| 摘 要： | 长江口特殊的生态环境使得浮游动物的种类组成、密度和时空分布等生态特征有别于其它水体。2005年秋季(丰水期)和2006年春季(枯水期)对长江口南北支浮游动物进行了2个航次的调查,沿南北支由西向东设立3个采样断面共20个采样点。共采集到浮游动物227种,其中轮虫65种,原生动物107种,枝角类15种,桡足类40种。优势种包括龟甲轮虫(Keratella)、刺簇多肢轮虫(Polyarthra trigla)、萼花臂尾轮虫(Brachionus calyciflorus)、砂壳虫(Difflugia)、表壳虫(Arcella)、砂壳纤毛虫(Tintinnid)、中华哲水蚤(Calanus sinicus)、汤匙华哲水蚤(Sinocalanus dorrii)、广布中剑水蚤(Mesocyclops leuckarti)、象鼻溞(Bosmina)等。文章对南北两支浮游动物的种类组成和结构进行了比较,南支浮游动物的种类、数量及生物多样都高于北支,南北两支的浮游动物群落相似度很低。南北两支水域环境的不同造成其浮游动物群落结构的较大差异,文章分析了环境因子与浮游动物群落结构的相关性,其中水温是重要的影响因素,水温的季节性决定...

| Abstract: | The special ecological environment at Yangtze River estuary makes zooplankton there different from other water in ecological characteristics such as species composition,density and time-space distribution etc.Two times' investigations were taken in spring(drought season) and autumn(raining season) from2005 to 2006 along the north and south branches,where three cross-section and 20 survey points were set.A total of 227 zooplankton species were identified,with 65 species of rotifers,107species of protozoas,15... |
