Research Progress on the Effect of Wind Erosion on Soil Physical and Chemical Properties
The effects of wind erosion on soil physical and chemical properties were clarified,and the interaction mechanism between wind erosion and many soil physical and chemical factors was discussed,which provided an important reference for the effective implementation of wind erosion control and soil and water conservation measures.In this paper,several key physical and chemical factors such as soil bulk density,soil water content,soil aggregates,soil particle size composition,soil organic carbon and soil nutrients were reviewed.By combing the dynamic changes of the above indicators in the process of wind erosion,the influence mechanism of wind erosion on soil physical and chemical properties was analyzed,and the shortcomings in this study were revealed.The fu-ture research trends were prospected.The research method is single,and the indoor simulation and field test are not fully combined;the basic process and mechanism of soil quality changes in the existing research is not yet mature.In the research process,indoor simulation experiments should be combined with field experiments and a comprehensive research framework should be constructed;the microscopic migration mechanism of soil particles under the action of wind force was deeply studied and a more accurate soil quality evaluation system was estab-lished;the interaction mechanism between wind erosion and soil physical and chemical properties is clarified,which provides a solid theoretical basis for the further improvement of wind erosion control and soil quality eval-uation systems.
