| 摘 要： | 从 1997年 4月到 1998年 3月之间 ,应用定性观察和定量分析的方法对广州市的城市湖泊——越秀湖进行了浮游纤毛虫群落的种类组成、群落的生物多样性、丰度、生物量、优势种的种群季节变化等群落结构参数进行了研究 .共发现了 76种浮游纤毛虫 ;最大丰度为 6 9.1×10 3 ind.· L-1;最大生物量为 7.16 mg· L-1;群落中的优势种为大弹跳虫 (H alteria grandinella)、尾毛虫 (Urotricha spp.)、尾侠盗虫 (Strobilidium caudatum)、小侠盗虫 (Strobilidium humile)和膜袋虫 (Cyclidium spp.) ;群落的生物多样性指数在 2 .4到 3.0之间 .分析了这个湖泊浮游纤毛虫群落结构参数的季节变化 .通过与文献报道的比较、分析 ,从纤毛虫的优势种、总丰度和生物量确定了该城市湖泊的富营养状况为重度富营养化 .

| Abstract: | From Apr 1997 to Mar 1998, using the qualitative and quantitative methode, a study on the ecology of planktonic ciliates in an urban lake in Guangzhou-Yuexiu Lakt, was carried out In the study, some param eters of the ciliate community lice species compositibn abundance biomass and biodiversityind ices were analyzed 76 ciliate species were recorded The results showed that themajy dominant species were Halteria grandinella Strobilndium caudatmn, Strobilidium humile Cyclidium spp and U rotricha spp., the maximum total abundance was 6 91×104 ind °L-1 in May, meanwhile, the maxmum totalbiom ass was 7.16mg°L-1 in June The population dynamics and succession of dominant species were studied aswell Based upon the structuralparam eters of the ciliate community, a comparison with literatures the water quality of the lake can be considered beiig hypereu trophic. |
