中文摘要	以临河至策克铁路为研究对象，选择土壤、地貌、植被类型作为沙漠化敏感性评价因子，根据TM遥感影像，参考铁路沿线有关资料，并结合现场调查，编制了铁路沿线地貌、土壤和植被图。采用图层权重一级别打分叠加模型，对铁路沿线土地沙漠化敏感性进行评价。结果表明，临策铁路大部分位于沙漠化高度敏感区，占全线长度的54．5％；极度敏感区占4．4％。这些区域也是风沙流主要分布地区，在铁路工程施工期及运营期应该采取有效保护措施，防止沙漠化土地的扩大与蔓延以及风沙流的加剧。
英文摘要	The Linhe-Ceke Railway was cited as subject in a case study, and soil, landform and vegetation type are selected as key factor in assessing land sensitivity to desertification. Based on remote sensing images and data related to the two sides along the Linhe-Ceke Railway, landform, soil and vegetation maps are plotted. Sensitivity of the land to desertification alongside the railway was evaluated, using the weighing-grading map superposition model. Results show that 54. 5% of the two land strips alongside the whole length of railway is highly sensitive and 4.4% extremely sensitive. The two parts are the major zone distributed with drifting sands. Effective measures should be taken in the areas during the construction and operation periods so as to prevent land desertification and drifting sands from extending and aggravating.
