摘　　要：研究了长春南湖水生生态系统中浮游动物群落的牧食力,结果显示,1996年夏季南湖浮游动物群落对水柱原位浮游植物和浮游细菌的牧食力分别为2.57kJ/(m2·h)和1.47μg/(l·h)(以碳量计),分别为浮游植物和浮游细菌同期净生产力的51.7%和32.9%,表明浮游植物和浮游细菌是南湖中浮游动物最重要的食物和能量供应者.浮游生物食性鱼类和捕食性浮游动物对于浮游动物群落牧食力的影响有待进一步研究.The grazing ability of zooplankton community of the Nanhu Lake aquatic ecosystem in Changchun was studied.In the summer of 1996,the in situ grazing abilities of zooplankton community on phytoplankton and bacteriaplankton were 2.57 kJ(m2·h)AND 1.47 μg/(l·h)(expressed as carbon amount) respectively in the Nanhu Lake,which were 51.7% of phytoplankton net productivity and 32.9% of bacteriaplankton net productivity in the same period.The result showed that phytoplankton and bacteriaplankton were the most important providers of food and energy for zooplankton in the Nanhu Lake.The effects of planktivorous fishes ad predatory zooplankton on the grazing ability of zooplankton community should be furthere studied.
