摘　　要：通过对惠州西湖五个子湖的浮游动物情况进行调查,共检出浮游动物55种,其中轮虫38种,枝角类10种,桡足类7种,主要优势种为广生多肢轮虫(Polyarthra trigla)、长三肢轮虫(Filinia longiseta)、裂足臂尾轮虫(Brachionus diversicornis)、剪形臂尾轮虫(B.forficula)、角突臂尾轮虫(B.angularis)、萼花臂尾轮虫(B.calyciflorus)、前节晶囊轮虫(Asplanchna priodonta)、刺盖异尾轮虫(T.capucina)、微型裸腹溞(Moina micrura)、温中剑水蚤(Mesocyclops thermocyclopoides)等,多为富营养化指示种,各子湖浮游动物检出丰度处于147.3到726.1ind./L之间,其中轮虫丰度占据优势,浮游动物趋向小型化,结合浮游动物丰度与水质指标进行相关分析结果表明,浮游动物的分布情况与水体水质特征关系密切.Investigation on the zooplankton of Huizhou West Lake which composed of five small connected lakes were carried out for three times from January to September 2005.55 species of zooplankton including 38 species of Rotifers, 10 species of Cladocerans and 7 species of Copepods were found. The dominant species included Polyarthra trigla, Filinia longiseta, Brachionus diversicornis, B. forficula, B. angularis, B. calyciflorus, Asplanchna priodonta, Trichocerca capucina, Moina micrura and Mesocyclops thermocyclopoides which mostly were the indicator species of eutrophication. The abundance of zooplankton were between 147.3and 726.10ind./L and the abundance of Rotifer were on predominance. It showed that the distribution of zooplankton were related closely to the water quality combined with correlative analysis of abundance of zooplankton and chemical and physical index of water.
