摘要: 土壤团聚体是土壤结构的基本单元,对改善土壤结构和增加土壤固碳具有重要作用。盐渍化导致的特殊土壤性质,如高盐分离子(主要为Na+)浓度、低有机质含量和较差的微生物条件等因素,对团聚体的形成和稳定产生障碍作用,因此探讨盐渍化土壤团聚体特征更具有重要性和特殊性。滨海湿地和内陆盐渍化沼泽湿地是盐渍化生态系统的重要组成部分。本文系统整理和总结了国内外盐渍化土壤团聚体及其有机碳的研究进展,并对上述两种盐渍化湿地生态系统中土壤团聚体研究进行了综述。土壤有机无机改良剂添加、耕作方式、植被类型、秸秆还田以及微咸水灌溉等农业措施对盐渍化土壤团聚体及其有机碳形成和稳定具有积极影响。最后提出了目前盐渍化土壤团聚体及其有机碳研究存在的问题和不足,并对未来的研究方向和热点进行了展望,为全面了解盐渍化土壤团聚体研究的最新成果和发展方向提供参考。

Abstract: Soil aggregate, as a basic component of soils, plays an important role in improving soil structure and enhancing soil organic carbon (SOC) sequestration. The special soil properties induced by salinization, such as high ion concentrations (mainly Na+), shortage of organic material and bad condition of microbe, inhibit the formation and stability of soil aggregate. Therefore, it is important and meaningful to explore the dynamics of aggregate in salinized soils. Coastal wetland and inland salinized marsh wetland are important salinized ecosystems. We systematically summarized the progress and achievements on soil aggregate in salinized agriculture and wetland ecosystems. Agricultural practices, such as organic and/or inorganic soil amendment application, tillage practice, vegetation type, straw return and saline water irrigation, advance the formation and stability of aggregate and aggregate-associated organic carbon in salinized soils. We discussed the problems and deficiency in the present studies of aggregate and aggregate-associated carbon in salinized soils as well as the research aspects and hot topics in the future. This review would be helpful for comprehensively understanding the advances and development directions on aggregate in salinized soils.
