摘    要:根据2009年8月17日14:00胶州湾21个大面站的同步调查资料,研究了夏季胶州湾浮游植物群落结构特征。共检出浮游植物3门35属65种,平均细胞丰度为77.2cell/m L,硅藻在物种数量和细胞丰度上占绝对优势。主要优势种为中肋骨条藻Skeletonema costatum和大洋角管藻Cerataulina pelagica。夏季胶州湾浮游植物表层细胞丰度的平面分布趋势为北部高于南部,垂直分布趋势为从表层至底层细胞丰度明显降低。表层浮游植物的Shannon-Wiener指数和均匀度指数的分布显示胶州湾西北部和南部浮游植物群落结构更加稳定。与环境因子的相关分析表明浮游植物细胞丰度与盐度呈负相关,与硝酸盐、亚硝酸盐、磷酸盐呈正相关。

关 键 词:浮游植物  胶州湾  夏季  群落结构  同步调查

Abstract:Based on the phytoplankton data of a 21 grid stations synchronous investigation at 14:00 on 17, August 2009 in the Jiaozhou Bay. Three classes including 35 genera and 65 species were commonly found. The average cell abundance was 77.2 cellsind/mLl. The abundance and distribution of diatoms determined the total variation of the phytoplankton abundance. The dominant species were Skeletonema costatum and Cerataulina pelagica. The horizontal distribution of phytoplankton cell abundance was higher in the North of the Bay, lower in the South of the Bay. The vertical distribution of phytoplankton cell abundance was lower significantly from the surface layer to the bottom. The horizontal distribution of phytoplankton Shannon-Wiener index and Pielou index demonstrated northwest and south the Jiaozhou Bay the phytoplanktonic community structure is evener stably. The phytoplankton cell abundance correlated negatively to the salinity, and positively to the nitrate, nitrite and phosphate.
Keywords:phytoplankton  Jiaozhou Bay  summer  community structure  synchronous investigation
