摘　　要：2009年对桃林口水库浮游生物和底栖生物的生物量、组成和季节变化进行了调查,并估算了相应的鱼产力。结果表明:桃林口水库浮游植物生物量平均为5.154 mg/L,高峰出现在春秋季,优势类群为硅藻门;浮游动物生物量平均为3.216 mg/L,高峰出现在夏季,优势类群为桡足类和枝角类;底栖动物品种较单一,生物量平均为4.776 g/m2,高峰出现在夏季,优势类群为颤蚓(Tubifex sp.)。桃林口水库滤食性鱼类和底栖鱼类鱼产力分别为1013 t/a和11 t/a。An investigation on the hydrobiological resources of Taolinkou Reservoir was conducted in 2009.The results showed that the average biomass of phytoplankton was 5.154 mg/L,and its peak appeared in the spring and the autumn.The dominant species was Bacillariophyta.The average biomass of zooplankton was 3.216 mg/L and the peak was the summer.The predominating species were Copepoda and Cladocera.The average biomass of zoobenthos was 4.776 g/m2,and the peak was the summer.The dominant species was Tubifex sp.It was calculated that the potential fishery production capacity of Taolinkou Reservoir on the basis of the biomass of plankton and zoobenthos were 1 013 t/a and 11 t/a,respectively.
