The Loess Plateau is renowned for its deep soil layer and rich in organic carbon (C). In recent years, numerous ecological restoration projects have been undertaken on the Loess Plateau, with consequence on the stability of soil organic carbon (SOC). The SOC stability is pivotal for its capacity to sequestrate and store C. However, comprehensive review on the characteristics of SOC stability and its mechanisms during vegetation restoration on the Loess Plateau is scarce. Therefore, we summarized the dynamics of SOC stability during vegetation restoration on the Loess Plateau, discussed the mechanisms of SOC stabilization, including mineral protection, physical protection, and biological mechanisms. Furthermore, we prospected the future development directions and research focus of SOC stability research during vegetation restoration on the Loess Plateau to provide scientific support for theory and technology of soil C sequestration and stabilization during vegetation restoration, and to provide scientific reference for achieving the "double-carbon" goals.
黄土高原土层深厚，富含有机碳（C）。近年来，黄土高原开展了大量生态恢复项目，对土壤有机碳（SOC）的稳定性产生了影响。SOC 的稳定性对于其固碳和存储 C 的能力至关重要。然而，关于黄土高原植被恢复过程中 SOC 稳定性及其机制的综合综述很少。因此，我们总结了黄土高原植被恢复过程中 SOC 稳定性的动态变化，讨论了 SOC 稳定化的机制，包括矿物保护、物理保护和生物机制。此外，我们展望了未来黄土高原植被恢复过程中 SOC 稳定性研究的发展方向和研究重点，为植被恢复过程中土壤 C 固存和稳定的理论和技术提供科学支持，为实现“双碳”目标提供科学参考。
