This study aims to investigate the distribution of soil erosion and examine its association with slope and land-use types in the Song Cong basin, Thai Nguyen Province, Vietnam. The GIS-based RUSLE model was utilized to estimate the amount of soil loss and ANOVA was used to test whether the differences among slope classes and land use types were significant. The findings showed that the soil erosion value increased dramatically with slope steepness, which suggested that topography was highly positively related to erosion risk. The two-way ANOVA indicates that slope and land-use types had a significant effect on erosion (p < 0.001) with a significant interaction between them. These results could provide technical support for land-use planning and soil conservation measures, which advocate vegetation recovery on hillslopes and slope dependent management to mitigate risk of soil erosion and promote sustainable watershed development.
