海洋碳的源与汇

通过对海洋碳源汇最近研究成果的分析,剖析了海洋碳源汇的内涵,提出了“表观碳源汇”与“实际碳源汇”的概念,对海洋碳源汇不确定性的原因进行分析,提出碳参数测定不淮确与其关键生物地球化学过程不清楚是其根本原因,继而提出了海洋碳源汇研究应特别注重陆架边缘海碳循环过程研究,提高碳参数测定的淮确性和应深入研究控制碳循环关键的海洋生物地球化学过程是其研究关键。

Carbon sources and sinks in oceans

The new concepts of "Apparent Source and Sink" and "Realistic Source and Sink" are pointed out based on analyzing the intension and summary of carbon source and sink in oceans. And then, the main results of oceanic carbon source and sink were reviewed in this paper. On the basis of these facts, it is thought that the uncertainty of oceanic carbon source and sink is caused by the less accurate measurement of carbon parameters and the poor understanding to key controlling biogeochemical processes. The margin seas should be paid more attentive in the research of oceanic carbon source and sink. It is critical that improving determination accuracy of carbon system and revealing the key controlling biogeochemical processes must be developed in studying oceanic carbon source ang sink.
