摘要
2008年7月、8月和10月及2009年1月和4月,对哈素海浮游动物群落结构进行了调查,共检测出浮游动物4大类,2科28属62种.其中原生动物10属,31种;枝角类2属,6种;桡足类6属,8种.全年优势的浮游动物有无节幼体、象鼻溞、剑水蚤、龟甲轮虫、疣毛轮虫、多肢轮虫、晶囊轮虫、哲水蚤等.大型浮游动物的年均丰度为228.5个/L,年均生物量为1.934mg/L;原生动物的年均丰度和生物量分别为1.68×104个/L和0.049 9mg/L.在各季节中夏季浮游动物量最多,春秋季次之,冬季最少.对哈素海浮游动物优势种类及丰度和生物量指标的分析结果显示,哈素海的水质状况为中富营养水体,并且受到一定程度的污染.
A monitoring of zooplankton and zoobenthos was conducted in Lake Hasuhai in July,August,2008 and January,April,2009.A total of 28 genera and 62 species of zooplankton were detected in Lake Hasuhai.These include 10 genera and 17 species of Protozoa,10 genera and 31 species of Rotifera,2 genera and 6 species of Cladocera,and 6 genera and 8 species of Copepods.Zooplankton of the full-year advantage include Nauplii,Bosmina,Cyclopoida,Keratella,Synchaetidae,Polyarthra,Asplanchnidae and Calanidae.The annual large zooplankton adundance was 228.5/L and biomass was 1.934 mg/L.The average annual abundance and biomass of the protozoan were 1.68×104/L,0.049 9 mg/L in each of seasons the quantity of Zooplankton in summer than spring and autumn,and winter at least.According to zooplankton,abundance and biomass indicators in Lake Hasuhai,the status of water quality is middle nutritional water and a certain degree of pollution.
