摘要
系统梳理了农田盐渍化对土壤有机碳影响的国内外研究进展,重点分析了盐分类型与空间异质性对团聚体结构和有机质保护的影响、微生物多样性及关键功能基因对土壤有机碳转化的调控机制,以及生物有机改良、理化调控及综合耕作管理等措施在土壤有机碳稳定性提升中的作用。基于此,提出明确盐分类型,倡导多组学、分区域和跨尺度等手段协同应用,为提升盐渍化农田碳汇功能和实现可持续治理提供理论与实践支撑。
This review systematically summarizes the progress of domestic and international research on the effects of farmland salinization on soil organic carbon(SOC).It focuses on analyzing the effects of salt types and spatial heterogeneity on aggregate structure and organic matter protection,the regulatory mechanisms of microbial diversity and key functional genes on soil organic carbon transformation,and the roles of bio-organic amendment,physicochemical regulation,and integrated tillage management in enhancing SOC stability.Based on these insights,clarifying salt types and advocating the collaborative application of multi-omics,regional and cross-scale approaches are proposed to provide theoretical and practical support for enhancing the carbon sink function of salinized farmland and achieving sustainable governance.
