摘要:

溶解有机碳(DOC)是海洋中最大的有机碳库,其中化学性质不稳定的成分大部分来自海洋浮游植物的释放。简要回顾了浮游植物溶解有机碳释放研究的发展历史,从光合作用合成的溶解有机碳(PDOC)释放占初级生产力的比重,PDOC的化学组成,浮游植物DOC释放的途径与机制,PDOC释放的环境调控,浮游植物群落组成对PDOC释放的影响,以及浮游植物释放DOC对异养细菌的生态意义等方面对相关研究进行了综述和分析。讨论了浮游植物溶解有机碳释放研究的现状和存在的问题,并对PDOC初级生产力测定的推广和相关研究的深化提出建议。

Abstract:

Dissolved Organic Carbon (DOC) is the largest reservoir of organic carbon in marine system, even more important is the labile part, most of which come from the releasing of phytoplankton. In this paper, the research history of phytoplankton DOC release is reviewed. The major research topics in this research area are discussed, which include the ratio of photosynthetic DOC (PDOC) to primary production, the chemical composition of PDOC, the pathway and controlling mechanism of PDOC release, the ecological significance of the extracellular organic matter to heterotrophic bacteria, etc. The current status and deficiency of present research work are analyzed. There are still many scientific questions without uniform understanding in this field, which is a large open field for further extensive studies and improvement of research methods.
