Survey and adapted hydro-meteorological conditions of Noctiluca Scintillans red tides in South China Sea

This paper collects all events of Noctiluca scintillans red tide in South China Sea since 1980~2004 and analyses the space-time distribution and the duration of the red tides.The event that the red tides of Noctiluca scintillans had been replaced by other species and the possible causes are discussed.The paper also showed hydro-meteorological changes and evolution features on the occurrence of Noctiluca scintillans red tide with statistical approach.And at last,the optional water temperature are pressented for the ocurrence of Noctiluca Scintillans red tides in South China Sea.
