[Objective] Studying the influences of vegetation on rainfall infiltration and runoff erosion and sediment yield in order to provide a scientific basis for rationally allocating the vegetation in gravel soil slope in the Three Gorges area.[Methods] Runoff plots containing gravel soil were set with different types and coverage of vegetation. Artificial rainfall experiments were conducted.[Results] The amount of runoff showed as follows bare slope > shrub slope > herb slope > grass shrub mixed slope, in contrast, infiltration and runoff showed the opposite trend. The interflow in vegetation-covered slope was greater than that in the bare slope. Infiltration rate obeyed the law of logarithmic function, while the runoff yield strength varied as power function. The regulation mechanism of grassland to water and sediment was mostly direct sad blocking. The relationship between cumulative runoff and cumulative sediment yield showed as the power function.[Conclusions] Vegetation measures can effectively reduce soil and water loss in gravel soil slope, and different vegetation measures represent the different reducing benefits.
