主　　题：harmful algal blooms dinoflagellate Daya Bay Scrippsiella trochoidea 

摘      要：Harmful algal blooms(HABs),such as dinoflagellate blooms,have adverse eff ects on coastal water environments,causing seafood contamination and aquaculture economic *** on historical HAB records data(1983-2017)and phytoplankton data(1982-2008),field investigation and laboratory experiments on frequently bloomed dinoflagellate species,we analyzed the possible mechanisms of high frequency dinoflagellate blooms in Daya Bay,South China *** HAB records data show that the proportion of dinoflagellate blooms increased from 15% before 1994 to 77.27% after *** bloom occurred mostly in summer(57.58%)in Yaling Bay(76.92%).The species inducing dinoflagellate blooms tended to be singular over time,with high proportion of Scrippsiella trochoidea(42.86%-88.88%).Laboratory experiment and field investigation of *** bloom showed that this species grew rapidly at 30℃ and 32.1℃(r=0.47,P7 m/s),which disturbed the resting cysts in the sediment and bring them into surface *** into account of environmental parameters,algae source,and atmospheric conditions,the probable mechanism of *** bloom could be *** cysts were resuspended by the spring tide or strong wind,germinated at the bottom layer,reproduced rapidly at higher temperature,and then aggregated in the inner bay(Yaling Bay),resulting the frequent *** *** the influences of global warming and human activities,it should be taken more attention that dinoflagellate blooms might increase along the coastal waters.
