以往的研究报道了梯级水库建设引起的生物群落的显著变化。然而，调节高山梯级水库系统浮游生物时空格局的因素尚未得到充分的探讨。通过对黄河上游高山梯级水库系统浮游植物和浮游动物群落结构及环境因子的研究，探讨了环境因子对浮游生物纵向格局的影响。研究结果表明，在所研究的梯级水库系统中，浮游植物和浮游动物的物种数主要受水文情势的调控，而营养条件对物种数的影响并不显著。梯级水库的浮游植物数量和生物量受水文情势和营养盐条件的影响。梯级水库的排流率、氮磷比和含沙量与浮游植物的丰度和生物量呈负相关。浮游动物的丰度和生物量与水文情势没有显着相关性，但与梯级水库的营养条件呈强正相关。浮游植物的Shannon-Wiener指数（H '）和Pielou指数（J）主要受流域水文情势因素的影响，如梯级水库的排沙率和含沙量。温度和营养盐条件是影响浮游动物Shannon-Wiener指数（H '）和Pielou指数（J）的主要因子。浮游植物的种类数、丰度和生物量与浮游动物的种类数、丰度和生物量呈显著正相关。水动力和营养条件对浮游植物和浮游动物群落结构的调节作用不同。这些研究结果提供了一个了解的因素，调节纵向浮游生物群落模式的级联水库系统。
Previous studies report significant changes on biotic communities caused by cascade reservoir construction. However, factors regulating the spatial–temporal plankton patterns in alpine cascade reservoir systems have not been fully explored. The current study explored effects of environmental factors on the longitudinal plankton patterns, through a 5-year-long study on the environmental factors and communities of phytoplankton and zooplankton in an alpine cascade reservoir system located upstream of Yellow River region. The findings showed that phytoplankton and zooplankton species numbers in the studied cascade reservoir system were mainly regulated by the hydrological regime, whereas nutrient conditions did not significantly affect the number of species. Abundance and biovolume of phytoplankton in cascade reservoirs were modulated by the hydrological regime and nutrient conditions. The drainage rate, N:P ratio, and sediment content in cascade reservoirs were negatively correlated with abundance and biovolume of phytoplankton. Abundance and biovolume of zooplankton were not significantly correlated with the hydrological regime but showed a strong positive correlation with nutrient conditions in cascade reservoirs. Shannon–Wiener index (H’) and the Pielou index (J) of phytoplankton were mainly regulated by the hydrological regime factors, such as drainage rate and sediment content in cascade reservoirs. However, temperature and nutrient conditions were the main factors that regulated the Shannon–Wiener index (H’) and the Pielou index (J) of zooplankton. Species number, abundance, and biovolume of phytoplankton showed a significant positive correlation with those of zooplankton. Hydrodynamics and nutrient conditions contributed differently in regulating community structure of phytoplankton or zooplankton. These findings provide an understanding of factors that modulate longitudinal plankton community patterns in cascade reservoir systems.
