摘要
于2013年5月,8月和10月份对唐山"三岛"海域12个不同站位小型底栖动物进行调查采样。共鉴定出自由生活海洋线虫、桡足类、多毛类、枝角类、端足类、介形类、涡虫类、轮虫类、双壳类及等足类10个类群。最优势类群是线虫,每个站位所占比例基本大于95%,平均丰度大约735.2ind/10cm2。其他类群各站位所占比例不同,且都较小。结果表明,小型底栖动物各类群所占比例随月份的变化并没明显变化;不同月份,各类群的丰度有所变化,其中5月份丰度较高,10月次之,8月份丰度最低。
A three-cruise investigation on the meiobenthos in the sea of Tangshan three islands was conducted in May ,August and October 2013 .A total of ten meiobenthic groups were identified . Free-living marine nematodes ,copepoda ,polychaeta ,cladocera ,amphipoda ,ostracoda ,turbel‐laria ,rotifera ,bivalvia and isopoda .Nematodes was the most dominant group in abundance ,about 735 .2 ind/10 cm2 ,with a relative dominance of 95% .Other groups of stations with different pro‐portion ,and the smaller .The results showed that ,meiobenthos in each group had no obvious change in the proportion .The abundance of different months ,each group had the change ,which in May higher abundance ,followed in October ,August the lowest abundance .
