植被恢复的土壤固碳效应：动态与驱动机制

植被恢复是影响土壤有机碳库动态变化的关键过程之一，阐明植被恢复过程中土壤有机碳的固持动态及其驱动机制，是全球变化下碳循环研究的热点和前沿问题。本文综述了近年来国内外关于植被恢复过程中土壤有机碳固定动态及其驱动机制方面的研究，剖析植被恢复中土壤有机碳固持动态及其影响因素，探讨植物碳输入对土壤有机碳动态变化的影响机制，揭示植被恢复中土壤有机碳固定的物理、化学和微生物驱动机制，并对目前研究中存在的问题进行总结，进而提出关于植被恢复的土壤固碳效应研究，亟需在土壤有机碳组分的动态、微生物结构和功能，以及植物—土壤—微生物对土壤有机碳固持的协同作用机制等方面进一步加强。本综述可为植被恢复与土壤固碳稳定机制研究指明未来的方向，进而为促进我国植被恢复的土壤碳循环研究，科学评价生态系统土壤固碳潜力和有效实施生态系统碳汇管理提供科学参考。

Effect of Vegetation Restoration on Soil Carbon Sequestration: Dynamics and Its Driving Mechanisms

Vegetation restoration is one of the key processes affecting the dynamic change of soil organic carbon pool.To elucidate the soil organic carbon sequestration dynamics and its driving mechanism in the process of vegetation restoration is a hot and frontier issue in the study of carbon cycle under global change.This paper reviewed the published studies on the dynamics of soil organic carbon sequestrations in the process of vegetation restoration and its driving mechanism in recent years at home and abroad,analyzed the dynamic of soil organic carbon sequestration and its influencing factors in vegetation restoration,explored the influencing mechanism of plant carbon input on the dynamics change of soil organic carbon,and revealed the physical,chemical and microbial driving mechanisms of soil organic carbon sequestration in vegetation restoration.Furthermore,the review summarized the problems existing in the current research,and then the urgent research on soil organic carbon sequestration during the vegetation restoration process in the future was proposed to further strengthen the aspects of soil organic carbon component dynamics,microbial structure and function,and the synergistic mechanism of plant-soil-microorganism on soil organic carbon sequestration.This review can point out the future direction for the study of vegetation restoration and soil carbon sequestration stabilization mechanism,and then provide scientific reference for promoting soil carbon cycle of vegetation restoration,scientific evaluating the potential of soil carbon sequestration and effective implementing measures in ecosystem carbon sink management.
