摘　　要：川藏公路作为内地通往西藏的两条公路之一和拉萨通往藏东南地区唯一的交通干线,对于改善西藏投资环境,发展藏东经济,实施西部大开发战略,巩固国防,加强民族团结都具有极其重要的意义。川藏公路道路灾害频繁发生,严重影响公路的畅通。查清川藏公路的道路病害状况对公路的改建、扩建、维护和灾害治理都十分重要。综合利多源、用多时相、多分辨率卫星遥感资料、航空相片资料及以前相关的研究成果,结合地理信息系统的综合分析技术,对川藏公路西藏境内段的道路病害进行了研究。Geological hazards such as landslides,rockfalls and debris flows happen frequently in Sichuan-Tibet Highway and bring about great damage to peoples' life and property.How to make clear the geological status is important to the design and maintenance and disaster's father of Sichuan-Tibet Highway.The real status of Sichuan-Tibet Highway could be analyzed macroscopically by using remote sensing such as aerial photographs and CBERS data.As a powerful tool for spatial analysis and spatial database management,geographical information systems(GIS) are drawing more and more attention in the field of the geological investigation.In this paper,the aerial photographs and CBERS data combining the technique of geography information system were used to investigate the geology of Sichuan-Tibet Highway by image geometry correction and image enhancement and spatial analysis.The results shows there are 324 debris flows,81 landslides and 367 rockfalls.It is predicted that the integrate application of remote sensing(RS) and geographical information systems(GIS) will promote the development of geological investigation.
