有机碳在海洋环境中的长期保存机制一直是海洋碳循环研究的重点,也是研究气候变化与全球碳循环之间作用和反馈的关键。据估算,表层海洋沉积物中约20%的有机碳是通过与氧化铁的结合而保存下来的,因此与氧化铁结合是有机碳长期保存的关键因素之一。研究表明,有机碳—氧化铁复合物的形成主要通过吸附和共沉淀这2种机制,共沉淀反应是有机碳与氧化铁在海洋环境中结合的主导机制。不同来源的有机物在发生与铁氧化物的共沉淀或吸附作用时是有选择性的,在大部分海洋环境中铁氧化物优先与海洋有机碳结合,但在河口三角洲区域,铁氧化物优先与陆源有机碳结合。大量的陆源输入,较高的初级生产和频繁的再悬浮活动使河口边缘海特别适于开展有机碳—氧化铁结合的相关研究,这也是今后研究的重点方向。

Understanding the mechanisms responsible for long-term storage of organic carbon (OC) in marine environment is important for studying the marine carbon cycling and predicting how the global carbon cycle will respond to climate change. It is estimated that more than 20% of the OC in marine sediments is associated with iron oxides and thus these complexes are one of the most important factors in the long-term storage of OC. The OC-iron oxide (OC-Fe) association can be formed through either adsorption or co-precipitation, but the dominant mechanism of OC-Fe association in marine environments is co-precipitation. The combination of OC from different sources with iron oxides is selective. Iron oxides preferentially combine with marine OC in most marine environments, but in estuarine delta regions they prefer terrestrial OC. Due to large inputs of terrestrial materials, high primary production and frequent re-suspension, estuarine and marginal seas are suitable sites for OC-Fe association studies, which should be emphasized in the future.

Key words: Sedimentary organic carbon, Iron oxide, Complexation, Preservation, Carbon cycling.
