摘　　要：于2012年秋季对庙岛群岛南部海域浮游植物和环境因子进行了调查,并利用多元统计分析了庙岛群岛南部海域浮游植物分布特征及其与水环境因子的关系。本次调查共发现浮游植物94种,细胞平均丰度为6.65×106cells/m3。浮游植物细胞丰度呈现从靠近陆域(南部,庙岛海峡)到海域(北部,长山水道)逐渐增加的变化特征。主成分分析(PCA)浮游植物的分布特征表明,浮游植物主要分布于调查海域的东部、北部和西部海域,即外海海域。冗余分析(RDA)讨论浮游植物的分布与环境因子的关系表明,水深、温度和总磷是影响庙岛群岛南部海域浮游植物分布的关键性环境因子。A detailed field survey of hydrological, chemical and biological resources was conducted in the southern wa- ters of Miaodao Archipelago in autumn 2012. The distribution of phytoplankton and its response to environmental fac- tors were investigated with multivariate statistical analysis techniques. Totally 94 taxa were identified. The abundance of phytoplankton was 6.65 x 106 cells/m3 and gradually increasing from Miaodao Strait （ close to land） to ocean （ far away from land ）. Characteristics of phytoplankton assemblages were identified using principal component analysis （PCA） ,while redundancy analysis （RDA） was used to examine the environmental variables that may explain the pat- terns of variation of the phytoplankton community. Based on PCA results ,the phytoplankton was mainly distributed in the eastern, western and northern water zone （waters far away from land）. RDA indicated that depth, water tempera- ture and total phosphorus had the most profound impacts on the phytoplankton assemblages.
