大庆湖泡浮游藻类资源调查及营养状况研究

对大庆市大龙虎泡、红旗水库、黑鱼泡、东湖水库不同水体进行了浮游藻类的采集及分类鉴定;利用浮游藻类的生物量、优势种以及藻类群落组成等指标评价了水质。结果表明:四水体有浮游藻类6门,即硅藻门、绿藻门、蓝藻门、裸藻门、黄藻门、甲藻门;四水体的优势种均为硅藻门、绿藻门、蓝藻门,水体均出现富营养化。根据研究结果,应对四水体采取相应的治理措施以改善水体富营养化状况。

Surveying of floating alage and researching of nutrition state of some lakes in Daqing

The paper has surveyed the collection and taxonomic evalution of the algae water samples in the four lakes,Da longhupao,Hongqi,Hei yupao and Donghu from Daqing city.The paper has also estimated the water quality with living things amounts,predominant kinds and the alga community.6 phylums(Bacillariophyta,Chlorophyta,Cyanophyta,Euglenophyta,Pyrrophyta,Xanthophyta),4 genera have been confirmed.The results had showed that Bacillariophyta,Chlorophyta and Cyanophyta are predominant kinds of the four lakes.All water had been eutrophication.So relevant measure of preventing the lake reservoirs from being eutrophication must be adopted.
