To explore the effects of different treatment modes on soil erosion resistance in eroded degraded land of granite red soil, field investigation and laboratory experiment were conducted. Soil of five treatment modes in Changting county, including banned (M1), arbor-shrub-grass mixed forest (M2), whole slope grass sowing (M3), low efficiency forest transformation (M4) and the furrow grass shrub zone (M5), were taken as the research objects, clearage (CK1) and the bare land (CK2) were selected as the control. The main influencing factors of soil erosion resistance were revealed by principal component analysis, and the comprehensive evaluation of soil erosion resistance was carried out by combining grey correlation analysis and coupling analysis. The results showed that: (1) The order of soil erosion resistance under different treatment modes was M5 > M2 > M3 > M4 > M1 > CK2 > CK1. (2) The content of water-stable aggregate > 0.25 mm and organic matter content were the main factors affected soil erosion resistance. (3) The soil erosion resistance index was strongly correlated with the soil physical and chemical properties (0.696), and the coupling degree between soil erosion resistance and soil physical and chemical properties of M3 was the highest (0.883). The results provide a scientific basis for soil and water loss control and ecological restoration in eroded degraded land of granite red soil areas.
