摘要： 沙地生态系统在全球碳循环过程中至关重要，其内部的碳循环机制对于维持全球碳平衡具有关键作用。土壤有机碳（Soil organic carbon，SOC）作为该系统的核心要素，不仅影响土壤有机物质的循环与更新速率，还关联沙地生态系统功能状态的变迁，是衡量该系统健康与稳定性变化的关键指标。为深入理解沙地 SOC 及其稳定性特征，从 Web of Science 和中国知网（CNKI）数据库中整理 1998—2024 年间全球沙地有机碳相关文献并基于文献进行分析，结果表明： （1）1998—2024 年，沙地 SOC 相关研究发文数量呈增加趋势，国内研究热点为“土壤养分”“沙漠化”等，国际研究热点为“氮”“碳”“土地利用”等。（2）沙地 SOC 含量、储量及其组分受土地利用方式、微生物活性、植被类型及人类活动等多种因素的影响。（3）沙地有机碳稳定性是物理保护、化学保护、生物保护共同作用的结果，物理保护（如团聚体）为化学保护（如矿物吸附）提供微观环境，生物保护（如微生物活动）通过分泌胶结物质促进团聚体形成。未来需融合多种现代科技手段，实现空间联网的长期定位观测，因地制宜地开发和应用土壤碳增汇技术模式，以期全面揭示沙地 SOC 的影响因素以及稳定机制，为实现沙地生态环境的可持续固碳目标奠定基础。
