摘　　要：建立了南黄海冷水团区域4个站位的正态化生物量粒径谱,运用连续模型计算出底栖动物群落的平均次级生产力为1.79g dwt.m-2.a-1,耗氧量为0.082 3mmol.m-2.h-1。结果表明,群落次级生产力和耗氧量之间具有相同的变化趋势,且都与正态化生物量粒径谱截距呈正相关,而与斜率无明显关系。小型底栖动物次级生产力和群落耗氧量与大型底栖动物相比没有显著差异。与固定P/B系数法计算的小型底栖动物次级生产力相比,利用正态化生物量粒径谱和连续模型计算的底栖动物群落次级生产力更为可靠。利用正态化生物量粒径谱和连续模型可以得到可信的底栖群落耗氧量结果。Several normalized biomass size spectra of benthic assemblages were constructed in the Southern Yellow sea. By the methods of the continuous model, the secondary production and oxygen consumption of macroand meiofuana were calculated. The mean value of secondary production in the studyed area is 1.79 g dwt·m^-2·a^-1 and the mean value of oxygen consumption is 0. 082 3 mmol·m^-2·h^-1. The secondary production as well as oxygen consumption shows a positive correlation with the intercept of normalized biomass size spectra. There is no significant difference between macrofauna and meiofauna in secondary production and oxygen consumption. Compared with the method following the formula P = 9B, the continuous model can produce more reliable evaluation of secondary production of meiofauna.
