摘要
1987，4～2003，4，在后湾水库作了三次浮游植物的采集．经鉴定有5门61属167种及变种和变型，其中以硅藻门和绿藻门占优势．以污水生物系统法对后湾水库的水质进行评价的结果表明，该库的水质基本为β-中污型．
In the reservoir, algae are the primary producers, the quantity are related to some condition factors. In addtion, they are related to the water trophic level. Nowdays people have noticed the relationship betwecn reservoir and algae, so advanced studies on algae in the reservoir are being carried out. An investigation of the phytoplankton from Houwan Reservoir was undertaken which was from 1987 to 2003,sampling three times. In the research, 167 species （including varieties and forms） have been found, representing 5 divisions, 61 genera. Bacillariophyta and Chlorophyta were the most diversified division. From the results we can see that the species number of 1987,2002,2003 is different,is 58 species,114 species and 73 species respectively. Using the Saprobic System,we conclude that the water quality of Houwan Reservoir is approaching to β-mesosaprobic.
