Abstract: In order to explore the effects of different herbal vegetation on runoff and sediment yield on slope, under artificial simulation rainfall condition, the Annual phlox, Sedum lineare, Festuca glauca are selected to carry out experimental study with a design slope of 10°, and the Bluegrass, Ryegrass, Tall fescue are selected to carry out experimental study with a design slope of 5°, 10°, 15°, respectively.The results showed that different herbal plants could effectively reduce the runoff and sediment yield of soil sediment, and play a role in soil and water conservation and ecological restoration.For the same herb, under different slopes, the greater the slope, the greater the runoff yield, sediment yield and soil erosion, and the greater the action coefficient.
