摘要
通过对福建兴化湾海域表层和柱状沉积物中甲藻孢囊的分析，共鉴定出10属29种（含不定种）甲藻孢囊．其中发现有毒种类7种：微小亚历山大藻（Alexandrium minutum）、多环旋沟藻（Cochlodinium polykrikoides）、多边舌甲藻（Hngulodinium polyedrum）、具刺膝沟藻（Gonyaulax spinifera）、链状裸甲藻（Gymnodinium catenatum）、网状原角管藻（Protoceratium reticulaturn）和锥藻斯氏藻（Scnppsiella trochoidea）．表层沉积物中总甲藻孢囊丰度值在13～88粒／g之间，柱状沉积物中总甲藻孢囊的丰度在40～105粒/g以内．通过与周边其他海域甲藻孢囊属种组成及丰度值对比，表明兴化湾甲藻孢囊的丰度值较高，并且7种有毒种类的存在对该海域发生有毒有害赤潮构成潜在威胁，相关政府部门及周围居民应加以重视和防范．
Twenty-night species in 10 genus of din surface and core sediment samples in Xinghua polykrikoides , Lingulodinium polyedrum , Gonyaulax oflagellate cysts including 7 toxic species are identified from the Bay, Fujian. They are Alexandrium minutum, Cochlodinium spinifera , Gymnodinium catenatum , Protoceratium reticulatum , and ScrippsieUa trochoidea. Density of dinoflagellate cysts rage from 13 cysts/g to 88 cysts/g in surface sediments and from 40 cysts/g to 105 cysts/g in core sediments. Density of the dinoflagellate cyst in Xinghua Bay could be high compared with those areas in nearby seas. The existence of 7 toxic species can be the potential source of toxic Harmful Algae Blooms（HABs） in Xinghua Bay.
