中文摘要：

1982～2008年对中国南极长城站和中山站地区主要湖泊、溪流、雪地等淡水藻类进行了调查研究.结果表明,淡水藻类优势种类为：双尖菱板藻（Hantzschiaa mphioxys）,端泥生藻（Luticola mutica）,拟钝泥生藻（Lutiola muticopsis）,细小隐球藻（Aphanocapsa elachista）,极小色球藻（Chroococcus minimus）,寒冷席藻（Phormidium frigidum）,赖氏鞘氏藻（Lyngbya lagerheimii）,拉氏黏球藻（Gloecapsa ralfsiana）,易脆席藻（Phormidium fragile）,雪衣藻（Chlamydomo nasnivalis）,南极侧果藻（Pleurococcus antarcticus）,南极螺翼藻（Scotiella antarctica）和细长聚球藻（Synechococcus elongates）.回归分析显示了微、小型藻类细胞丰度与水温呈显著的正相关,而与磷酸盐和硝酸盐呈显著负相关.南极气候尤其是水温的变化,引起湖泊藻类丰度与种群结构发生改变.

英文摘要：

In 1982-2008, field investigations were carried out which mainly included lakes and snows around the two stations.Abundant species had been identified;they were Hantzschia amphioxys, Luticola mutica, Lutiola muticopsis, Aphanocapsa elachista, Chroococcus minimus, Phormidium frigidum, Lyngbya lagerheimii, Gloecapsa ralfsiana, Phormidium fragile, Chlamydomonas nivalis, Pleurococcus antarcticus, Synechococcus elongates and Scotiella antarctica.Climate change will affect species abundance and population structure.The regression analysis showed that the cell abundance of nano-and microalgae was in a remarkable positive correlation with the water temperature, but in a remarkable negative correlation with phosphate and nitrate.The change of Antarctic climate especially water temperature resulted in the variation of algae abundance and population structure in lakes.
