海草碳通量的卫星遥感检测研究进展

Progress in detecting seagrass carbon flux over optically shallow water using satellite remote sensing

近年来,对于海洋碳汇的研究已经越来越重视,但很多海洋碳汇的研究还处于发现阶段。海草生态系统是海岸带碳循环的重要组成部分,对于维持海岸带碳平衡和缓冲区域海洋酸化起到相当重要的作用。对海草生态系统碳通量及循环模式进行研究,可以为统计我国海洋碳通量提供第一手资料以及为寻找未知碳汇提供重要线索。文章主要综述了海草的碳汇过程、海草在海洋碳汇中的作用、影响海草碳汇的各种因素以及海草碳通量的卫星遥感检测方法和模型等。

In recent years, more and more attention has been paid to ocean carbon flux, which leads to new discovery of ocean carbon sinks. Studying carbon flux and carbon cycle of seagrass ecosystem can provide first-hand data for calculating ocean carbon flux in China and for finding new carbon sinks. In the paper, the authors summarized seagrass carbon flux process, effects of seagrass on ocean carbon flux, factors affecting seagrass carbon flux, and satellite remote sensing methods and models. The review can provide guide for how to study seagrass carbon flux.
