この研究は、中国南部の河口域と開放海岸におけるマングローブ、海草床、干潟の自然および修復された生態系から90本のコアを分析し、堆積物中の炭素と窒素の蓄積を評価しました。有機物動態モデルと同位体分析を統合し、修復の長期効果は種選択と水文地形条件に依存することを明らかにしました。結果は、ブルーカーボン修復の気候変動対策としての信頼性を高めるためのプロセスベースの基盤を提供します。
English
This study analyzed sediment carbon and nitrogen accumulation in 90 cores from natural and restored mangroves, seagrass beds, and tidal flats in estuarine and open-coast settings in South China. Using an organic matter diagenetic model, multi-decadal dating, and stable-isotope source apportionment, they found that restoration effectiveness depends on species choice and hydrogeomorphic context. The results provide a process-based foundation for improving the climate credibility of blue carbon restoration practice and policy.

In the global GX context
Globally, blue carbon is gaining traction as a nature-based solution, but its credibility hinges on robust carbon accounting. This paper provides a rigorous empirical framework incorporating diagenetic modeling and isotope source apportionment, which can inform IPCC guidelines and national inventories. It underscores the necessity of site-specific restoration strategies to maximize long-term carbon sequestration.

📄 Abstract（原文）
Blue carbon ecosystems contain disproportionately large carbon stocks and have therefore become priority targets for ecological restoration. Yet long-term effectiveness of restoration remains uncertain because species choice and hydrogeomorphic settings are rarely evaluated together in relation to C and N sequestration. Here, we analyzed sediment C and N accumulation in 90 cores from natural and restored mangroves, seagrass beds, and tidal flats across estuarine and open-coast settings in South China, integrating an organic matter diagenetic model, multi-decadal dating, and stable-isotope source apportionment. These results provide a process-based basis for aligning species selection and restoration priorities with local hydrogeomorphic conditions, thereby improving the climate credibility of blue carbon restoration practice and policy.
