[Objective] The rainfall characteristics and water and sediment control ability of different types of artificial forestland in an exposed feldspathic sandstone area were determined in order to provide guidance for vegetation construction in the study area and for sediment reduction into the Yellow River.[Methods] The annual natural rainfall and soil erosion of plots on Pinus tabulaeformis, Apricot, Hippophae rhamnoides, and Caragana korshinskii plantations, and on grassland and bare land were monitored by means of runoff plot monitoring.[Results] ① Under the condition of long duration heavy rain and moderate to heavy rain in an exposed feldspathic sandstone area, instantaneous rainfall presented a double peak trend, and cumulative rainfall increased in a ladder pattern. The short duration rainstorm and the instantaneous rainfall of a light to moderate rain showed a single peak trend, and the cumulative rainfall showed an S shape and a linear increasing trend, respectively. ② The erosion of exposed bedrock slopes was serious, with a total runoff of 28.48 L and a total soil erosion of 31.85 t/(hm²·a). The total runoff of vegetation slopes was between 9.8 and 18.41 L, and the total soil erosion was between 1.67 and 10.14 t/(hm²·g). There was no uniform rule for the yield and discharge for different types of artificial forestland with change in rainfall type. However, the amount of soil erosion followed the order of bare land > grassland > Caragana korshinskii > Apricot > Pinus tabulaeformis slightly > Hippophae rhamnoides forests. The yield and discharge of Pinus tabulaeformis forest and Hippophae rhamnoides forest were significantly correlated with soil erosion, with correlation coefficients of 0.929 and 0.893, respectively. The mean rainfall intensity and I₃₀ were significantly correlated with soil erosion, and the correlation coefficients were greater than 0.595. ③ The relationship between rainfall and erosion of different types of artificial forestland conformed to a multiple linear equation (R²>0.771). The Nse of the rainfall and runoff model was greater than 0.62. The Nse of the rainfall and sediment production model was greater higher than 0.57, except for the Caragana korshinskii plantation. It showed that the model accuracy was relatively high.[Conclusion] Under erosive rainfall conditions in a bare feldspathic sandstone area there is a certain functional relationship between rainfall, runoff, and sand production in forest plantation land, and the erosion on forest plantation land is smaller than on bare slope.
