摘要
采用生物学方法对二龙湖水库不同样站浮游植物进行调查研究，根据浮游植物种群组成、数量、生物量及多样性与污染程度的相关性进行水质评价，结果表明：二龙湖水库湖心及出水口处水质较好，东辽河及北大河入口处水质较差，二龙湖水库水质基本属于β－中污带类型．
This paper takes biological methods to investigate the water quality in Erlong hu reservior in Siping city. Water quality assessment was conducted according to the composi- tion, quantity, biomass of phytoplankton, as well as the correlation between phytoplankton community diversity and pollution level. The investigation results indicate that the water quality in the middle is as good as that at its exit, but the water quality is not so good at its entrance to Dongliao river and Beida river. Therefore, the water quality in Erlong hu reserv- ior basically belongs to the β-type of moderately polluted type.
