| 摘 要： | 当前,世界各国均关注于减缓气候变暖、降低大气二氧化碳(CO_2)排放为核心目标的低碳和碳中和理念。海洋是地球最大的碳库,在降低大气CO_2浓度方面具有重要作用。地球上超过一半的生物碳由海洋生物完成。大型海藻栽培具有成本低、产量高、碳汇可计量、栽培可控性强等优势;在近海可形成产业化的蓝碳,是海洋碳汇值得推崇的可持续发展模式。此外,规模栽培大型海藻可解决栽培海区海洋酸化、低氧、富营养化、有害藻华等海洋环境问题。文章从大型海藻栽培、环境修复作用及综合效益评估等方面综述了大型海藻碳汇功能及其解决近海环境问题的潜力。大型海藻规模栽培是发展低碳经济、增加海洋碳汇、实现碳中和,以及解决近海环境问题的有效途径。

| Abstract: | All countries in the world are paying attention to low-carbon and carbon neutrality to achieve the mitigation of climate warming by reducing CO2 emissions. Ocean is the largest carbon pool on the earth and play an important role of carbon neutrality. More than half of the biological carbon on the earth is achieved by marine organisms. Among them, seaweed resources are abundant, with advantages such as low cost, high yield, measurable carbon sink, and strong cultivation controllability. Industrialized blue carbon can be formed offshore, which is a sustainable model for future development in coastal ecosystems. In addition, large-scale cultivation of seaweed can provide potential solutions to the global marine environmental problems such as ocean acidification, hypoxia, eutrophication, and harmful algal blooms. This review focuses on the function of seaweed carbon sinks, and seaweeds'' potential to solve coastal environmental problems in terms of cultivation, environmental bioremediation effects, and comprehensive benefit assessment. In conclusion, large-scale seaweed cultivation is an effective approach for developing low-carbon economy, increasing marine carbon sink capability, solving marine environmental problems, and finally achieving carbon neutrality. |
