The characteristics of natural environment and soil and water loss along the Hechi-Baise section of Shantou-Kunming Expressway are briefly described. According to the layout of the project and the construction characteristics of the project, the project area is divided into subgrade, interchange, bridge, tunnel, facilities along the line, Spoil grounds, temporary landfills, construction access roads and 10 production and living areas of the construction area for soil erosion prediction. According to the characteristics of the project located in the mountainous area, the terrain is undulating and the high slope is large, according to the different prevention and control zoning Soil and water loss, in accordance with the key governance and the level of prevention and control, the combination of engineering measures and plant measures, the combination of permanent measures and interim measures to determine the principle of prevention and treatment in all districts and the allocation of measures.
