Abstract: The phytoplankton community structure including species composition, density, biomass dominance and biodiversity of phytoplankton was surveyed in 5 sampling sites in Moguhu Reservoir in wet season (April), normal level season (July) and dry season (November) in 2016 in order to understand the phytoplankton in Moguhu Reservoir and current eutrophication in waters in Moguhu Reservoir.There were 90 species (genera) of phytoplankton were identified including 12 dominant species, with good phytoplankton diversity and relatively stable community structurein Moguhu Reservoir.The phytoplankton community structure was dominated by blue-green algae and green algae throughout the year, with average density of phytoplankton was (817 ±982)×104 cells/L, and the biomass was(6.72±5.88)mg/L.The significantly seasonal changes in phytoplankton biomass and density were found(P<0.05), the maximum in July (summer) and the minimal in April (early spring), indicating that the water quality in Moguhu Reservoir is under V class water standand in the year.The CANOCO software analysis revealed that the main environmental factors affecting the dominant species of phytoplankton are temperature, nitrate nitrogen and nitrite nitrogen levels, Moguhu Reservoir is currently under eutrophication pollution, with significant correlation between temperature and density and biomass of phytoplankton.
