摘　　要：西气东输管道工程陕西段全长346.20km,工程建设中扰动破坏原地貌和地表植被,产生大量弃土弃渣。经分析计算,新增土壤流失8.35×105t,其中扰动破坏原地貌新增土壤流失量为6.80×105t,占总流失量的81.41%;弃土弃渣流失量为1.55×105t,占总流失量的18.59%。扰动破坏原地貌造成新增土壤流失是防治的重点,必须采取切实可行的防治措施。The overall length of Shaanxi Province from West-to-East-Natural-Gas-Pipe-Project is 346.2 km. Due to the project construction, vegetation on the original land has been distroyed with a consequence of large quantity of deserted .soil, dregs and remains. According to analysis, newly additional soil erosion amounts to 8 354 000 tons, of which deserted soil is up to 6 800 000 tons, occupying 81.40 percent out of the total volumn, deserted dregs and remains is to up to 1 553000 tons, occupying 18.59 percent of the total. Practical measures are supposed to be taken to controll soil erosion caused by the project constrution.
