| 中文摘要: |
| 2010年7-8月对泾河宁夏段浮游生物群落组成进行了调查。结果表明,该河段浮游植物种类有6门、81种(属),密度为1.1万～11.6万个/L,平均密度为4.37万个/L。生物量为0.024～0.210mg/L,平均生物量为0.083mg/L。浮游动物有4门、54种(属),密度为60～185个/L,平均密度为107.73个/L。生物量为0.02～0.66mg/L,平均生物量为0.24mg/L。浮游植物多样性指数表明,该河段水质良好,浮游生物群落结构不稳定,易受外界的干扰。 |

| The compositions of plankton community in Jing River of Ningxia section were investigated from July to August in 2010. The results showed that:81 species(genera)，falling into 6 phyla of phytoplankton were observed in the river reach，with density of phytoplankton 1 .1 x 104-11.6 x 104 cells/L，average density 4. 37x104 cells/L, range of biomass 0.024-0.210 mg/L，and average biomass 0.083 mg/L. Meanwhile，54 species(genera)，in 4 phyla of zooplankton were observed，with density 60-185 ind/L，average density 107.73 ind/L, range of Biomass 0. 02-0. 66 mg/L，and average biomass 0. 24 mg/L. The richness index of plankton in JingRiver showed that water quality of the river reach surveyed was in good condition; plankton community was of structural instability，and hence was vulnerable to environmental changes.
