摘要:
为掌握白洋淀浮游植物的群落结构及水质状况, 对白洋淀8个典型采样点进行了采样调查, 共发现浮游植物133种(属), 群落组成以绿藻、硅藻和蓝藻为主;春季以绿藻和硅藻为优势门类, 小球藻、尖尾蓝隐藻、不定微囊藻为优势种(属), 浮游植物的密度在496×104-6256×104cells/L之间, 平均密度为2384×104cells/L;夏季以绿藻和蓝藻为优势门类, 小球藻、粗状细鞘丝藻、肾形藻为优势种(属), 浮游植物的密度在318×104-4630×104cells/L之间, 平均密度为1785×104cells/L, 与2005年以来对白洋淀进行的2次浮游植物生态调查结果比较表明, 浮游植物密度出现显著上升.应用修正卡尔森营养状态指数法和优势种评价法对白洋淀的营养状态进行评价, 结果显示白洋淀多数水体处于富营养状态。

Abstract:
To study the community structure of phytoplankton and assess the water quality in Lake Baiyangdian,an investigation has been conducted at eight typical sampling sites.This investigation showed that among the total 133 species identified,Chloro-phyta,Cyanophyta,and Bacillariophyta were dominant in the phytoplankton community.In spring, Chlorophyta and Bacillariophy-ta were the dominant phylum, and Chlorella sp., Chroomonas acuta.Uterm.and Microcystis incerta Lemm.were the dominant spe-cies.The density of the phytoplankton ranged from 496×104 to 6256×104 cells/L with an average of 2384×104 cells/L.In sum-mer,Chlorophyta and Cyanophyta were the dominant phylum,and Chlorella sp.,Leptolyngbya valderiana Anagn.and Nephrocyti-um agardhianum Nageli.were the dominant species.The density of the phytoplankton ranged from 318×104 to 4630×104 cells/L with an average of 1785×104 cells/L.According to the comparison between this investigation and the previous two ecological inves-tigations since 2005, the abundance of the phytoplankton has increased significantly.The index of Carlson nutritional status and the dominant genus assessment revealed that the majority water was eutrophic in the Lake Baiyangdian.
Key words:  Lake Baiyangdian  phytoplankton  community structure  water quality assessment
