摘      要：Reservoirs are an important water source in many densely populated areas in southwest *** play an essential role in maintaining the structure and function of reservoir *** the succession in phytoplankton communities and the factors driving it are essential for eff ective water quality management in drinking water *** this study,water samples were collected monthly at the surface layers from March 2016 to December 2019 in Hongfeng Reservoir,southwest *** relationship between functional group succession was analyzed based on nonmetric multidimensional scaling analysis(NMDS),redundancy analysis(RDA),succession rate,and other analysis *** results showed distinct shifts in the community structure of phytoplankton functional groups within study *** Cyclotella *** dominant in 2016 and 2017,and Pseudanabaena limnetica was the dominant group in 2018 and *** appears that the phytoplankton composition and biomass are closely related to the water temperature and nutrient status in this *** results clearly showed that the permanganate index(COD_(Mn))was the key factor of dramatic phytoplankton functional group succession,and the change in succession rates was closely caused by total nitrogen concentration(TN).Therefore,the succession pattern and key factors of Hongfeng Reservoir revealed in this study were important guidance for the management of drinking water reservoirs in southwest China.A reasonable limit on exogenous nutrient input should be a priority,especially in high water temperature period.
