中文摘要：
利用Primer数据统计软件对2012年11月、2013年2月、2013年5月和2013年8月东山湾海域浮游动物进行数据分析,结果表明调查海域浮游动物明显分为了湾外群落、漳江群落、河口群落和湾内群落,不同浮游动物群落在种类丰度组成、种类季节变化和多样性季节变化上存在一定差异性。漳江群落受冲淡水影响最大,在种类组成上主要为异体住囊虫、红住囊虫、小拟哲水蚤和右突歪水蚤;河口群落处于半咸水区域,以太平洋纺锤水蚤为主;湾内群落以太平洋纺锤水蚤、针刺拟哲水蚤和中华哲水蚤为主;湾外群落的肥胖箭虫、亚强次真哲水蚤和针刺拟哲水蚤是构成丰度结构最重要的种类。纵观4个季节浮游动物不同群落优势种的变化,发现在2012年11月和2013年2月4个群落的优势种差异并不明显,但在2013年5月和2013年8月4个群落优势种明显不同。
英文摘要：
Data in November 2012, February 2013, May 2013 and August 2013 of Dongshan Bay zooplankton were analyzed by primer statistical software.Results indicate that zooplankton were clearly divided into the outer bay community, Zhangjiang community, estuarine community and inner bay communities.Different zooplankton communities varied in abundance composition, seasonal variations of species and seasonal variations diversity.Zhangjiang communities were most affected by the diluted water, species are mainly Oikopleura dioica,Oikopleura rufescens,Paracalanus parvus and Tortanus dextrilobatus;Estuarine communities in the brackish region, Acartia pacifica is the main species with little seasonal change in number and diversity;The inner bay community was dominated by Acartia pacifica,Paracalanus aculeatus and Calanus sinicus;Sagitta enflata,Subeucalanus subcrassus and Paracalanus aculeatus constitute the most important species abundance in bay communities.Throughout the four seasons＇ changes of dominant zooplankton species in different communities, the difference of dominant species in four communities in November 2012 and February 2013 is not obvious.In May 2013 and August 2013,in four communities, the dominant species were significantly different.
