摘　　要：研究了2006年夏季渤海湾赤潮重点监控区6个测站大面积调查的网采浮游植物物种及其群落特征,共发现浮游植物5门32属60种,物种主要以硅藻为主,但甲藻在群落中的比重也很明显,在个别站位上成为优势类群.优势物种主要为格氏圆筛藻(C.granii Gough)、星脐圆筛藻(C.asteromphalus)、琼氏圆筛藻(C.jonesianus)和中华盒形藻(Biddulphia sinensis).细胞丰度的站位分布主要由浮游硅藻的分布所决定,其高值区分布在4号站位.Features of phytoplankton community sampled by nets in the dominant area monitoring red tide in Bohai Bay were studied at 6 grid stations in summer, 2006. The phytoplankton samples were analyzed and the data indicated that five classes, including 32 genera and 60 species were commonly found in the survey stations. The main phytoplankton was diatoms, but the dinoflagellates were also important in the phytoplankton community, becoming the dominant group at some study stations. The dominant species were C.granii Gough, C. asteromphalus, C. jonesianus and Biddulphia sinensis. Phytoplankton cell abundances in the 4 stations were determined by the cell abundance of diatoms, which reached the maximum at the fourth station,
