摘　　要：浮游植物是水质生物学重要的评价指标,又是水域自然鱼产力的主要限制因子。2006年5月至2008年9月对大庆黑鱼泡水源浮游植物进行了调查研究,结果表明,该水域浮游植物种类由2005年以前36属种增加到现在的52属种,分属于6门,32科,52属,第一优势种由硅藻门变为绿藻门,水质有由富营养化向重富营养化发展的趋势,初步判定水源受到了一定程度的污染。单从浮游植物方面评价,水域自然鱼产力较好。Phytoplankton is an important assessment index of water quality biology, and mainly limited factor of natural fish productivity. From May 2006 to September 2008, the paper investigated the community composition of phytoplankton of the Heiyu Lake in Daqing. The results show that there is an increasing by 36 to 52 genuses from 2005. These 52 kinds of phytoplankton respectively belong to 6 phylums, 32 families, and 52 genuses. The firstly dominant phytoplankton namely Bacillariophyta was substituted with Chlorophyta, and the changes of water quality displayed a trend from eutrophication to heavy eutrophication. It was preliminarily determined that water had subsjected to a certain degree of pollution. According to the assesment to phytoplankton, the natural fish productivity was in better state.
