摘　　要：随着工业化进程的加快,大气CO_(2)浓度持续升高,加剧了全球气候变化。海洋碳汇作为实现碳中和的重要途径,具有重要的生态和经济价值。海洋生态系统中大型海藻的固碳能力在缓解全球气候变化方面有着巨大潜力,而海藻的光合响应易受多种环境因子如CO_(2)浓度、盐度、温度、光强、光质的影响。为了做好后续研究的必要储备,不断优化海藻的栽培技术,本综述全面汇编了大型藻类基于以上五种环境因子变化的光合生理特征的最新信息,分析其特点主要表现为:不同藻属光合响应机制不同;海藻生长速率与各环境因子浓度供应并不是呈单一的线性关系,而是有一定阈值;藻体面对环境胁迫时会启动一定的调控机制维持自身正常生长状况。With the acceleration of industrialization,atmospheric CO_(2)concentrations continue to rise,exacerbating global climate change.As an important way to achieve carbon neutrality,marine carbon sinks have important ecological and economic value.The carbon sequestration capacity of macroalgae in marine ecosystems has great potential to mitigate global climate change,and the photosynthetic response of seaweeds is susceptible to a variety of environmental factors such as CO_(2)concentration,salinity,temperature,light intensity and light quality.In order to make the necessary reserves for follow-up research and continuously optimize the cultivation technology of seaweed,this review comprehensively compiles the latest information on the photosynthetic physiological characteristics of macroalgae based on the changes of the above five environmental factors,and analyzes the main characteristics of the photosynthetic response mechanisms of different algae.There is not a single linear relationship between the growth rate of seaweed and the concentration supply of various environmental factors,but has a certain threshold.In the face of environmental stress,algae will activate certain regulatory mechanisms to maintain their normal growth.
