　　根据2006~2008年夏季(7~8月)在象山港西部海域(121°37′E、29°40′N以西)进行的海洋调查资料，对该海域浅水Ⅲ型浮游生物网采集的浮游植物的种类组成与分布、年际变化以及与理化环境因子的相关性进行了研究。结果表明：调查海域夏季共鉴定到浮游植物54种，其中硅藻类占绝对优势，为48种，并可大体分为河溪淡水性、外洋性广布种和沿岸内湾性三大生态类群，优势种主要有丹麦细柱藻(Leptocylindrus danicus)、紧密角管藻(Cerataulina compacta)、中肋骨条藻(Skeletonema costatum)、琼氏圆筛藻(Coscynodiscus jondsiarus)等。根据环境因子与种类数的相关性分析表明，透明度和化学需氧量(COD)对浮游植物种类数影响最大，其次为活性磷酸盐(PO43?-P)，无机氮(DIN)、盐度、水温相对较小。与历史资料相比，调查海域夏季浮游植物种类数量存在明显年际差异，且仍处于波动状态。

Based on the survey of phytoplankton Ⅲ net in western Xiangshan Bay (west of 121°37′E, 29°40′N) in summer (Jul.~Aug.) from 2006 to 2008, the species composition, distribution, annual varations of phytoplankton and the relations to environmental factors were analyzed in this paper. The results showed that 54 species of phyto-plankton were identified including 48 species of Diatoms predominating absolutely over the others. There were three eco-groups, including freshwater rivers and streams, pelagic and widely distributed species and along the in-ner bay of eco-groups. The dominant species were Leptocylindrus danicus, Cerataulina compacta, Skeletonema costatum, and Coscynodiscus jondsiarus, et al. Based on analysis of the correlations between species number of phytoplankton and physical-chemical factors, it suggested that the transparency and COD impacted the species of phytoplankton most significantly, followed by PO43--P. While DIN, salinity and water temperature had relative little impact on it. By comparison with historical data, it indicated that there were significant inter-annual variations and this fluctuation situation still remains now.
