图7 传统剥蚀模型与差异剥蚀模型对比 一致剥蚀对表层土中的碎屑组分和自生组分同步运输,差异剥蚀优先将次生黏土组分从整个风化层搬运到地表径流中

Fig.7 Model of bulk erosion and decoupled erosion Bulk erosion removes the detrital and authigenic components in topsoil indifferently. Decoupled erosion preferential removes the water dispersible clay from the whole regolith column to surface runoff by seepage
