| 摘要: |
| 本文研究了2009年春季胶州湾23个大面站浮游植物的群落结构特征。共检出浮游植物3门47属74种, 平均细胞丰度为827.77 cell/mL, 其中硅藻在物种数量和细胞丰度上占绝对优势。主要优势种为丹麦细柱藻Leptocylindrus danicus和中肋骨条藻Skeletonema costatum。调查期内浮游植物表层细胞丰度的平面分布趋势为北部高于南部, 湾内高于湾口, 浮游植物的垂直分布则为各水层之间细胞丰度相差不大, 没有明显的差异。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东北部浮游植物群落较西南部更加均匀稳定。与环境因子的相关分析表明浮游植物细胞丰度与温度呈正相关。 |

| Abstract: |
| We studied the phytoplankton community in spring 2009 in the Jiaozhou Bay based on phytoplankton data from 23 grid stations. Three classes including 47 genera and 74 species were determined. The average cell abundance was 827.77 cell/mL. The diatoms abundance and the distribution controlled the total variation of phytoplankton abundance. The dominant species were Leptocylindrus danicus and Skeletonema costatum. The horizontal distribution of phytoplankton cell abundance was higher in the northern part of the bay, and lower in the southern part. The vertical distribution of phytoplankton cell abundance had no significant difference between the surface and the bottom. The horizontal distribution of phytoplankton Shannon-Wiener index and Pielou index demonstrated that the phytoplanktonic community structure was relatively evener and more stable in the northeastern part of the bay than those of the southwestern. The phytoplankton cell abundance correlated positively to the temperature. |
