中文摘要:
      在2007-2017年秋季,利用专业海洋调查船对整个南黄海海域开展了5个航次的浮游植物调查。结果发现:调查海域共有浮游植物371种,隶属4门108属。其中硅藻门有56属237种,甲藻门有24属98种,硅藻和甲藻是组成南黄海海域浮游植物最主要的两大类群。主要优势种有裸甲藻(Gymnodinium sp.)、柔弱拟菱形藻(Nitz.delicatissima)、蓝隐藻(Chroomonas sp.)、菱形海线藻(Thalassionema nitzschioides)、锥状施克里普藻(Scrippsiella trochoidea)和环沟藻(Gyrodinium spp.)等。2007年以来,南黄海浮游植物种类数呈明显上升趋势。浮游植物细胞密度平均为1.96×104个/L,年际变化较大。将调查结果与众多文献比对,共发现9种藻类为中国新记录藻种,其中有4种硅藻和5种甲藻。
英文摘要:
      Five surveys on phytoplankton community in the South Yellow Sea were carried out in autumns between 2007 and 2017 using a professional oceanographic survey vessel. A total of 371 phytoplankton species, 108 genera, and 4 phyla were identified. Diatoms and dinoflagellates were the most dominant groups in the studied area, with 237 species and 56 genera, and 98 species and 24 genera identified, respectively. The dominant species were Gymnodinium sp., Nitzschia delicatissima, Chroomonas sp., Thalassionema nitzschioides,Scrippsiella trochoidea, and Gyrodinium spp. The total number of phytoplankton species was significantly increased since 2007. while the cell density largely varied over time, with an average of 1.96×104 cells/L. Referring to the published data to date, 9 species were recognized as new records in study areas, including 4 diatom and 5 dinoflagellate species, respectively.
