| 摘 要： | 精伊霍铁路所经地区地处西部干旱内陆，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壤侵蚀现象。利用遥感与地理信息系统技术，结合野外调查分析结果，编制了精伊霍铁路两侧30k。范围土壤侵蚀现状图。根据铁路沿线土地退化现状和工程建设活动对地表生态系统的影响分析，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，据此分析了工程可能造成的土地退化危害，并就此提出了相应的防治措施。

| Abstract: | The area,where the Jinghe-Yili-Huoerguosi Railway will pass across,is the western region with 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 range of 30 kilometers 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 land degradation 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 from land degradation was also analyzed,and then the corresponding prevention and cure measurements were put forward. |
