摘  要:
研究了2005年夏季罗源湾13个大面站(包括3个连续站)浮游植物的群落结构特征。共检出浮游植物3门43属77种,平均细胞丰度为1633.91×104/m3,其中硅藻在物种数量和细胞丰度上占绝对优势。主要优势种为中肋骨条藻Skeletonema costatum、尖刺伪菱形藻Pseudo-nitzschia pungens、丹麦细柱藻Leptocylindrus danicus和菱形海线藻Thalassionema nitzschioides,其中中肋骨条藻是罗源湾浮游植物的关键种。调查区浮游植物表层细胞丰度的平面分布呈现南高北低的趋势,浮游植物的垂直分布呈现从表层到底层逐渐减少的趋势。表层浮游植物的Shannon-Wiener指数和均匀度指数的分布显示罗源湾北部浮游植物群落结构更均匀稳定。

摘  要:
Features of phytoplankton community were studied based on the phytoplankton data of a 13 grid stations(including 3 anchor stations) investigation in the Luoyuan Bay from 26th to 28th September 2005.Three classes including 43 genera and 77 species were common found.The abundance and distribution of diatoms determined the total variation of the phytoplankton abundance.The dominant species were Skeletonema costatum,Pseudo-nitzschia pungens,Leptocylindrus danicus,and Thalassionema nitzschioides,and Skeletonema costatum was the Luoyuan Bay key species of phytoplankton in this season.The horizontal distribution of phytoplankton cell abundance was higher in the South of the Bay,lower in the North of the Bay.The vertical distribution of phytoplankton cell abundance was lower gradually from the surface layer to the bottom.The horizontal distribution of phytoplankton Shannon-Wiener index and Pielou index demonstrated north the Luoyuan Bay,the phytoplanktonic community structure is evener stably.
