摘　　要：公路建设具有涉及地貌类型丰富、土石方开挖量大、建设周期长等特点,会导致地表植被遭到破坏及水土流失。干热河谷具有特殊的自然地理条件,因此其公路建设中水土保持具有特殊性。以溪洛渡水电站S307泸盐路南田至坪头段复建公路水土保持植物措施配置为例,结合干热河谷植被恢复技术研究及公路水土流失的特点,从路基、弃渣场、临时工程3个方面探讨干热河谷公路施工中植被恢复的设计,以期为同类型的公路水土保持建设提供借鉴。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 rally 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 $307 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 construetion about soil and water conservation of highway.
