摘  要：
根据2015年冬(3月)、春(5月)、夏(8月)、秋(11月)季4个航次对海州湾海域的浮游动物进行的调查采样,分析了浮游动物的种类组成、丰度、生物量、优势种、生物多样性以及不同季节的变化特点。结果表明:本次调查共鉴定到浮游动物47种(不含浮游幼体17种),种类数夏季(31种)>秋季(29种)>春季(27种)>冬季(17种);平均丰度为117.31ind·m~(-3),春季(256.24 ind·m~(-3))>秋季(89.81 ind·m~(-3))>冬季(74.93 ind·m~(-3))>夏季(48.26 ind·m~(-3));平均生物量为249 mg·m~(-3),秋季(369 mg·m~(-3))>冬季(274 mg·m~(-3))>春季(214 mg·m~(-3))>夏季(140 mg·m~(-3));主要优势种为中华哲水蚤(Calanus sinicus)、真刺唇角水蚤(Labidocera euchaeta)和强壮箭虫(Sagitta crassa);生物多样性指数(H)、均匀度(J)和丰富度(d)都是夏季最高,分别为2.81、0.73、3.21;中华哲水蚤对海州湾海域浮游动物丰度贡献最大;本海域浮游动物具有明显的季节性和南北过渡性;温度在大尺度范围内影响浮游动物时空分布,下行效应在小尺度范围内直接控制浮游动物的空间分布格局。

摘  要：
Based on the samples collected from the four cruises carried out in winter(March),spring(May),summer(August) and autumn(November) of 2015,the species composition,abundance,biomass,dominant species,biodiversity and distribution of zooplankton along the coast of Haizhou Bay were analyzed.The results showed that totaling 47 species(excluding 17 plankton larvae) were inspected;the ranking of number of species in each season was summer(31 species)>autumn(29 species)>spring(27 species)>winter(17 species).The annual average abundance was 117.31 ind·m~(-3),and the ranking of seasonal value of abundance was spring(256.24 ind·m~(-3))>autumn(89.81 ind·m~(-3))>winter(74.93 ind·m~(-3))>summer(48.26 ind·m~(-3)).The annual average biomass was 249 mg·m~(-3),and the ranking of seasonal value of biomass was autumn(369 mg · m~(-3))>winter(274 mg · m~(-3))>spring(214mg·m~(-3))>summer(140 mg·m~(-3)).The dominant species in the area were Calanus sinicus,Labidocera euchaeta and Sagitta crassa.The highest diversity index(H),evenness(J) and richness(d) all appeared in summer,and Calanus sinicus made the largest contribution to the zooplankton abundance in the area.Zooplankton had obvious seasonality and transition from south to north.Temperature was primarily responsible for the spatial and temporal distribution of zooplankton on large scale,while the top-down effect accounted for the distribution in small scale.
