中文摘要	敦煌铁路所经地区地处荒漠内陆,以沙漠戈壁地貌为主,生态环境恶劣、脆弱,对人类扰动极其敏感.敦煌铁路的建设必将在一定程度上加剧沿线地区的土地荒漠化现象.本文利用遥感与地理信息系统技术,结合野外调查分析结果,编制了柳沟至敦煌段铁路两侧10km范围土壤侵蚀现状图.根据铁路沿线荒漠化现状和工程建设活动对土地荒漠化的影响分析,对施工期土壤侵蚀类型与强度的变化以及工程造成的水土流失总量进行了预测,并据此分析了工程可能造成的土地荒漠化危害,并就此提出了相应的防治措施.
英文摘要	The area, where the railway will be built, is the region with the main physiognomies of desert and Gobi, and the most fragile ecological environment, and is also one of the regions with the high susceptive to man - made disturbance. The construction of the railway will intensify soil erosion along the railway line to a certain degree. The map of soil erosion condition in the section from Liugou to Dunhuang City in the range of 10 kilometers in each side along the line was drawn by using the techniques of remote sensing and geographic information system ( GIS) . Based on analysis of the status of desertification and the influence of the railway construction projects, the changes of the types, intensities and the total amount of the soil erosion caused by the construction were predicted, and the impacts of desertification was also analyzed, and then the corresponding controlling measurements were put forward.
