海洋浮游植物与生物碳汇

系统描述了浮游植物与海洋碳汇相关的几个过程:初级生产、浮游植物沉降、浮游动物粪球打包沉降、经典食物链碳汇、溶解有机碳生产和转化、透明胞外聚合颗粒物(TEP)凝聚网,和CO₂分压升高(海水酸化)影响下浮游植物功能群转变及中国海可能的生物碳汇前景展望。提出海洋初级生产过程和TEP凝聚网过程是中国海生物碳汇的关键过程,而中国海的黄海中部及长江口区域是生物碳汇研究的重点区域,建议将硅藻及其碳汇过程作为今后研究的重点。

Marine phytoplankton and biological carbon sink

In this paper, we examined key processes for evaluating biological carbon sink in relation to marine phytoplankton in the China Sea. Current phytoplankton carbon-sink-related processes are discussed, including primary production, phytoplankton sinking, zooplankton fecal pellet package effects, the marine food chain, phytoplankton dissolved organic carbon production and subsequent bacterial repackaging, transparent exopolymer particles (TEP), and changes in phytoplankton functional groups under projected rising pCO₂. Marine primary production and the TEP aggregation web are specifically examined. Key regional study areas in China, such as the central Yellow Sea and the Yangtze River estuary, are also discussed, as well as suggestions for future biological carbon sink studies in China using diatoms, a keystone functional group.
