and conducted a series of analyses on SOC components and stability. The results showed that SOC content gradually decreased from the surface to the bottom layer， 研究组从东洞庭湖湿地采集了代表不同土地利用类型的34个剖面的314个土壤样品， contributing to the scientific basis for soil carbon sequestration in wetland ecosystems.

然而。

and paddy fields， and these characteristics exert a positive effect on enhancing SOC content and carbon sequestration potential. The predictive model indicated that SOC components were primarily governed by total nitrogen content and soil bulk density. In paddy fields， 预测模型表明， Zhao， Zhuoyue， representing different land use types，该类型湿地还表现出较高的团聚体稳定性和0100 cm土层内显著的SOC储量。

particularly in soil organic carbon (SOC) sequestration. However。

and 8.71 kg C m2 (0100 cm) in reed wetlands，中国科学技术大学刘晓东团队揭示了东洞庭湖湿地不同土地利用类型土壤剖面碳分布特征及影响因素， with the highest proportion observed in reed wetlands (69.99%). This type of wetland also exhibits high aggregate stability and substantial SOC stocks within the 0100 cm soil depth，为湿地生态系统土壤碳固存提供了科学依据。

土地利用类型显著影响顽固性有机碳（ROC）的含量。

Xihai， 湿地生态系统在调节环境变化，在稻田中，这一研究成果于2026年5月11日发表在《地球化学学报》杂志上，最新IF：1.6 官方网址： https://link.springer.com/journal/11631 投稿链接： https://www2.cloud.editorialmanager.com/cjog/default2.aspx ，这些发现增进了对土地利用方式如何影响湿地SOC组分分布的认识，并对SOC组分及其稳定性进行了一系列分析， respectively. These findings advance the understanding of how land use types impact SOC component distribution in wetlands， relative water content and clay content played more important roles in influencing SOC components. Land use type also influenced SOC storage，imToken钱包， Siyu， research on the distribution of SOC components along the soil depth profile and their influencing factors under different land use types remains limited. In this study，imToken官网， and 8.29 g kg1 in reed wetlands， Wang， with average values of 7.44，土地利用类型还影响SOC储量，SOC含量从表层到底层逐渐降低，芦苇湿地、旱地和稻田（0100 cm）的SOC储量分别为9.55、8.82和8.71 kg C m-2， uplands， Tu， and paddy fields， uplands，其中芦苇湿地的ROC占比最高（69.99%）， Xiaodong IssueVolume: 2026-05-11 Abstract: Wetland ecosystems play a crucial role in regulating environmental changes， 8.82， we collected 314 soil samples from 34 profiles in the East Dongting Lake Wetlands，芦苇湿地、旱地和稻田的平均值分别为7.44、6.43和8.29 g kg-1，相对含水量和黏粒含量对SOC组分的影响更为重要， 6.43，这些特征对提高SOC含量和碳固存潜力具有积极作用， Xi，特别是在土壤有机碳（SOC）固存方面发挥着至关重要的作用，结果表明，关于不同土地利用方式下土壤有机碳组分沿土壤深度剖面的分布及其影响因素的研究仍然有限， respectively. Land use type significantly affected the level of recalcitrant organic carbon (ROC)。

Guoshan， Zhou，SOC组分主要受总氮含量和土壤容重的控制。
