Abstract:【Objective】This study aimed to investigate the impact of different vegetation restoration types on soil pore characteristics in Benggang areas.【Method】Surface soil samples were collected from four vegetation-restored lands (artificial arbor, artificial forest, artificial shrubland, and artificial grassland) in the Benggang erosion area and an unplanted site was selected as the control (eroded land). The pore characteristics of the aggregates (3~5 mm) were visualized and quantified using X-ray microcomputed tomography (μCT) at a voxel resolution of 5.91 μm. Following the imaging, we measured various physical soil hierarchies, including bulk density, aggregate size distribution, and mechanical composition across multiple scales. 【Result】The results indicated that vegetation restoration significantly improved the formation and stability of soil aggregates, leading to notable changes in aggregate pore characteristics and characterized by high anisotropy and fractal dimension. This suggests that different vegetation types not only influence the physical properties of the soil but also enhance its ability to retain water and nutrients, thereby contributing to overall soil structure. The aggregate pore size distribution varied among the different revegetated sites, reflecting the influence of specific environmental conditions and management practices associated with each type of vegetation. The Soil Structure Index (SSI) was used to assess the overall quality of soil structure. The findings revealed that, except for artificial grassland, the SSI values were consistently higher for all vegetation-restored lands compared to the eroded land. The ranking of SSI values followed artificial arbor (0.66) > artificial forest (0.60) > artificial shrubland (0.48) > eroded land (0.31)> artificial grassland (0.25). This hierarchy underscores the significant benefits of arboreal woodlands, particularly citrus orchards, in enhancing soil structure and stability. 【Conclusion】Overall, the results of this study underscore the critical role of vegetation restoration in promoting ecological recovery and improving soil quality in the Benggang erosion areas of South China. By demonstrating the positive impacts of different vegetation types on soil aggregate pore characteristics, this research provides valuable insights for land management and ecological restoration efforts. Future studies could expand on these findings by exploring the long-term effects of various restoration practices on soil health and erosion control, thereby contributing to more effective strategies for sustainable land use and environmental conservation.
