| 摘 要： | 微齿眼子菜群落是洪湖面积最大的沉水植物群落，以１９９２－１９９３年的调查资料为基础，选择两个不同的群落地段对该群落进行了定量分析。群落种类组成简单，定量生长型谱可以反映不同群落地段的变化状态。群落组成种分布均一，水平结构简单。群落的垂直结构主要决定于微齿眼于菜生物量的空间分布，可区分为水柱下层的垫状层和水中的稀疏层，各组成种之间不存在联结关系，分布各自相互独立，而相关分析则发现在一定时期，某些种对之间生物量的空间分布存在一定的重叠。

| Abstract: | Potamogeton maackianus Community was a main submerged communitytype which covered the largest area in Honghu Lake. Based on the survey during1992-1993 at two different stands, this paper analyzed quantitatively the communitystructue. The species compositions were simple, and the quantitative growth typespectra could specify the difference of the two stands. All the composition speciesdistributed evenly. The biomass distribution in water column of Potamogetonmaackianus mainly determined the vertical structure of the community. Associationanalyses indicated that all the species distributed independently, but the correlationanalyses revealed that at some seasons, the distribution of some species pairesoverlapped to certain. |
