To explore the relationship between rainfall intensity, gravel coverage and splash erosion amount, we analyzed the effect of different gravel coverages (0, 5%, 10%, 15%, 20%) on the splash erosion under different rainfall intensities (40 mm/ h, 80 mm/ h and 120 mm/ h) through artificial rainfall simulation and using a self鄄made round splash plate. The results showed that at the same gravel coverage, splash erosion amount had a linearly positive correlation with rainfall intensity. Under the same rainfall intensity, splash erosion amount exponentially decreasing with gravel coverage. With the increase of rainfall intensity, the amount of soil splash erosion affected by the gravel coverage would decrease. Soil splash erosion increased first with the increase of splash erosion distance and then decreased. The distance of splashed soil particles was positively correlated to rainfall intensity. Gravel coverage has considerable effects in inhibiting splash erosion.
