摘要: 对1991年武汉东湖不同湖区浮游动物群落结构的研究表明,Ⅰ、Ⅱ、Ⅲ站浮游动物的数量为122782、70415和18184个·L-1,并随水体富营养化程度增加而增加。生物量分别为8.639、5.872和2.082mg·L-1.大于1mm的甲壳动物个体频度为0.15、0.30、0.41.其体长随鱼产量的增加而缩小。最后,对影响东湖浮游动物群落结构的主要生态因子进行了讨论。

Abstract: The structure of zooplankton community in Donghu Lake of Wuhan was studied in 1991. The number of zooplankton at stations Ⅰ. Ⅱ and Ⅲ is respectively 122782, 70415 and 18184 individuals. L-1, being increased with increasing eutrophication of water body, and the biomass is 8.639, 5.872 and 2.082 mg·L-1 respectively. The frequency of large-sized crustacean (>1mm) is respectively 0.15, 0.30 and 0.41, and its body length is shortened with the increase of fish yield. Ecological factors affecting the structure of zooplankton community are discussed.
