摘要
通过研究不同密度土壤的抗冲性、抗蚀性及抗剪强度,探索密度与土壤抗侵蚀性之间的相关关系,并进一步分析密度对土壤抗侵蚀性影响的机理。研究表明,随着土壤密度的增大,土壤的抗冲性与抗剪强度增强;但在土壤密度小于1.27g/cm3时,土壤的抗蚀性随着土壤密度的增大而增加,当土壤密度大于1.27g/cm3时,土壤的抗蚀性随着土壤密度的增大而减小。
In this study, the correlation between the soil density and soil erosion resistance was explored by researching the anti-scouring ability, the soil anti erodibility and the soil sheer strength. The results showed that soil anti-scouring ability and soil sheer strength were enhanced with the increase of soil densi- ty; but the soil anti erodibility was not same. When the soil density was lower than 1.27 g/cm3 , the soil anti erodibility was enhanced with the increase of soil density, otherwise it decreased with the increase of soil density.
