The phytoplankton assemblage of Zhubi Reef, a closed coral reef in Nansha Islands (South China Sea, SCS) was studied in June 2007. A total of 92 species belonging to 53 genera and four phyla have been identified. The dominant taxa in the lagoon were the diatom Chaetoceros and cyanobacteria Nostoc and Microcystis, while in reef flats were cyanobacteria Trichodesmium erythraeum, dinoflagellates Gymnodinium and Prorocentrum. The species richness and diversity were consistently lower in the lagoon than in reef flats. Classification and nMDS ordination also revealed significant dissimilarity in phytoplankton community structure between the reef flat and lagoon, with statistical difference in species composition and abundance between them (ANOSIM, p=0.025). Nutrient concentrations also spatially varied, with ammonium-enrichment in the lagoon, while high Si-concentration existed in reef flat areas. Both nutrient levels and currents in SCS may play important roles in determining the composition and distribution of microalgae in Zhubi Reef and SCS.
2007 年 6 月，对南沙群岛渚碧礁（中国南海，SCS）的浮游植物群落进行了研究。共鉴定出 53 属 92 种，分属四个门。在泻湖的优势类群是硅藻角毛藻和蓝藻念珠藻和微囊藻，而在珊瑚礁坪上的优势类群是蓝藻红海束毛藻、甲藻夜光藻和原甲藻。泻湖的物种丰富度和多样性明显低于珊瑚礁坪。分类和 nMDS 排序也表明，礁坪和泻湖的浮游植物群落结构存在显著差异，两者的物种组成和丰度存在统计学差异（ANOSIM，p=0.025）。营养盐浓度也存在空间差异，泻湖中有铵盐富集，而珊瑚礁坪区则有高硅浓度。南海的营养盐水平和海流可能在决定渚碧礁和南海的微藻组成和分布方面发挥重要作用。
