Abstract:: In order to meet the inherent needs of high-quality green development of the State Grid Corporation of China, prevent and control the serious soil erosion caused by the construction of the transmission line project, taking loess hilly region and red soil hilly region as a study area, we investigated the variation in natural influencing factors of soil erosion such as climate, topography, soil and vegetation and soil erosion characteristics of transmission line engineering through field investigation and literature review. The results show that: soil erosion force in the loess hilly region includes wind and water, which is different from the red soil hilly region where water erosion dominates; the soils in the loess hilly region have strong permeability and deep layer, while the soils in red soil hilly area are characterized by a heavy texture, poor infiltration capacity and high potential of sealing in water; the natural revegetation in the loess hilly region is limited, which means that replanting is needed during the construction process, while the natural revegetation in the red soil region is strong and the revegetation can be restored naturally shortly after the construction; the soil erosion rate during the construction period of the transmission line project in the loess hilly region was 1～10 times that of the natural recovery period; the soil erosion rate of the transmission lines in the loess hilly area was 2.5～31.25 times that of the red soil hilly area; the erosion rate of the loess hilly area reached the largest value in the converter station area, the motor cable area and the tower base area of the Yulin City; the water and soil loss in the converter station area and the line engineering tower base area was the largest; the erosion rate of the transmission line project in the red soil hilly area reached the maximum in the tower base area in Yichang City, and the newly added soil erosion in the tower base area was also the largest; the tower base area was a key area for soil erosion prevention and monitoring. Therefore, according to the differences of local natural factors, the design of engineering measures in different regions is conducive to reducing soil erosion.
