摘　　要：通过对福建省厦门湾、闽江口海域、三沙湾三个主要河口海湾144个站位表层沉积物样品中甲藻休眠孢囊的系统分析,根据甲藻休眠孢囊的形状、外壁结构、颜色、表面修饰物等形态特征共鉴定出9属25种及不定种,并对各孢囊属种的特征进行了分类描述,其中有毒甲藻休眠孢囊2种,即Alexandrium minutun,A. tamarense, 有害种类4 种, 即Alexandrium affine,Lingulodiniumpolyedrum,Scrippsiella trochoide.通过对比表明Alexandrium affine,A. minutum,Diplopeltacf. parva,Polykrikos cf. schwartzii,Protoceratium reticulatum,Protoperidinium minutum,P.cf. minutum,P. cf. americanum 以及Alexandrium sp.,Protoperidinium sp.1,P. sp.2等11种甲藻休眠孢囊为本次在福建省海域新发现的种,这些新发现的甲藻种类可能是近年来通过国际间往来的航运船只在我国沿岸海域排放压舱水或贝类引种带来的.Recent marine sediment samples from 144 stations in the Xiamen Bay, the Minjiang Estuary and the Sansha Bay in China were collected for living dinoflagellate resting cysts analysis. On the basis of morphological features of cysts, 25 species dinoflagellate living cysts are classified and their characteristics are described, including two toxic species:Alexandrium minutun, A. tamarense and four harmful species: Alexandrium affine, Gonyaulax spinifera, Lingulodinium polyedrum, Scrippsiella trochoidea. The species, such as Alexandrium affine, A. minutum, Diplopelta cf. parva, Polykrikos cf. schwartzii, Protoceratium reticulatum, Protoperidinium minutum, P. cf. minutum, P. cf. americanum, Alexandrium sp., Protoperidinium sp.1, P. sp.2, are first recorded in the sea area of Fujian Province, China, which may be brought by the discharge of ballast water from international shipping or by introducing shellfish into these sea areas in recent years.
