Results showed that the soil erodibility presented highly significant negative correlations with clay particles, soil fractal dimension, and STP ( p < 0.01); significantly positive correlation with sand particles ( p < 0.05); and significantly negative correlations with silt particles, STN, and SOM ( p < 0.05).
However, in the CK plot, the fine particle content in soil showed a decreasing trend from the upper slope to the middle and lower slopes, where the fine particle content in the soil on the upper slope was 23.88%, which was 2.27 and 3.6% higher than those on the middle and lower slopes, respectively.
Therefore, the fine particle (silt and clay particles) content in the soil of each hedgerow plot showed an increasing trend from the upper slope to the lower slope, but the amplitude of increase varied from plot to plot, which was consistent with previous study results.
