摘　　要：研究了2007年春季和夏季辽宁省锦州湾16个大面站网采浮游植物的群落结构特征。共检出浮游植物4门38属59种,在两个季节的调查中硅藻在物种数量和细胞丰度上占绝对优势。春季平均细胞丰度为5.44×104/m3,主要优势种为中肋骨条藻Skeletonema costatum和具槽帕拉藻Paralia sulcata;夏季平均细胞丰度为9.73×104/m3,主要优势种为扭链角毛藻Chaetoceros tortissimus和劳氏角毛藻C. lorenzianus。锦州湾春季细胞丰度高值区位于湾西部和东南部;夏季细胞丰度则呈现西高东低的分布趋势。两季节浮游植物的Shannon-W iener指数值均较高,表明锦州湾春夏季浮游植物群落结构较稳定。The features of phytoplankton community were studied based on the netz-phytoplankton data in a 16 grid stations investigation in spring and summer,2007 in the Jinzhou Bay. Four classes including 38 genera and 59 species were common found. The abundance and distribution of diatoms determined the total variation of the phytoplankton abundance. The average cell abundance was 5.44×10^4/m^3 in spring and 9.73 ×10^4/m^3 in summer. The dominant species were Skeletonema costatum and Paralia sulcata in spring and Chaetoceros tortissimus and C. lorenzianus in summer. The horizontal distribution of phytoplankton cell abundance was higher in west and southeast area in spring. In summer it was higher in the west, lower in the east. The high index of the value of phytoplankton Shannon-Wiener shows that the phytoplankton community structure was stable in Jinzhou Bay.
