Abstract
Gannan is located in the southern red soil hilly region, characterized by concentrated rainfall, interlaced ravines, and poor soil structure, which contribute to severe soil erosion. With rapid economic development, various construction projects have been launched, disrupting the surface and destroying the original landforms, making vegetation restoration extremely difficult. This study takes the Ganzhou Hele Substation as an example, applying “W-OH + soil microbes” to the slopes of the substation, with a control group for comparison. Through soil infiltration tests, soil erodibility modeling, organic matter content analysis, and plant root vitality assessments, the effectiveness of vegetation restoration on erosion-affected land slopes in the Gannan mountainous region under different configuration modes was verified. The results show that the W-OH material significantly reduces water infiltration in the eroded soils of the Gannan mountain area, enhances soil erosion resistance, and the soil microbes effectively increase soil organic matter content and plant root vitality. The combined application of both is complementary. The configurations “soil microbes + 3.0% W-OH” and “soil microbes + 4.0% W-OH” are more beneficial to the rapid restoration of vegetation in the erosion-affected land in the Gannan mountainous region.
