摘要
都西庙水库初级生产者只有浮游植物,它对太阳能年总辐射量的利用率为0.07%,生态学效率分别为10.5%、0.26%、6.40%,综合鱼产力为17.8g/m^2,各种经济鱼类对浮游植物的能量利用率为0.55%,表明牧食链中能量流动与分配不合理。本文对科学利用和保护该库饵料资源提出了建议。
There are only phytophankton in the primary producer of this reservior,and the rate of uti- lization of the total sun radiation was 0.07%.The ecological efficiency was separately differ- ent.The rate of energy utilization of phytophankton by various economic fishes was 0.55%.It was not reasonable that the energy flowed and distributed in the herd food chain.This paper of- fers some suggestions for scientific utilizing feed resource and protecting them.
