| 摘 要： | 1999年 7月～ 9月中国首次北极考察期间 ,研究了白令海 2个断面 8个站位海洋蓝细菌数量分布。蓝细菌数量变化在 0～ 7.93× 1 0 3 cell/ml之间 ,水平分布自南向北随纬度的增高而降低 ,在 6 0°N以北的 B1 - 1 2站没有检测到蓝细菌。垂直分布主要分布于 5 0 m以浅 ,最大值出现在B1 - 1站的 2 5 m水深。蓝细菌数量在 5 0 m以下迅速减少 ,到 1 5 0 m水深几乎没有。海水温度和NH+ 4 - N可能是影响蓝细菌数量分布的重要因素

| Abstract: | During the first Chinese scientific expedition to the Arctic in July-September,1999, cyanobacteria in the Bering Sea was measured by epifluorescence microscopy. The result showed cyanobacterial number varied from 0 to 7.93×10 3 cell/ml and decreased along a northerly directed latitudinal gradient in horizontal distribution. We cannot found cyanobacterium at station B1 12 beyond 60°N. Vertical profile of cyanobacteria showed that there was high value in the 25-50m layers and their number decreased rapidly below that, there weren't any cyanobacterium at the 150m layer. Possibly, it is important factors that seawater temperature and NH + 4 N effects the distribution of cyanobacteria in the Bering Sea. |
