摘　　要：In the spring of 2007,a Synechococcus sp. bloom was monitored in station A1( 30° N,123° E) in the East China Sea. The abundance of Synechococcus sp. was nearly 2×10~6 cells/ml,and the contribution of Synechococcus sp. to chlorophyll a was nearly 90%. According to the abundance of Synechococcus sp. in the East China Sea and adjacent Changjiang River estuary in the past tow decades,the main reasons why Synechococcus sp. could form a bloom are listed below: the rising level of nutrients and the further eutrophication of the water body provided sufficient nutrients for Synechococcus sp.;with the global warming,the sea water temperature in the East China Sea rose continuously;the number of major predator heterotrophic flagellates was at a low level,reducing predation pressure.
