摘    要:研究了2006年夏季浙江海域(120°~128°E,26°~30°N)91个站位赤潮生物物种组成及群落分布,共检出赤潮生物4门30属69种,其中角毛藻属和原多甲藻属种类数占优势.赤潮生物种类数及数量分布由近岸向外海递减且有随水深增加而减少的趋势,高值区为舟山群岛和南麂列岛海域.舟山群岛海域夏季赤潮生物优势种为旋链角毛藻,是新的引发赤潮的潜在藻种;南麂列岛海域夏季赤潮生物优势种为中肋骨条藻,与往年调查结果相符.舟山群岛和南麂列岛海域仍然是浙江海域赤潮发生敏感区.

关 键 词:赤潮生物  群落分布  浙江海域  舟山海域  南麂列岛

Abstract:The composition of red tide plankton and distribution of community in Zhejiang coastal waters(120°~128°E,26°~30°N)were studied at 91 stations in summer, 2006. In total, four classes, including 30 genera and 69 species were commonly found at the survey stations. Chaetoceraceaes and protoperidiniums were the most important dominant species. It was found that the species and cell abundance of the red tide plankton depressed from offshore to open sea, from surface to bottom. The largest values of biomass were Zhoushan sea area and Nanji Islands. The dominant specie in Zhoushan sea was Chaetoceros curvisetus, which was new specie to bring on red tide. The dominant specie in Nanji Islands was Skeletonema costatum, which is coincided with the result of past investigation. Zhoushan sea area and Nanji Islands were still the vulnerable areas of red tide in Zhejiang coastal waters.
Keywords:red tide plankton  community  Zhejiang coastal waters  Zhoushan sea area  Nanji Islands
