侵蚀破坏土壤团聚体结构,使团聚体破碎产生更小的可迁移颗粒而导致土壤养分的运移;侵蚀还改变了土壤的水分状况,水蚀在一定程度上增加了土壤的含水量,风蚀则可使土壤的含水量降低。团聚体结构的破坏以及土壤水分状况的改变与土壤的氮素迁移转化过程有着密切的联系。本文仅对土壤侵蚀造成的土壤物理性状的改变与土壤氮素迁移转化作一概述,并就耕作、覆盖等降低土壤侵蚀的农业措施与土壤氮素转化的关系进行阐述,提出了侵蚀土壤氮素研究的去向。
Erosion destroys the structure of soil aggregates and causes the aggregates to break up to produce smaller migratory particles that lead to the transport of soil nutrients. Erosion also changes the soil moisture conditions, which increase soil moisture content to a certain degree, and wind erosion can So that the soil moisture content decreased. The destruction of aggregate structure and the change of soil water status are closely related to the process of soil nitrogen transport and transformation. In this paper, only the change of soil physical properties caused by soil erosion and the transformation and transformation of soil nitrogen are summarized. The relationship between agricultural practices such as tillage and soil cover and soil nitrogen transformation is discussed. The whereabouts of the research.
