| 摘 要： | 根据2006-2007年“国家908”专项台湾海峡4个航次调查，分析该海域浮游甲藻的种类组成、群落结构和时空分布特征。共鉴定甲藻18属131种，其中高温高盐种为主体，占总种数的72．52％，其次为广温广盐种，占总种数的25．19％，近岸种仪占2．29％。夏季甲藻的种类最丰富，而春季甲藻的丰度最高。平均丰度为404．96×10^2cells／m3，其平面分布呈现从近岸向外海、从北向南递增的趋势。与1984-1985年的调查结果相比较，甲藻丰度的平面分布格局和季节变化趋势没有明显变化，但丰度增加3．01倍。从季节变化看，冷季甲藻丰度增加较为显著；从平面分布看，台湾海峡北部增加较多。此外，该海域甲藻群落结构也发生变化，种类多样性指数和均匀度上升，其丰度占浮游植物总丰度的比例由0．55％上升到1．02％。

| Abstract: | Based on 4 cruise surveys from July 2006 to October 2007 in the Taiwan Strait, the species composition, community structure and spatio-temporal distribution of dinoflagellate were studied. A total of 131 dinoflagellates belonging to 18 genera were identified. The population was dominated by hyperthermal and hyperhaline species accounting for 72.52% of the total species. Eurythermal and euryhaline species were the second most common one accounting for 25.19% of the total species. It was only 2.29% for neritic species. The maximum species number occurred in summer, while the maximum cell density appeared in spring. The average dinoflagellate cell density was 404.96x104 cells/m3. It showed that the dinof]agellate cell density increased from the nearshore waters to the open sea and from the north to the south. Compared with the results during 1984-1985, the horizontal distribution pattern and seaeonal variation of the dinofiagellate have not changed significantly, but the dinoflagellate cell density increased by 3.01 times. Further analysis of the dinoflagellate abundance variations both in the spatial and temporal aspects, indicated that the abundance of dinoflagellate increased more significantly in cold seasons, and there was a larger increase in the north of the Taiwan Strait. Besides, the dinoflagellate community structure changed notably. It showed that the diversity and evenness index were relatively high, and the proportion of dinoflageliate cell density to the total phytoplankton increased. |
