摘      要：The sea surface microlayer(SML)is the thin boundary layer between the ocean and the *** community in the SML is known as phytoneuston and has a different community structure and biomass from the phytoplankton of the underlying bulk *** this study,water samples were collected from the SML of Daya Bay in southern China in September,October,and December of *** growth potential(AGP)tests were conducted by adding different forms of nitrogen(N),phosphorus(P)and silicate(Si).Phytoneuston grew well with both inorganic and organic nutrients,and showed comparable community structure after nutrient addition.A total of 16 pigments were analyzed in the SML samples collected from Daya Bay in this *** were dominated by the cyanobacteria-diagnostic pigment(zeaxanthin,Zea)in September and October,and by diatom-diagnostic pigment(fucoxanthin,Fuco)in *** concentrations and proportions of Fuco increased greatly after the nutrient addition,and the concentrations and proportions of Zea decreased ***,the diatom pigment index(DiatDP)increased after nutrient addition,and the prokaryotic pigment index(ProkDP)conversely *** results suggested that massive occurrences of Zea and cyanobacteria are important characteristics of phytoneuston structure in Daya Bay especially in warm seasons,and nutrient addition especially Si addition promoted the growth of diatoms.
