摘要
从土壤侵蚀概念的完整定义出发,指出目前关于土壤抗蚀性、抗冲性等概念存在的局限性缺陷。通过回顾以往土壤侵蚀研究存在的方法不一,指标各异,缺乏统一标准以及应用范围有限等问题,提出了开展土壤可蚀性研究需要注意的问题和今后研究应侧重的方向。土壤可蚀性指标不能仅仅是对单一动力和简单侵蚀形式难易程度的度量,而应该是对包括面蚀、沟蚀等土壤侵蚀全过程特性和规律的反映。因此,区域性、综合性的指标体系建立与评估将是土壤可蚀性研究的重要领域之一。
Starting from the comparison among various definitions of soil erosion, this article points out the existing discrepancy in the concepts of soil anti-erodibility, scouring resistance and so on. Based on the review of such issues as difference in research methods and indicators , lack of unified standard and the limitation of application, this article puts forward the research contents to which more attention should be paid and figures out the direction that should be followed. It is also concluded in this article that the indicator of soil erodibility is not only a measurement of single dynamics and simple erodibility, but also an expression of the rules and characteristics of surface and gully erosion on the whole process. Consequently, the establishment and evaluation of regionalized and comprehensive indicator system is an essential field in the research on soil erodibility.
