中文摘要：

线性项目建设跨度大、地貌复杂、所经地区生态类型多样,监测工作难度较大,全面调查几乎是不可能的。该文通过对某输气管道工程陕西段水土保持监测内容、方法与技术手段等方面的阐述,探索抽样调查法在线型工程监测中的积极作用,具有一定的现实意义。监测结果表明：各防治区水土保持措施布局合理,防治效果明显,6项防治目标均达到国家规定的建设类开发建设项目一级防治标准。

英文摘要：

Because of large-span construction,complex topography,different ecosystem types,it is impossible for line-project to be invested and monitored thoroughly.The paper introduced the contents and the technological measures of soil and water conservation monitoring in a gas transfer pipeline project across the Shaanxi section,discussed the active effect of sample survey in line-project monitoring and practical significance.The monitoring results indicated that each prevention area conservation of water and soil measure layout is reasonable,the control efficiency is obvious,six prevention goals meet the national stipulation the construction class development items of basic construction first-level prevention standard.
