本文阐述了土壤有机质(SOM)稳定性的影响因素及其稳定性特征,包括有机物质化学稳定性、物理稳定性和生物化学稳定性,探讨了通过分子特征,即元素组成、功能团、分子构像;有机物、无机物质或其它有机物质之间的分子间相互作用;有机质与微生物和酶之间的作用;以及水热条件对SOM稳定性的影响。
In this paper, the influencing factors and stability characteristics of soil organic matter (SOM) stability are described, including the chemical stability, physical stability and biochemical stability of the organic matter. The effects of molecular structure, molecular structure, molecular structure Like; intermolecular interactions between organic, inorganic or other organic matter; the role of organic matter with microorganisms and enzymes; and the effect of hydrothermal conditions on the stability of SOM.
