Aiming at the technical difficulties such as the stability and water balance in the ecological rehabilitation of river flinty slope, a gravel mulch technology was proposed, with the effects of different gravel mulch treatments on the soil anti-erosion capacity, soil water retention property, and plant growth investigated by anti-erosion and pot experiments. The results showed that mulching with the gravels 1. 5-2 cm in size could obviously enhance the soil anti-erosion capacity, soil water retention property and plant biomass, but no obviou.s differences were observed between the mulch thickness of 5 cm and 8 cm. It was indicated that mulching with the gravels 1. 5-2 cm in size and 5 cm in thickness was an effective and economical technology for the ecological rehabilitation of river flinty slope.
