| 摘 要： | 研究了2010年冬季胶州湾23个大面站浮游植物的群落结构特征。共检出浮游植物5门44属69种，平均细胞丰度为222.8 cells/mL，其中硅藻在物种数量和细胞丰度上占绝对优势。主要优势种为柔弱几内亚藻Guinardia delicatula、扭链角毛藻Chaetoceros tortissimus、诺氏海链藻Thalassiosira nordenski?ldii和尖刺伪菱形藻Pseudo-nitzschia pungens。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，垂直分布则为各水层之间细胞丰度相差不大。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南至湾口海域浮游植物群落更加均匀稳定。与环境因子的相关分析表明浮游植物细胞丰度与铵盐、硝酸盐、亚硝酸盐、硅酸盐呈显著的正相关。

| Abstract: | Features of phytoplankton community were studied based on the phytoplankton data of a 23 grid stations investigation in winner 2010 in the Jiaozhou Bay. Five classes including 44 genera and 69 species were commonly found. The average cell abundance was 222.8 ind/ml. The abundance and distribution of diatoms determined the total variation of the phytoplankton abundance. The dominant species were Guinardia delicatula, Chaetoceros tortissimus, Thalassiosira nordenski?ldii and Pseudo-nitzschia pungens. 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 no significant difference from the surface layer to the bottom. The horizontal distribution of phytoplankton Shannon-Wiener index and Pielou index demonstrated southeast to the mouth of Jiaozhou Bay the phytoplanktonic community structure is comparatively even and stable. The phytoplankton cell abundance correlated positively to the ammonia, nitrate, nitrite and silicate. |
