摘　　要：2013年8月和2021年8月对秦皇岛近岸海域24个站位进行了2个航次的大型底栖动物调查,初步研究了调查海域大型底栖动物功能群分布规律以及环境因子对其的影响。结果表明,调查海域大型底栖动物种类组成以环节动物、软体动物和节肢动物为主要类群。大型底栖动物功能群组成以肉食者和碎屑食者为主。2013年大型底栖生物杂食者丰度和生物量低于2021年,其余各功能群均高于2021年。水深、盐度、溶解态无机磷、有机碳和叶绿素a对2013年底栖动物功能群分布的影响较大,水温、水深、盐度、叶绿素a和有机碳是影响2021年底栖动物功能群分布的主要环境因子。In August 2013 and August 2021,two surveys of macrobenthos were conducted at 24 stations in the coastal waters of Qinhuangdao.The distribution of functional groups of macrobenthos and the influence of environmental factors were studied.The results showed that annelida,mollusca and arthropoda were the main groups of macrobenthos in the survey area.Carnivorous and detritivorous were the mainly functional groups of the macrobenthos.The abundance and biomass of macrobenthic Omnivorous in 2013 were lower than 2021,while the other functional groups were higher than 2021.The results showed that temperature,water depth,salinity,chlorophyll a and TOC were the main environmental factors affecting the distribution of functional groups in 2021,whereas depth,salinity,DIP,TOC and chlorophyll a in 2013.
