| 摘 要： | 根据2016年3月30日—4月3日在三沙湾采集的浮游植物水样，共发现浮游植物3门22属38种，其中硅藻门19属34种，占总种数的89.47％，是调查海域的主要类群；甲藻门2属3种；金藻门1属1种。春季浮游植物平均数量为1.63×105 cells/L，数量高值区出现在三沙湾西北方向的交溪、白马港区和卢门港区及附近海域。优势种为中肋骨条藻（Skeletonema costatum），出现频度达100%，主要分布在河口区附近。运用冗余分析（redundancy analysis，RDA）探讨浮游植物与环境因子之间的关系，结果表明影响三沙湾春季浮游植物的关键环境因子是溶解氧、盐度、水温和活性磷酸盐。

| Abstract: | Based on the analysis of water samples collected at Sansha Bay during March 30 to April 3, 2016, totally 38 species belonging to 3 phyla and 22 genera were identified, including 34 diatom species belonging to 19 genera, accounting for 89.47% of the total species and it is the main group in the investigated sea area. 3 dinoflagellate species belonging to 2 genera, and 1 chrysophyta species belonging to 1 genus. In spring, the average abundance of phytoplankton was 1.63×105 cells/L. The high value area appears in northwest to Shasha Bay, the Jiaoxi river, Baima port and the waters near the Lumen port. The dominant specie was the Skeletonema costatum, the frequency of occurrence was 100%,but it was mainly distributed in the estuary. The relationship between phytoplankton and environmental factors was studied by Redundancy Analysis(RDA).The results of Redundancy Analysis(RDA) indicated that Dissolved Oxygen (DO),Salinity (SAL), Temperature (T), and Soluble Reactive Phosphorus (SRP),were the most important environmental factors influencing phytoplankton of Sansha Bay in spring. |
