For developed eluvial horizon (A), illuvial horizon (B), transition horizon (BC) and the parent material horizon (C) of granite collapsing gullies region in Tongcheng, Hubei province, the impact of slope and flow on soil anti–scouribility and related soil physical properties were explored. Specifically, the slope were 8.8％, 17.6％, 26.8％, 36.4％, and 46.6％, and the flow were 0.2 L/s, and 1.0 L/s, respectively. The results showed that physical and chemical properties were ⑴ significant different among layer A, layer B, layer BC, and layer C of granite collapsing gully soil. ⑵ When the flow was constant, index of soil anti-scourability showed a decreasing trend, with the increase of the slope; when the slope was constant, the index under high flow conditions was low; at the same slope and flow conditions, the index decreased from layer A to layer C, indicating that layer A has the best anti-scourability, while layer C has the worst. ⑶ The soil anti-scourability index of all layer decreased linearly with the increase of the slope (p<0.05), and the erosion resistance of soil decreased with the increase of the slope. The absolute values of the coefficients of regression equation in layer A were the largest and the constant was also the largest. This shows that theanti-scourability of layer Achanges sharply with the slope, the erosion resistance of layer A is the strongest and the soil loss is the least. ⑷ There was a positive correlation between soil anti-scourability index and the content of silt, clay content, water stability index and permeability coefficient, and negative correlation with soil dry density and sand content. The correlation between dry density and water stability index was very high, which showed extremely significant correlation. The soil anti-scourability was positively correlated with organic matter content, CEC and free iron Oxide, while negatively correlated with soil pH, specifically, the correlation coefficient with the organic matter content was greater than 0.9, which was extremely significant.
