中文摘要:

      利用2006年秋季和2007年春季在黄海中南部采集的浮游动物样品，分析了不同粒径浮游动物的能值、脂肪含量及C∶N比值及其随不同海区和季节的变化。结果表明，不同粒径浮游动物的能值、脂肪含量与C∶N比值无显著差异；仅黄海中部的浮游动物脂肪(P<0.05)和能值含量(P<0.01)存在显著的季节变化，春季的平均能值和脂肪含量高于秋季；脂肪含量无明显的地理差异，能值含量和C∶N比值有显著的地理差异。统计分析表明，脂肪含量与C∶N比值(春季P<0.01)，能值与C∶N比值(秋季P<0.01，春季P<0.01)，水分含量与能值(秋季P<0.01，春季P<0.01)之间具有显著的相关性。

英文摘要:

      Based on the sampling of zooplankton in autumn 2006 and spring 2007 in southern and central Yellow Sea, seasonal and spatial variations of size, fat, C∶N ratio and energy content of the zooplanktons were analyzed. There were no significant difference in energy content, fat content and C∶N ratio among the zooplankton of different size groups. Fat content (P<0.05) and energy content (P<0.01) of the zooplankton showed significant seasonal difference in central Yellow Sea, and the values in spring were higher than those in autumn. There was no spatial difference in fat content, but the spatial difference in energy content and C∶N ratio was significant. There were significant linear relationships between fat content (in spring P<0.01) and C∶N ratio (P<0.01 in autumn and spring), energy content and C∶N ratio (P<0.01 in autumn and spring), and water content and energy (P<001 in autumn and spring), respectively.
