摘要: 黄土高原土层深厚,蕴藏着大量的有机碳,近年来黄土高原开展的一系列生态恢复工程改变了土壤有机碳的稳定性。土壤有机碳稳定性决定了土壤固定和储存有机碳的能力,然而,目前尚未系统综述黄土高原植被恢复过程中土壤有机碳稳定性变化特征及其相关机制。鉴于此,本文概括了黄土高原植被恢复过程中土壤有机碳稳定性的变化规律,梳理了土壤有机碳的稳定机制,主要包括矿物保护作用、物理保护作用和生物机制,并对黄土高原植被恢复过程中土壤有机碳稳定性研究未来的发展方向和研究重点进行了展望,以期为黄土高原植被恢复过程中土壤固碳、稳碳理论与技术提供科学支撑,为“双碳”目标的实现提供科学参考。

Abstract: 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.
