| 摘 要： | 2006-2007年分4次对余姚四明湖水库水质理化指标、浮游生物群落结构进行了调查,并进行了多样性指数分析及渔产潜力估算。结果表明,四明湖水库浮游植物种类共计8门、47种(属),其中以绿藻为最优势类群,占总密度的36.2%;浮游动物共计3大类、30种,其中原生动占40%;浮游植物年均生物量为10.20mg/L,浮游动物年均生物量2.36mg/L。从水体理化指标数据来看,四明湖水库水质属于II～IV类;从浮游植物群落结构和多样性指数分析结果来看,水库属于富营养水平;根据相关公式估算四明湖水库的鱼产潜力为2076kg/hm2。

| Abstract: | An investigation on abiotic environmental factors, planktonic population and the potential fishery production was implemented in 2006-2007. The result has shown that the water in the eutrophic-type Siminghu Reservoir is between Class II-IV. The average biomass for the phytoplankton and zooplankton is 10.2mg/L and 2.36 mg/L respectively. The potential fishery yield is assessed at 992.25Kg/hec. |

| Keywords: | Siminghu Reservoir plankton potential fishery production trophic level. |
