摘要
In order to understand the process of surface erosion and its changing characteristics, a sprinkling experiment is conducted on a bare slope in Mt. Tanakami. Based on the measurements and analysis of runoff, mean soil erosion depth sediment yield and semiment transport, etc., the characteristics in the process of surface erosion in the experimental area are as follows: the occurrence of sediment discharge is interrupted, with a saturated overland-flow surface runoff; the mean erosion depth is 0.086 2 cm, which is thicker compared with other areas in Mt. Tanakmi; sediment yield is 431. 283 m3路km−2, whose process is detachment-limited, and the type of sediment transport is a sediment flow.
