| The characteristics of highway construction, such as rich lands types, a large number of debris excavation, long
construction period, vegetation destruction and slope excavation, have serious problems of soil and water loss. Dry-hot vally regions have special features in geography, hydrology and climatic conditions. Therefore, appropriate plants design should be proposed, when the vegetation measures for soil and water conservation design is carried out. The study set the example of rebuilding the S307 Luyan Road from Nanping to Pingtou in Xiluodu hydropower station vegetation measures of soil and water conservation. Combining the technology of vegetation restoration with the characteristics of highway soil erosion, we discussed the vegetation measures for soil and water conservation in three parts, roadbed, slag yard and temporary works, to provide references for the same type construction about soil and water conservation of highway. |
