜群落(Co. Nymphoides peltatum)、竹叶眼子菜群落(Co. Potamogeton malaianus)、菹草群落(Co. Potamogeton crispus)、穗状狐尾藻群落(Co. Myriophyllum spicatum)、大茨藻群落(Co. Najas marina)、光叶眼子菜群落(Co. Potamogeton lucens),分属挺水植物群落、浮水植物群落、浮叶根生植物群落、沉水植物群落4大类型。群落组成以广布种为主,同时对水生维管植物的价值、利用和保护进行讨论。
