摘要
湾塘河是一条流经贵州兴义市城区的城市河流。调查了湾塘河水生植物群落的物种组成、群落类型、分布及物种生物量。结果表明:湾塘河共有水生植物24种,隶属于16科22属,其中挺水植物14种,沉水植物5种,漂浮植物5种。湾塘河水生植物优势种为喜旱莲子草(Alternanthera philoxeroides)、竹叶眼子菜(Potamogeton wrightii)、菹草(Potamogeton crispus)和黑藻(Hydrilla verticillata)。湾塘河水生植物可划分为8个主要群落类型,包括喜旱莲子草群落、竹叶眼子菜群落、菹草群落、黑藻群落、李氏禾(Leersia hexandra)群落、粉绿狐尾藻(Myriophyllum aquaticum)群落、金鱼藻(Ceratophyllum demersum)群落和豆瓣菜(Nasturtium officinale)群落。湾塘河水生植物群落物种多样性低,13个调查样点中有8个样点无水生植物生长或仅有零星生长,主要原因是河流渠道化、污染和外来植物入侵。
Wantang River is an urban river flowing through the urban area of Xingyi City, Guizhou Province. A field survey was conducted on the species composition, community type, distribution, and biomass of aquatic plants in Wantang River.A total of 24 species were observed, including 14 emergent species, 5 submerged species, and 5 floating species, belonging to 16 families and 22 genera. Among them, the dominant species were Alternanthera philoxeroides, Potamogeton wrightii,Potamogeton crispus, Hydrillaand verticillata. The aquatic plants in Wantang River were classified into 8 community types,including communities of A. philoxeroides, P. wrightii, P. crispus, Hydrilla verticillate, Leersia hexandra, Myriophyllum aquaticum, Ceratophyllum demersum and Nasturtium officinale. species diversity was low in Wantang River, and no or very few aquatic plants were found in 8 of 13 sampling sites, mainly due to river channelization, pollution and invasion by alien plants.
