The study looked at how different types of land use affect erosion resistance in calcareous soil in a mountainous area. They found that soil on farmland had the highest clay content, making it more prone to erosion. Shrub land had the best soil stability and water retention. Farmland had the highest erosion rates and poorest soil structure. The soil in the study area had unique characteristics that made it more susceptible to erosion, with differences in permeability between upper and lower soil layers. Overall, the findings suggest that land use plays a significant role in soil erosion in karst mountainous areas.
