Soil anti-scouribility and anti-erodibility were measured by undisturbed soil washing flume method and static water disintegration method. The gap and canopy stand of Picea koraiensis-Abies nephrolepis-Pinus koraiensis forest (PA) and Tilia amurensis-Pinus koraiensis forest (TP) were taken as contrasts to analyze the effects of different pit and mound microsites formed by uprooted trees and soil properties on soil anti-scouribility and anti-erodibility in Xiaoxing'an Mountains, and reveal the relationship between them. The results showed that in the pit and mound microsites of the two forests, the soil sand content was higher and the soil erosion resistance was weaker, but the trends were opposite in the contrast. There was no significant negative correlation between soil bulk density and soil anti-scouribility and anti-erodibility (P>0.05) in the two types of microsite of the two forests, while there was no significant positive correlation between soil bulk density and soil anti-scouribility and anti-erodibility in the gap of the PA (P>0.05). In the TP, the soil bulk density was extremely significantly positively correlated with soil anti-scouribility and anti-erodibility in the gap, while in the canopy stand, the soil bulk density was extremely significantly negatively correlated with them (P<0.01). There was no significant positive correlation between soil organic matter and soil erosion resistance in the two types of microsite, but there was an extremely significant positive correlation between them in the contrast stand. Soil erosion resistance varied with forest types and microsite types, the soil erosion resistance of TP pit and mound microsites was not significantly higher than that of PA. But the soil erosion resistance of PA contrast was significantly higher than that of TP contrast. It can be concluded that the formation ofpit and mound microsites would lead a significant decline in soil erosion resistance, resulting in the loss of soil nutrients, the reduction of soil clay content, and the process of soil restoration was difficult.
