摘要
土壤团聚体是土壤的重要组成部分 ,影响了土壤的各种物理化学性质 ,对土壤侵蚀有重要影响 ,其水稳性和数量是评价土壤可蚀性的重要评价指标。综述了土壤团聚体的形成、影响土壤团聚体水稳性的因素、以及土壤团聚体研究方法的研究的最新进展 ,针对其中存在问题 ,指出今后可能的发展方向。
Soil aggregate is the main component of soil.It has an important effect on soil physical and chemical characteristics and soil erosion. The quality and quantity of soil water stable aggregates were selected as the main index to assess soil erodibility. Based on reviewing the history and present situation of the study on soil aggregates,the developments in the forming mechanism,the factors influencing water stability and breakdown mechanism were summarized. Finally the main question and future of the research in this field were put forward.
