| 摘 要： | 总结并评述了对海洋中的Redfield比值进行修正的研究成果。通过对文献结果的综合分析,获得了一些规律性认识：N／P=16这一传统的Redfield比值被广泛接受,个别大洋深层水中N／P比值小于16可归因于脱氮作用;海洋中实际的-O2／P和C／P比值大于传统的Redfield比值;海洋中浮游生物的实际元素组成中C／H、C／O比值显著高于Redfield给出的浮游生物元素组成中的比例。

| Abstract: | In this paper, the studies on the modification of Redfield ratios in the world ocean are reviewed. It is concluded from the combinational analysis of different research results that the traditional value of 16 for N/P ratio is widely accepted, and the N/P rations less than 16 in some deep waters attributed to the denitrogenation; the actual ratios of -O_2/P C/P in the ocean are greater than the traditional Redfield ratios; and the actual ratios of C/H and C/O in the elemental composition of marine plankton are significantly greater than those given by Redfield. |
