| 摘 要： | 根据2008年春(5月)、夏(8月)、秋(11月)、冬(2009年2月)四季东海区桁杆拖虾网调查期间所采集的头足类资料,分析了东海南部海域头足类种类组成及优势种,采用生态多样性指数分析了群落物种多样性,并运用典范对应分析法研究了头足类群落变化与主要环境因子的关系。结果表明:东海南部海域共捕获头足类22种,隶属于3目6科8属,优势种主要有神户乌贼(Sepia kobiensis)、双喙耳乌贼(Sepiola birostrata)、短蛸(Octopus ocellutus)和杜氏枪乌贼(Loligo duvaucelii)等;种类丰富度指数D变化范围为0—1.30,多样性指数H′变化范围为0—1.69,均匀度指数J变化范围为0.02—1.00,t检验表明,各群落多样性指数四季之间的差异均不显著(P0.05);根据典范对应分析认为,底层水温为影响调查海域头足类种类组成的主要环境因子。

| Abstract: | Based on data from surveys with beam shrimp trawl net in 4 seasons of 2008 and 2009 in the East China Sea, using ecological diversity indices and canonical correspondence analysis (CCA), we studied the species and dominant species composition of cephalopod community, analyzed the species diversity, the dynamic change of the community, and its relationships with environmental factors. A total of 22 species were captured, belonging to 3 orders, 6 families and 8 genera, the dominant species were Sepia kobiensis,Sepiola birostrata,Octopus ocellutus, and Loligo duvaucelii. The Margalef species richness index was from 0 to 1.30, Shannon diversity index was from 0 to 1.69, and Pielou evenness
index was from 0.02 to 1.00. No significant differences were observed in the diversity indices in the four seasons. Bottom water temperature was the most important environmental factor affecting the change of the cephalopod species composition in the four seasons. |
