摘要

为探究土壤风蚀过程中土壤抗剪强度的变化，以河北坝上干扰破坏地表及未干扰破坏地表的典型翻耕农田为研究对象，采用土壤抗剪强度野外原位直剪试验测定了土壤抗剪强度在风蚀事件前后及风蚀季的变化，结合室内试验分析了土壤抗剪强度与土壤干团聚体粒度的关系。结果表明：未受到干扰破坏及受到干扰破坏2种类型农田地表土壤抗剪切强度与作用在土壤表面的法向应力呈正相关关系，土壤抗剪强度随法向应力的增大而增大；土壤抗剪强度变化与风蚀事件的发生密切相关，除2021年4月27，28日风蚀事件后表层土壤受含水率影响外，其余2次风蚀事件后土壤抗剪强度均发生明显增大，整个风蚀季的土壤抗剪强度变化也呈现出先增大再减小最后略增大的趋势；在风蚀过程中，受到干扰破坏农田地表对于土壤风蚀过程的响应更为敏感，其抗剪强度变化较未受干扰破坏地表抗剪强度变化更为剧烈；土壤抗剪强度随土壤干团聚体平均重量直径增大而增大。为减少坝上地区风蚀的危害，应合理采用保护性耕作措施，在风蚀季减少对农田表层的干扰。

Abstract

In order to explore the changes in soil shear strength during soil wind erosion

typical ploughed farmland on the disturbed and undisturbed surfaces of the Bashang Plateau in Hebei Province was used as theresearch object. The changes of soil shear strength before and after wind erosion events and wind erosion seasons were measured by in-situ direct test

and the relationship between soil shear strength and particle size of soil dry aggregate was also analyzed in conjunction with laboratory experiments. The results showed that the shear strength of undisturbed and disturbed surface soil was positively related to the normal stress acting on the soil surface

and the soil shear strength increased with the increasing of the normal stress. The change of shear strength was closely related to the occurrence of the wind erosion events

and a significant increase in shear strength occurred after the wind erosion event in both cases

except for the surface soil after the wind erosion event on April 27 and 28

2021

which was influenced by the water content. The change of shear strength throughout the wind erosion season also showed a trend of firstincreasing

then decreasing and finally slightly increasing. In the process of wind erosion

the surface of disturbed farmland was more sensitive and its shear strength changed more sharply than that of undisturbed farmland surface. The soil shear strength increased with the increasing of mean weight diameter (MWD) of soil dry aggregate. In order to reduce the damage of wind erosion in Bashang plateau

conservation tillage measures should be reasonably applied

the interference to farmland surface should be reduced during the wind erosion season.
