| 摘 要： |  在2015年夏季和冬季开展了南海北部海域不同粒级浮游动物碳稳定同位素特征的研究。按照浮游动物粒径大小将其分成3个类群：小型(180~380 μm)、中型(380~500 μm)和大型(>500 μm)。研究结果表明，浮游动物δ13C值空间分布差异明显，夏季浮游动物δ13C值变化范围为–24.19~ –19.57，小型和中型浮游动物δ13C值的高值均分布在研究海域南部；冬季浮游动物δ13C值变化范围为–23.89~ –19.69，空间分布特征与夏季相反。浮游动物δ13C值未表现出显著的季节和粒径结构差异。各粒级浮游动物δ13C值与叶绿素a平均浓度的对数值均呈显著的正相关，而与浮游动物生物量相关性不明显。  |

| Abstract: | The stable carbon isotope of size fractionated zooplankton was studied in the northern South China Sea during summer and winter, 2015. The zooplankton was divided into three groups according to size structure, i.e., micro- (180–380 μm), meso- (380–500 μm) and macro- (>500 μm). Significant spatial difference of zooplankton stable carbon isotope was found. The δ13C value of zooplankton ranged from –24.19 to –19.57 in summer. High δ13C value of micro- and mesozooplankton mainly distributed in south of the survey area. The δ13C value of zooplankton ranged from –23.89 to –19.69 in winter, while the spatial distribution situation was opposite. No obvious seasonal and size fractionated change of δ13C value has been found. The δ13C values of size fractionated zooplankton were positively related to the numerical value of mean chlorophyll a concentration, but showed no significant correlation to zooplankton biomass. |
