摘  要：
20 0 2年 7月 2 2日对太平湖的浮游生物现状进行了研究。太平湖浮游生物种类共计61个种 (属 ) ,浮游植物有 39属 ,浮游动物为 2 2个种属。太平湖浮游生物量的特点是浮游植物高而浮游动物低。浮游植物量为 33 91mg/l,优势种群为硅藻门、绿藻门和裸藻门 ,从分布上看中、上游浮游植物量明显高于下游 ,上层高于底层 ;浮游动物量为0 45mg/l,优势种群为轮虫 ,其分布规律是上游高于中、下游 ,底层高于上层 ;浮游植物初级生产力为 1 2 66g/m2 ·d ,水柱日毛产量为 2 0 91gO2 /m2 ·d ,浮游生物可提供的鲢、鳙鱼产力为 2 1 1 63kg/hm2 。太平湖为超富营养型。

摘  要：
An stuady of the present condition of plankton on July,2002,in Taiping Lake A The result indicated: the plankton had 61 Genus, phytoplankton had 39 Genus, zooplankton had 22 Genus The number of phytoplankton was high, and that of zooplankton was low The biomass of phytoplankton was 33 91mg/L, Bacillariopllyta,Chlorophyta and Euglenophyta predominated; and the biomass of zooplankton was just 0 454 mg/L, predominating species was Rotaltoria The distribution of phytoplankton was different from that of zooplankton, the biomass of phytoplankton of upper and middle reaches was obviously higher than that of lower reaches, and the biomass of zooplankton was only high in the advanced position; the number of phytoplankton of upper level were evidently higher than that of lower level, was belong to the super nourishing type The phytoplankton elementary productivity of Taiping lake was 12 66g/m 2·d, the potential fish productivity was 211 63kg/hm 2 on the basis of plankton so the nutrimental condition of Taiping lake.
