【摘要】 调查研究海州湾轮胎海珍礁试验区海域夏季浮游植物群落特征.鉴定出调查海域浮游植物2门21属38种,其中硅藻门17属33种,占86.84%,甲藻门4属5种,占13.16%;调查海域浮游植物网样的丰度范围7月为7.74×10~4~1.94×10~5个/m~3,平均1.27×10~5个/m~3,8月为6.24×104~1.11×10~5个/m~3,平均9.35×10~4个/m~3;调查海域浮游植物网样香农-威纳多样性指数3.52,均匀度指数0.926;轮胎海珍礁试验区香农-威纳多样性指数最高为3.88,显著高于对照区海域.轮胎海珍礁营造的海域生态环境与浮游植物丰度密切相关.更多还原

【Abstract】 The characteristics of phytoplankton community in the test sea area with tyres sea reef in Haizhou bay in summer were studied in the paper.There were 2phylum,21 genera and 38 species of phytoplankton identified in the waters.Among them,there were 17 genera and 33 species of Bacillariophyta,accounting for 86.84%,occupying an important position in the composition and community structure of phytoplankton and 4genera and 5species of Pyrrhophyta,accounting for 13.16%.In the investigation waters in July,the sample density of phytoplankton ranged from 7.74×10~4 to 1.94×10~5 cells/m~3,with an average of 1.27×10~5 cells/m~3.In August,the sample density of phytoplankton ranged from 6.24×10~4 to 1.11×10~5 cells/m~3,with an average of 9.35×10~4 cells/m~3.The mean value of diversity index of phytoplankton was 3.52,and the mean value of evenness was 0.926.The highest value of Shannon-Wiener index in the test area with tyres sea reef was 3.88,significantly higher than that of other waters.It was suggested that the phytoplankton abundance was closely connected with the marine environment formed by the tyres sea reef.更多还原
