【摘要】 长山电厂温排水对库里泡湖浮游动物种类组成和数量变化的影响表明,增温对浮游动物的种类和数量增加有促进作用,多样性指数增大;强增温区(31—39.6℃)其种类和数量则减少,多样性指数下降.电厂冷却系统对浮游动物的机械损伤率为66—78%,但这种损伤对其数量未产生明显的危害.由浮游动物量估算了鳙鱼鱼产力,强增温可使水体鱼产力下降,弱增温则促进鱼产力提高.

【Abstract】 The changes in zooplankton’ s composition and quantity in Kulipao Lake which has being effected by thermal discharge from Changshan Power Plant were investigated. The number of species, the quantity and diversity index of zooplankton generally increased except in the area with very high temperature (31-39.6℃) during summer. The impingement ratio of zooplankton by cooling system of the plant was 66-78%, which did not show a significant perniciousness. Productivity of bigheadfish (Aristih-thys nobilis) was estimated.
