| 中文摘要: |
| 2008年4月、7月和10月,在乌江下游彭水水库库区、坝下江段和库尾以上江段设16个采样断面对浮游甲壳动物进行了调查;共检出浮游甲壳动物29属、49种;其中,枝角类13属、21种,桡足类16属、28种;枝角类年均密度1.89个/L,生物量37.70μg/L,桡足类年平均密度0.78个/L,生物量5.49μg/L。浮游甲壳动物的季节变化比较明显,种类数以春季最多,秋季最少;水平分布呈现库区种类数相对较多,库尾及以上江段种类数相对较少,坝下江段受水库下泄水影响显著。 |

| Surveys on the crustacean zooplankton communities in Pengshui Reservoir were carried out in April, July，and October of 2008. There were 49 species in 29 genera of crustacean zooplankton in Pengshui Reservoir，among which 21 species in 13 genera was cladocera and 28 species in 16 genera was copepoda. The average distribution density of cladocerans and copepads were 1.89 ind. /L and 0.78 ind. /L，respectively，and their average biomass were 37.70 μg//L and 5.49 p, μg/L，respectively. With the season changes crustacean zooplankton experiences obvious variatioons. There were the most species in spring and the least in autumn. As for the horizontal distribution，more crustacean zooplankton in Pengshui Reservoir region were found，and relatively less in the reservoir end and downstream flow of Pengshui Reservoir. The species number of the crustacean zooplankton in Wujiang River below Pengshui dam was affected significantly by reservoir sluicing.
