摘要: 为了解海南省文昌市冯家湾海洋牧场及其附近海域的浮游植物群落结构特征,于2019年9月(秋季)和2020年3月(春季)对其海域浮游植物和环境因子进行了调查,并应用冗余分析(RDA)研究了该海域浮游植物群落结构及其与环境因子的关系。结果显示,春、秋两季共鉴定出浮游植物3门40属109种,主要由硅藻(78种)和甲藻(30种)组成。浮游植物密度季节间差异明显,秋季高于春季。秋季的主要优势种为中肋骨条藻(Skeletonema costatum),春季的主要优势种为粗根管藻(Rhizosolenia robusta)。秋季对照区丰富度指数、多样性指数和均匀度指数平均值均高于投礁区,春季则反之。冗余分析结果表明,盐度和水温分别是秋季和春季影响冯家湾浮游植物群落结构的主要环境因子。

Abstract: With the aim of understanding the community structure of phytoplankton of Fengjia Marine Pasture in Wenchang City, Hannan Province, the phytoplankton and environmental factors were investigated in September 2019 (autumn) and March 2020 (spring). The relationship between phytoplankton community structure and environmental factors was studied by redundancy analysis (RDA). The results showed that, a total of 109 phytoplankton species belonging to 3 phyla and 40 genera were identified,which mainly consisted of Bacillariophyta (78 species) and Dinophyta (30 species). The density of phytoplankton was significantly different between seasons, and it was significantly higher in autumn than in spring. The main dominant species in autumn was Skeletonema costatum, and the most dominant species was Rhizosolenia robusta in spring. In autumn, the average values of richness index, diversity index and evenness index in the control area were higher than those in the reef area, while in spring, these parameters in the reef area were higher than those in the control area. The result of redundancy analysis indicated that salinity and water temperature were the main environmental factors affecting the community structure in autumn and spring, respectively.
