摘　　要：国道214线西藏境位于西藏东南部,连接青海省和云南省,是西藏东南部地区重要的交通干线,该公路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。该路段地形地貌复杂,构造发育,地质灾害频发,严重影响公路的畅通。利用ETM遥感影像,结合已有研究资料和野外调查等手段,对国道214线西藏境的崩塌和滑坡进行研究,并对这些地质灾害的发育状况和危害特征进行了评价。The Tibet part of National Highway 214 locates in South-eastern part of Tibet.Geological hazards such as landslides and rockfalls happen frequently in this highway and bring about great damage to peoples' life and property.To make clear the geological status is important to the design and maintenance of National Highway 214.The ETM data combining the historical data and the investigation of field were used to study the landslides and rockfalls of the Tibet part of National Highway 214 by image geometry correction and image enhancement and spatial analysis.The results shows there are 76 places of rockfalls and 26 places of landslides along the highway.The developing state and harm characteristics of these geological hazards have been evaluated.
