海南麒麟菜保护区大型海藻分布特征及碳储量研究

Abstract

Abstract:

The seaweed bed composed of macroalgae serves as a vital biological habitat in the coastal rocky zone and plays an ecological role as coral reefs, mangroves, seagrass beds and salt marshes do. Additionally, it constitutes a significant component of blue carbon. This study exemplified the Hainan Eucheuma Reserve to investigate and evaluate the distribution characteristics and carbon storage capacity of seaweed in this area, while establishing an investigation and evaluation method for Hainan's seaweed bed carbon storage. The results showed that the average coverage of macroalgae in the subtidal zone reached 50%. There were 34 species of macroalgae in 23 genera, and the dominant species were Zonaria diesingiana, Sargassum polycystum etc. The average biomass of marcoalgae was 267.75 g·m⁻². The dry-wet ratio of the collected macroalgae was 11.58%~43.54%, and the organic carbon content was 14.25%~39.19%. As a result, the carbon storage of seaweed in the Hainan Eucheuma Reserve was (2252.77±19.37) Mg C, and average carbon density of seaweed bed was (0.49±0.004) Mg C·hm⁻².

Key words: seaweed bed, carbon storage, blue carbon
