同安湾浮游植物与赤潮生物的初步研究

Preliminary Studies On Phytoplankton And Red Tide Organisms In Tongan Bay

根据2002年5月对同安湾6个采样点所采集样品的分析,共鉴定网采浮游植物2门35属74种,其中硅藻门67种,甲藻门7种。优势种为奇异棍形藻(Bacillaris paradoxa),其次为海生斑条藻(Grammatophora marina)和中肋骨条藻(Skeletonema costatum),浮游植物种类以广温广盐种为主。调查期间共发现赤潮生物27种,主要种类有奇异棍形藻和中肋骨条藻等。同安湾赤潮的发生与海水中无机氮和活性磷酸盐含量高密切相关。

A study on phytoplankton from six stations in Tongan Bay was carried out in May 2002. 74 species were identified in total, with 67 of Bacillariophyta and 7 of Pyrrophyta . The dominant species included Bacillaris paradoxa, Grammatophora marina and Skeletonema costatum . 27 species of red tide organism were found, including Bacillaris paradoxa and Skeletonema costatum , etc. Inorganic nitrogen and phosphate has much bearing on the red tide occurrence in tongan Bay.
