    Abstract
  • Based on long-term monitoring of phytoplankton biomass and species in Three Gorges Reservoir, it was found that the water temperature was the key element to influence the succession of phytoplankton in Three Gorges Reservoir. In order to verify whether the water temperature is the key elements of the succession of phytoplankton in the reservoir, the interior control experiment was designed, and the relationship between the water temperature and phytoplankton biomass and community structure was analyzed. The results show that the water temperature is the key element affecting phytoplankton biomass and community structure (diversity). Under the water temperature of 16-25 ℃, phytoplankton biomass increases with the rising of water temperature; under 25-40 ℃, phytoplankton biomass decreases with the increase of water temperature; under 23-25 ℃, the maximum phytoplankton biomass and the largest community diversity of phytoplankton can be achieved.
