Abstract
In this study, spatial variations in the phytoplankton community of the Miyun reservoir (North China) were investigated over a 5-month period in 2009. The focus was on two cyanobacteria genera: Microcystis, a toxin-producing species, and Oscillatoria, a taste & odor producer. The dynamics of the phytoplankton community were represented by the dominance of cyanobacteria in summer and fall, followed by a short-term dominance of chlorophyta in late fall. In October, the diatom community showed high abundance. Maximum phytoplankton biomass was found in the northern shallow region of the reservoir, which had higher nutrient levels. The study revealed that environmental factors strongly influenced the growth of the cyanobacteria: the biomass of Microcystis was particularly affected by water temperature and mixing depth, while Oscillatoria biomass was influenced by total dissolved phosphorus in the surface and middle layers, and by the Secchi depth in the bottom layer. Abundant Oscillatoria biomass was observed in late September when the biomass of Microcystis had decreased, allowing more light to penetrate.
