【Abstract in Chinese】 通过对2011年小浪底水库调水调沙对浮游生物群落结构的分析表明,调水调沙前后浮游植物种类组成变化不明显,都是以硅藻门占优势,但是密度、生物量显著下降;浮游动物中轮虫种类明显减少,大型浮游动物甲壳类及枝角类部分消失,浮游动物密度、生物量显著下降。

【Abstract】 It analyzes the plankton community composition of a regulated discharge regime of the river from June to July in 2011.The results showed that: the change in composition of phytoplankton was not obvious and the dominant species is Bacillariophyta,but the density and biomass of phytoplankton showed significant decline;A significant reduction in composition of Rotifer,the density and biomass of zooplankton descended obviously.
