大型海藻养殖与海洋碳汇:研究进展、关键机制及展望OA

Marine carbon sinks(blue carbon)serve as a core pathway for mitigating global climate change and achieving the strategic goal of carbon neutrality.The large-scale cultivation of macroalgae-the primary pro-ducers in coastal ecosystems-integrates economic value and carbon sink functions,playing an irreplaceable role in marine carbon cycles.This paper systematically reviews the recent research progress in macroalgae cultivation for blue carbon sinks,focusing on the whole-chain mechanism of macroalgal carbon fixation(car-bon uptake,conversion,storage,translocation,and sequestration),and summarizes three core methods for carbon sink potential assessment(direct assessment,indirect assessment,and model simulation).It further analyzes the regulatory effects of cultivated species,environmental factors,cultivation modes,and manage-ment measures on carbon sink potential,identifies key bottlenecks in current research,and proposes future re-search directions and industrial application prospects in line with the carbon neutrality goal and blue carbon industry demands.This review aims to provide systematic theoretical references and technical support for the coordinated development of macroalgae cultivation and blue carbon sink enhancement.
