| 摘 要： | 系统地介绍了海洋浮游植物群落比生长率(μ)及其相关概念。介绍和比较分析了研究μ的细胞分裂周期法、生物化学指示物法、模型法和去除摄食者稀释法这4类方法，推荐去除摄食者稀释法作为中国近海μ研究的重要方法。比较各海区μ的分布规律，初步发现：① μ与群落物种组成密切相关；② μ在大洋低于近岸；③ μ在近岸中等营养高于富营养水域；④ 小粒径浮游植物μ高于大粒径浮游植物。但还有很多未知的情况，尤其是在中国海区此类工作还很薄弱，需加强，为更深入了解海洋生态系统奠定基础。

| Abstract: | The concept of marine phytoplankton community specific growth rate (μ) and its related concepts were discussed. The four basic methods for estimating μ, frequency of dividing cells, biochemical indices, model approaches, and dilution incubations without grazers were reviewed, among them the dilution method was recommend as standard method for preliminary investigations of μ in China seas. After preliminary comparing and analyzing the μ around the world, we found that (1) μ depends on taxa composition of target phytoplankton community, (2) μ is relatively higher in offshore waters than in open seas and oligotrophic waters, (3) μ is even higher in mesotrophic areas than in eutrophic areas in offshore waters, and (4) μ is higher in small cell dominated community than in big cell dominated community. Many things still poorly understand and more studies on μ are needed in China. |
