本レビューは、バイオ炭が微生物炭素ポンプ（MCP）と鉱物炭素ポンプ（MnCP）を連携させる「橋渡し」役を果たすメカニズムを統合的に解説。バイオ炭は難分解性炭素源としてだけでなく、微生物の生息環境を提供し、有機物－鉱物複合体の形成や微団粒構造の促進により炭素を安定化する。将来の研究では、メカニズムの解明やライフサイクル評価への組み込みが重要と指摘。
English
This review positions biochar as a critical 'bridge' between microbial and mineral carbon pumps for synergistic soil carbon sequestration. Biochar not only provides recalcitrant carbon but also enhances microbial habitats and forms stable organo-mineral complexes, improving carbon stabilization. Future research should focus on mechanistic dissection and integrating biochar's dual pump effects into life cycle assessment.

📄 Abstract（原文）
Enhancing soil carbon sequestration is a pivotal strategy for mitigating global climate change. Integrating the "microbial carbon pump (MCP)" and "mineral carbon pump (MnCP)" frameworks is essential for a holistic understanding of soil organic carbon (SOC) stabilization. While biochar (BC) is a recognized carbon sequestration tool, the mechanistic pathways by which it mediates the synergy between these distinct carbon pumps remain elusive. This review synthesizes current advances to position BC as a critical "bridge" driving the coupled MCP-MnCP system. Beyond serving as recalcitrant carbon, BC strengthens the MCP by providing microbial habitats, optimizing community structure, and enhancing carbon use efficiency to promote necromass accumulation. Simultaneously, BC fortifies the MnCP via mechanisms including the formation of stable organo-mineral complexes through surface functional groups, the facilitation of microaggregate genesis, and the mediation of redox reactions. This bridging efficacy offers a novel theoretical framework for developing predictable, controllable soil carbon technologies. Furthermore, we explore the theoretical basis for integrating BC into the coupled MCP-MnCP system. Future research must prioritize cross-scale mechanistic dissection, advance the precision design of BC functionality, and incorporate its "dual carbon pump" enhancement effects into life cycle assessment frameworks to fully realize its potential in climate mitigation and sustainable agriculture.
