To establish a predicting model of slope erosion modulus and gully erosion modulus on the basis of special definition for the meanings of slope erosion, gully erosion and gully gravity erosion.
The change of ephemeral gully headward erosion, gully-wall collapsing and deep-cutting erosion were quantified in the three stages of initial-phase, metaphase and anaphase.
阐明了在浅沟发育初期、中期和后期三个发育阶段，沟头溯源侵蚀、沟壁扩展和沟床下切侵蚀变化规律。
