| 摘 要： | 系统地对呼伦湖浮游植物现状进行了调查和监测,调查结果显示,呼伦湖共有浮游植物142种属,隶属8门、22目、40科,其中绿藻门69种,硅藻门29种,蓝藻门27种,裸藻门5种,甲藻门3种,隐藻门2种,黄藻门4种,金藻门3种。以绿藻、蓝藻和硅藻为优势种属。浮游植物平均生物量为6.995mg.L-1。在此基础上,分别以浮游植物种类生态学指标和PCQ模型对呼伦湖水质进行评价,并验证了PCQ模型用于富营化评价的可行性,结果表明呼伦湖处于富营养状态。

| Abstract: | A survey concerning phytoplankton and nutritional levels in Hulun Lake were conducted.The results showed that there were a total of 142 genera phytoplankton,belonged to 8 phylum,22 orders and 40 families in the Lake.Chlorphyta accounted for the most genera and bacillariophyta took the next,with 69 and 29 genera respectively.Cyanophyta represented 27 genera,while euglenophyta,pyrrophyta,cryptophyta,xanthophyta and chrysophyta had 5,3,2,4 and 3 genera respectively.Chlorphyta,cyanophyta and bacillariophyta were the dominant phytoplankton.The average biomass of phytoplankton was found to be 6.995 mg·L-1.In addition,the nutritional level of Hulun Lake was in eutrophication according to the result of PCQ model and ecological indicators for phytoplankton species. |
