摘要
对梁子湖水 -陆交错区中植物群落的组成、结构、生长型和生物量进行了测定 ,结果表明交错区内共分布有 9种植物群落 :1)微齿眼子菜 (Potamogeton maackianus)群落 ;2 )狐尾藻 (Myriophyllum spicatum) +苦草 (Vallis-neria natans) +金鱼藻 (Ceratophyllum demersum)群落 ;3)微齿眼子菜 +金鱼藻群落 ;4)金鱼藻 +狐尾藻 +微齿眼子菜群落 ;5 )金鱼藻 +狐尾藻 +荇菜 (Nymphyoides peltatum)群落 ;6 )水蓼 (Polygonum hydropiper) +菱 (Trapabispinosa) +菰 (Zizania latifolia)群落 ;7)菹草 (Potamogeton crispus)群落 ;8)菰 +荇菜 +水蓼群落 ;9)湿生植物(Helophyte)群落。主要植物群落生物量为 :狐尾藻 +苦草 +金鱼藻群落 2 414g· m- 2 ,金鱼藻 +狐尾藻 +微齿眼子菜群落 4379g· m- 2 ,微齿眼子菜 +金鱼藻群落 1486 g· m- 2 ,微齿眼子菜群落 2 80 5 g· m- 2。交错区内主要植物群落生物量的季节变化与群落内优势种的生长方式、人为活动的干忧以及个体生态特征密切相关。
The feature and the structure of plant communities were measured and the life form spectrum and the growth form spectrum of the communities in the water-land ecotone of Liangzi Lake were analyzed. Nine types of communities were described: 1) Ass. Potamogeton maackianus; 2) Ass. Myriophyllum spicatum, Vallisneria natans, Ceratophyllum demersum; 3) Ass. P. maackianus, C. demersum, M. spicatum; 4) Ass. C. demersum, P. maackianus; 5) Ass. C.demersum, M. spicatum, Nymphyoides peltatum; 6) Ass. Polygonum hydropiper, Trapa bispinosa, Zizania latifolia ; 7) Ass. Potamogeton crispus ; 8) Ass. Z. latifolia, N. peltatum, P. hydropiper; 9) Ass. Helophyte .The biomass of four dominant submerged communities was analyzed as follow: Ass. M. spicatum, V. natans, C. demersum; Ass. P. maackianus, C. demersum, M. spicatum; Ass. C. demersum, P. maackianus; Ass. P. maackianus was 2414 g·m -2, 4379 g·m -2,1486 g·m -2, 2805 g·m -2 respectively. The seasonal changes in the biomass of the main communities were the results for their growth patterns and human interference, and different species showed its own feature. The distribution of species was independent from each other and the distribution patterns of almost all species were contagious.
