摘　　要：大型海藻光合作用是海域初级生产力的来源之一,是海洋碳循环中关键的一环。大型海藻可通过光合作用有效地吸收海水中溶解的无机碳以及大气中的CO2,将其转化为有机碳并释放O2,光合作用的产物除支持生态系统外,还以有机物的形式埋藏在沉积物中,进而形成碳的汇。大型海藻的养殖和增殖对CO2的减排、减缓海洋酸化、扩增海洋碳汇效应以及缓解气候变化都有重要意义。本文就大型海藻碳汇机理、潜力以及大型海藻碳汇能力的扩增途径进行了综述,为大型海藻碳汇效应研究的发展提供了依据。Macroalgal photosynthesis is a major source of marine primary productivity and a crucial part of the ocean carbon cycle. Macroalgae effectively absorb inorganic carbon dissolved in the ocean and CO2 in the air to produce or- ganic carbon and release 02 through photosynthesis. Besides supporting the ocean ecosystem, photosynthetically pro- duced products are deposited in the sediment in the form of organics to complete the carbon sink. Proliferation of macroalgae results in a significant decrease in CO2 concentration, mitigates ocean acidification, strengthens the effect of ocean carbon sequestration, and mitigates climate change. These results provide a general description of the mechanism and potential of macroalgae to contribute to the carbon sink and present ways to enhance ocean carbon sink capacity. The results provide a basis for developing a macroalgal carbon sink effects study.
