英文摘要	为了解北部湾北部海区浮游动物数量分布规律及优势种组成,2006—2007年对北部湾进行4个航次的综合性调查。根据浮游动物样品分析结果,研究了北部湾北部浮游动物的丰度、生物量和优势种组成,并利用SPEArMAn等级相关法分析丰度与环境因子间的关系。研究结果表明,北部湾北部浮游动物丰度年均值(183.5±142.9)Ind/M3,丰度的季节分布由高到低依次为秋季、夏季、冬季、春季;生物量年均值(139.5±116.8)Mg/M3,由高到低依次为春季、秋季、冬季、夏季特征。平面分布上,春、秋两季丰度分布呈远岸高近岸低的趋势,而夏、冬两季则在近岸海域形成高丰度区。生物量的平面分布趋势与丰度的分布趋势基本一致。丰度变化与环境因子的相关性显著,水深、温度及叶绿素A浓度是影响丰度分布的主要因素。肥胖软箭虫flACCISAgITTA EnflATA、亚强次真哲水蚤SubEuCAlAnuS SubCrASSuS和间型莹虾luCIfEr InTErMEdIuS在北部湾北部的优势地位显著,优势种演替具有明显的季节性。; The distribution of zooplankton abundance and biomass in northern Beibu Gulf were studied based on the samples collected by vertically towing a net(80cm diameter,505μm mesh)including biological,chemical and hydrographic investigation from July 2006to December 2007.This study was important to know the variation of zooplankton abundance,biomass and dominant species.Environmental factors which affected the zooplankton abundance were tested using spearman rank correlation by BIOEVN of PRIMER 5.0.The study showed that both abundance and biomass of zooplankton in northern Beibu Gulf varied clearly with season.The average of abundance was(183.5±142.9)ind/m3,while the average biomass was(139.5±116.8)ind/m3.There was a gradual increase in the abundance from inshore to offshore in spring and autumn,while the abundance was high inshore in summer and winter.The abundance was the highest in autumn,followed by summer,winter and spring.Biomass horizontal distribution was similar with abundance,but varied differently during four seasons,in the order of spring,autumn, winter and summer.The correlation between abundance and environmental factors was significant.Depth,temperature and chlorophyll a were the main factors.Flaccisagitta enflata,Subeucalanus subcrassus and Lucifer intermedius dominated in northern Beibu Gulf especially.The dominant species changed dramatically during four seasons.; 我国近海海洋综合调查与评价专项(908-01-ST09); 海洋公益项目“东南沿海半封闭海湾生态系统对人类活动干扰的响应评价、生态重构技术及示范”(201005012)
