摘    要:根据2008年9月2009年2月在胶州湾中部海域进行的逐月定点底拖网调查数据,分析了该海域秋、冬季鱼类群落结构特征和多样性变化。结果表明,该海域秋、冬季共捕获鱼类50种,隶属8目,28科,42属;秋、冬季鱼类的相对资源量存在明显的月间变化,平均网获质量为每网865.29~5173.71g,平均网获尾数为每网111~717ind。秋、冬季优势种组成有明显的季节更替现象,主要由暖温性和暖水性的季节洄游种变为地域性的暖温性和冷温性种,仅六丝钝尾虎鱼(Amblychaeturichthys hexanema)为秋、冬季的共有优势种。种类丰富度指数(R)变化范围为2.08~3.25,多样性指数(H′)变化范围为1.50~2.44,均匀度指数J′为0.52~0.76;秋、冬两季间鱼类群落物种多样性指数差异均不显著(P0.05)。聚类分析和多维标度法(MDS)分析表明,6个月的样本可分为秋季组(9~11月)和冬季组(12~2月)2个组分;单因子相似性分析(ANOSIM)表明,秋、冬季组分间鱼类群落结构无显著性差异(P0.05)。

关 键 词:胶州湾  鱼类群落结构  物种多样性

Abstract:Jiaozhou Bay which locates in the south of Shandong peninsula is an inland semi-enclosed natural bay extending from the Yellow Sea.With the rapid development of cities and the excessive exploitation and utilization of coasts of Jiaozhou Bay recent years,eutrophication in the coastal waters has frequently happened which threatened the circular utilization and sustainable development of coastal ecological environment and biological resources.There was a declining tendency in fishery resources in Jiaozhou Bay ...
Keywords:Jiaozhou Bay  fish community structure  species diversity
