摘要 综述了土壤有机质特征、土壤腐殖质化学分组、土壤有机质物理分组,如土壤有机碳的密度分组和土壤有机碳颗粒大小分组,以及气候、时间、母质、植被和草地退化、土地利用变化等因子对土壤有机碳含量的影响,揭示了当前有关土壤有机碳研究进展和发展趋势。 The paper reviewed the research progress on soil organic matter characteristics, chemical fractionation of Soil humus, physical fractionation of soil organic matter such as density fractionation and particle size fractionation and effects of climate, time, texture, vegetation, land degradation and land use change on soil organic carbon content.
