[Objective] In order to provide some reliable bases for ecological restoration of quarry slopes, the comprehensive effects of ecological rod method on controlling the soil and water loss on slopes were investigated.[Methods] Large-scale artificial rainfall tests were conducted to collect information about the quantities of runoff and sediment from surface layer and debris flow, and upon which a comprehensive model was built.[Results] With the increase of slope degree, the quantities of runoff and sediment from surface increased while that from debris flow decreased. Total sediment did not change as significant as the total runoff did. The correlation of runoff and sediment from surface layer was higher than that from debris flow. Ecological rod protective measures built on <15°slopes had the highest benefits when rainfall intensities were 30 mm/h and 120 mm/h. Slope degree had little influence on runoff and sediment when rainfall intensity was 60 mm/h.[Conclusion] The ecological rod protective measure has significant effects on the control of soil and water loss by intercepting surface runoff and sediment.
