| 摘 要： | １９９６ 年 ６ 月 ２９ 日～１０ 月 ２２ 日对大连市金州区大李家湾贝类养殖筏区及近岸海域进行了调查，对养殖区内、外浮游植物的种类组成和数量分布等生态特征进行了分析。研究结果表明：同一时期养殖区内、外浮游植物的生态特性略有差异，浮游植物的优势种及优势度无明显差别，随季节变化其种类组成有显著改变；筏区内浮游植物的数量略少于筏区外，且高峰期的出现较筏区外滞后 １ 个月；浮游植物平均量的平面分布显示离岸越远其数量逐渐上升。

| Abstract: | The present situation in the areas of rafts of cultivated molluscs in the coastal area of Dalijia Bay, Dalian City was investigated from June to October, 1996, the ecological characteristics such as the specific composition and quantitative distribution were studied and analyzed of the phytoplankton both inside and outside the aquacultured zones (rafts). The results indicate that those ecological characteristics showed slight differences, no obvious differences of dominant species and their abundences were manifested but notable change in specific composition was formed to vary with seasonal variation, the quantity of phytoplankton inside the raft areas was slightly less than that outside and the peak period inside lagged one month behind that outside. The horizontal distribution of the average quantity of the phytoplankton showed a gradual rise in quantity, the farther they were away from the shore. |
