高速公路建设过程中大规模地改变地形地貌、扰乱土壤结构、破坏自然植被，极易引起 水土流失等生态问题。为有效控制因高速公路建设造成的水土流失，快速恢复和重建水土保持 设施，预防水土流失危害，以新疆G314 线库尔勒至库车段高速公路为研究对象，在分析水土 流失影响因素及其特点的基础上，综合考虑主体工程中兼有水土保持功能的工程措施、植物措 施与新增水土保持措施的互补关系，确定了水土保持措施总体布局，并提出了分区防护的具体 措施。研究结果有助于补充和完善新疆高速公路水土保持措施体系，也可为该区同类工程建设 提供科学参考。

Expressway construction inevitably changes topography and landform on a large scale, dis⁃ turbs the soil structure and damages natural vegetation, which easily causes soil erosion and ecological problems. For the purpose of actualizing soil and water conservation effectively in expressway construc⁃ tion, the G314 Korla-Kuqa Expressway in Xinjiang was selected to research the influence factors of the soil and water loss and characteristics. Considering comprehensively the relationship of engineering mea⁃ sures, vegetation measures and new soil and water conservation measures, which have both soil and wa⁃ ter conservation function, the overall layout of the soil and water conservation measures were deter⁃ mined, and specific measures of division protection were proposed. The results not only help to comple⁃ ment and complete the system of soil and water conservation measures of expressway in Xinjiang, but al⁃ so provide scientific reference for similar construction projects in the area.
