摘要
土壤团聚体是土壤结构的基本单元,其稳定性是影响土壤侵蚀的重要因素之一。综述与土壤团聚体稳定性相关的土壤团聚机制、侵蚀过程中的破坏机制以及影响团聚体稳定性的土壤化学性质。这些土壤性质主要有:土壤有机质、铁铝氧化物、交换性钠及土壤矿物学性质等。
Soil aggregate is the basic unit of soil structure, and its stability is one of the important factors to influence soil erosion. Based on reviewing the history and present situation of the study on soil aggregates, the developments in forming mechanism, the chemical factors influencing aggregate stability and the breakdown mechanism were summarized. The main chemical factors include organic matter, sesquioxides, exchangeable Na and mineralogical properties.
