Abstract: Wind power generation provides clean energy, while brings a certain degree of soil erosion and ecological environment damage. Because of the low resistance to soil erosion and the difficult recovery after vegetation destruction, the soil erosion caused by the development process is particularly prominent in mountain wind farm. This paper reviews studies of soil erosion characteristics of wind farm in mountainous areas and key factors affecting wind farm soil erosion. The soil erosion of wind farm in mountainous area is characterized by geographical incompleteness and disturbance diversity. Road construction area and wind turbine construction area are the key areas of soil erosion. Soil erosion varies in time and space. Soil erosion occurs mainly in the construction period and severe soil erosion occurs mainly in the peak phase of rainfall. Rainfall is the most important factor affecting the soil erosion of wind farm. The stability coefficient of landslide decreases sharply in the precipitation period. The infiltration of precipitation promotes the development of slope deformation and destruction to the unfavorable side, which can easily cause soil erosion and slope instability. The rainfall erosive force index was related to rainfall amount and rainfall intensity. According to the different meteorological data, the rainfall erosive power was estimated by both monthly and daily rainfall. For predicting soil erosion intensity of mountain wind farm, the whole forecast area was divided into 4-6 blocks to determine the soil erosion modulus before, during, and after the construction disturbance in each block.
