本文通过对近几年来新建和规划铁路遥感工程地质勘测实例的分析，归纳了遥感技术在铁路新线勘 测中的作用；分析了加强铁路地质工作，在勘探设计前期系统开展遥感勘测的必要性;提出了铁路新线勘测中 遥感技术的应用模式

The article introduces briefly several actual projects completed in recent years，concerned with the application of remote sensing on planned railway geological surveying，and illustrates the function of applying remote sensing technology. Meanwhile，it points out that in the earlier stage of railway surveying and design，it is necessary to use systematically remote sensing techno logy to investigate engineering geology conditions. Finally，it puts forward the mode of remote sensing application on geological prospecting of planned railw ay li ne.
