摘　　要：休眠包囊是甲藻生活史中的一个重要阶段,它们对于甲藻种群的生存、延续以及扩散具有重要的生物学意义。能够形成休眠包囊的甲藻大部分时间以包囊的形式存在于沉积物中,因此研究包囊有助于揭示甲藻的物种多样性。根据沉积物中甲藻包囊的种类和数量还可以追溯各海区的富营养化历史,以及重建古海洋环境。本文介绍了甲藻包囊的研究方法,指出形态分类需要结合萌发实验对营养细胞进行观察。中国近20年来的研究共记录了甲藻包囊25属67种(以生物学名称为准),我们整合文献资料列出了中国沿海甲藻包囊物种名录。其中种类最多的是原多甲藻属(Protoperidinium),有18种,其次是施克里普藻属(Scrippsiella)、膝沟藻属(Gonyaulax)和亚历山大藻属(Alexandrium),分别有9种、7种和5种,其余的属在1–3种之间。我国之前的研究多局限在形态的鉴定而缺乏足够的萌发实验支持,故部分种类的鉴定还有待验证。最后,我们分析了中国甲藻包囊研究应该注重的研究方向。The resting cyst plays an important role in the life cycle of certain dinoflagellates.Cyst formation is of great significance to populations in terms of perseverance and dispersal.Dinoflagellates producing cysts spend much more time in the sediment than in the water column,and studies on cysts help to uncover dinoflagellate diversity.Cyst diversity and abundance within sediments can reflect the history of overlying dinoflagellates and environmental conditions,and thus serve as a historical record of phytoplankton commu-nity and environmental changes.By analyzing the amount and relative proportion of different cysts,the pa-leo-oceanographical environment can be reconstructed.Here we review recent progress in the study of di-noflagellate cysts within China＇s seas.We point out the insufficiency of identifying dinoflagellate cysts based solely on morphological characters,and stress the need to combine results with results of germination ex-periment.We integrated literature data and provide a checklist of dinoflagellate cyst in China seas： a total of 67 species from 25 genera are listed.Their biological and paleontological names as well as distributional ranges are given.The genus Protoperidinium is most rich with 18 species,followed by Scrippsiella（9）,Go-nyaulax（7）,and Alexandrium（5）;other genera contain 1–3 species each.In the present studies in China,species identification based mainly on morphological observations likely result in uncertain taxonomical classification of some species.Finally we discussed fruitful directions for further studies.
