洪湖主要沉水植物群落的定量分析Ⅲ.金鱼藻+菹草+穗花狐尾藻群落
QUANTITATIVE ANALYSIS ON THE MAIN SUBMERGED COMMUNITIES IN HONGHU LAKE.Ⅲ.CERATOPHYLLUM DEMERSUM+POTAMOGETON CRISPUS+MYRIOPHYLLUM SPICATUM COMMUNITY

摘要: 金鱼藻+菹草+穗花狐尾藻群落是洪湖生物量最大的沉水植被类型,在不同的地段存在较大的变化,种类组成复杂,金鱼藻和菹草在不同的季节交替成为群落的优势种。水流是影响不同种群水平分布的主要因素。从水面到水底,植被郁闭度逐步降低。各种对之间不存在显著的联结关系,水流作用及各有关种营养繁殖体的散布方式使得某些种对的生物量分布在一定时期出现最著的相关关系。

Abstract: Ceralophyllum demersum + Potamogeton crispus + Mriophyllum spicatum cotnmunity had the highest seasonal maximum biomass among all the submerged vegetation types in Honghu Lake.This community showed a large difference in different stands.This complicated the species composition, C. demersum and P.crispus became dominant altematively in different seasons.Water flow played a main role in determining the horizontal distribution pattern of popuations.The vegetation cover decreased from water surface to bottom.No significant association was found between different species pairs, but significant correlation was detected between the biomass of some species pairs owing to the effect of water flow and the scatter ways of their vegetative propagation. -
