| 摘 要： | 根据2004年5月、8月、11月和2005年2月南麂列岛海洋自然保护区海域调查资料,阐述了该海域浮游动物丰度和生物量的时空分布,探讨了其与环境因子的关系,并分析了保护区建区14a后丰度和生物量的变化以及不同季节生态类群丰度的组成特点。结果表明,浮游动物丰度和生物量季节变化明显,8月丰度最高,为(267.05±100.94)ind./m3,其他依次为11月、5月和2月;5月生物量最高,为(403.64±331.41)mg/m3,其他依次为8月、11月和2月;相关性分析表明,浮游动物丰度与生物量之间存在明显的正相关,相关系数为0.763,丰度、生物量与水温呈显著的正相关;与无机氮、活性磷酸盐表现为负相关;与浮游植物细胞丰度和叶绿素a含量未表现出相关性;与1990年相比,2004年春季浮游动物丰度和生物量均有所下降,秋季变化不大;不同季节各生物类群丰度和百分比均有差异。

| Abstract: | On the basis of the data of zooplankton collected in the Nanji Islands Marine Nature Reserve sea area in May, August, November of 2004 and February of 2005, this paper analyzed the temporal and spatial distribution of zooplankton abundance and biomass, its relations to environmental factors, the comparison between 2004 and 1990, and the characteristics of ecotypes abundance composition in four seasons. The results showed that there were significant seasonal variation of zooplankton abundance and biomass in the surveyed sea area. The highest abundance was observed in August, followed by November, May and February. The biomass peaked in May, followed by August, November and February. The abundance was very positively correlated to the biomass. The abundance and biomass of zooplankton was positively correlated to the temperature, negatively correlated to IN and PO4-P, and not correlated to the abundance of phytoplankton and the content of chlorophyll a. The abundance and biomass of zooplankton in Spring of 2004 was lower than that of 1990. The composition of ecotypes abundance showed certain seasonal variation. |
