中文摘要：

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／cm2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／cm。时，土壤的抗蚀性随着土壤密度的增大而减小。

英文摘要：

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.
