福建南日岛周围海域浮游动物的种类组成与数量分布特征

对2008年10月、2009年5月南日岛周围海域浮游动物种类组成和数量分布特征及其与环境因子的关系进行了研究。结果表明,南日岛周围海域已鉴定的浮游动物有94种,分为5个生态类群,以沿岸暖水类群和广温广盐类群为主。春、秋两季调查海区浮游动物湿重生物量均值为198.7 ind/m^3,其中春季均值为119.4 mg/m^3,秋季均值为278.0 mg/m^3,秋季为春季的2倍。平面分布上,春季高值区出现在南日岛西南部海域,而秋季出现在北部的小日岛西北侧海域。春、秋两季浮游动物的丰度和生物量的平面分布趋势基本一致。

Abundance and distribution of zooplankton in waters around Nanri Island of Fujian

Based on the samples collected from the survey in waters around Nanri Island during the period of October 2008 and May 2009 , the analysis showed that there were 93 species in the surveyed areas . The zoo-plankton can be divided into 5 ecotypes, among them, coastal warm water groups, eurythermal, eurysalinity groups were dominated. The species diversity of zooplankton was higher in autumn than that in spring. In spring the highest biomass of zooplankton was located in the south-west part of Nanri Island. In autumn the highest biomass of zooplankton was located in north part of Nanri Island. The distribution of zooplankton and its relations with environmental factors were also analyzed.
