2017年春季海口湾网采浮游植物和赤潮生物研究

Studies on Net-phytoplankton and Red Tide Organisms of Haikou Bay in the Spring of 2017

研究了2017年春季覆盖海口湾15个站位的网采浮游植物物种及其群落特征,共发现浮游植物6门47属114种(包括变种),物种主要以硅藻为主。浮游植物数量较高,平均为1 112.46×10^(3)cells/L。浮游植物优势种有中肋骨条藻Skeletonema costatum、劳氏角毛藻Chaetoceros lorenzianus和长菱形藻原变种Nitzschia longissima var. longissimi。调查期间,共发现赤潮生物43种,主要赤潮生物是中肋骨条藻和劳氏角毛藻。

Feature of phytoplankton community were studied based on the data of phytoplankton net samples from 15 grid stations investigated in spring in 2017 of Haikou Bay.Six phyla including 47 genera and114 species(including variety)are found in the survey area.The main phytoplankton group is diatom.Cell abundance is high in the Bay with mean value reaching 1112.46×10^(3) cells/L.The dominant species are Skeletonema costatum,Chaetoceros lorenzianus and Nitzschia longissima var.longissimi.In the 114 species 43 are red organism,including Skeletonema costatum and Chaetoceros lorenzianus.
