摘　　要：Phytoplankton are classfied into three groups based on size: microphytoplankton (>20 μm), nanophytoplankton (2-20 μm), and picophytoplankton (<2 μm) (Sieburth et al. 1978) [1]. Picophytoplankton are composed of three groups: Prochlorococcus, Synechococcus, and picophytoeukaryotes. The former two are unicellular cyanobacteria.Phytoplankton are classfied into three groups based on size： microphytoplankton （〉20 μm）, nanophytoplankton （2-20 μm）, and picophytoplankton （〈2 μm） （Sieburth et al. 1978）.
