摘要
本文讨论了南极海冰(包括沿岸海域的固定冰和外海域的广阔浮冰)形成的物理过程及冰藻的聚集机制,海冰的基本理化特性及微小生物群落的生态学特征。并阐述了海冰微小生物群对维持极地海洋初级生产,促进生物能量传递等所起的重要作用,从而证明南极海冰带是整个极区海洋生态系统中不可缺少的关键环节。
In this paper it is discussed that of the development and physical properties of Antarctic sea ice (including fast ice and pack ice),and the mechanism for algal assemblege in sea ice. Also it is explained that of the ecological charecteristies of microbiota in sea ice and its important role to maintain the marine primary production and improve the transportation of biotic energy. Therefore the authors suggest that the sea ice zone could be a crucial link in Antarctic marine ecosystem.
