| 摘 要： | 1 引 言城市湖泊由于人类活动的强烈影响 ,大多已处于富营养化状态 ,严重降低了湖泊价值 .作为水生态系统中重要的组成部分 ,底栖动物是某些经济鱼类的饵料生物 ,而且其群落结构与水体环境有着密切的关系 ,水质的好坏直接或间接影响到底栖动物的生长、繁殖和种类分布 .国外多年前就已经使用底栖大型无脊椎动物 ,尤其是摇蚊科 (Ｃｈｉｒｏｎｏｍｉｄａｅ)幼虫和寡毛类的分布格局来作为湖泊营养状态和污染程度的指标1,3 ,5] .近年来 ,我国在这方面也进行了一些研究2 ,4 ,6,7] .研究底栖动物群落结构特征及其与环境因子的关系 ,可为湖泊…

| Abstract: | There are only 21 species of benthonic animals in the Nanhu Lake, Changchun. The dominant species in the benthos community are obvious, and the individual quantity of Limnodrilus hoffmeisteri, Branchiura sowerbyi, and Tendipus plumosus accounts for 87% of the total individual quantity of all benthonic animals. It indicates that the water in the Nanhu Lake is suffering serious organic pollution, and belongs to an eutrophic lake. The peak values of benthos biomass and energy are found in July(48.23 g WW.m-2 and 241.16 kJ.m-2 respectively), while the maximum individual quantity is appeared in May(401 ind.m-2). The distribution of Oligochaeta and aquatic insects has a significant positive correlation to organic content in the sediment(alpha < 0.05). The community structure of benthonic animals reflects adequately the feature of the Nanhu Lake as an eutrophic lake in temperate zone. |
