南极长城湾夏季浮游植物数量与环境的关系

Relationship Between the Phytoplankton Abundance and Environment in the Great Wall Bay, Antarctica

研究了南极长城湾 1 999/2 0 0 0年夏季网采浮游植物的种群动态以及浮游植物数量与营养盐和水温的关系。结果显示 ,浮游植物的细胞数量平均值为 2 87.65× 1 0 4 个 /m3,其中 2月份最高 ,达平均值的 4倍之多。综合 2 0世纪 90年代以来的调查结果 。

The population dynamics of phytoplankon and the relationship between the cell number of phytoplankton and nutrients or water temperature in the Great Wall Bay, Antarctica were studied. It is shown from the study results that the average cell number of net phytoplankton is 287.65×10 4 ind./m 3 in the summer of 1990 2000. There is a cell number peak in February, which is more than four times the average value. It is shown from the summarized investigation results since the 1990s that there is an obvious relationship between the cell number of phytoplankton and water temperature.
