摘要
川藏公路地质灾害频繁发生 ,不但给人类生命财产带来严重损失 ,而且严重影响川藏公路的畅通。因此 ,搞清川藏公路的地质状况对川藏公路的设计、维护和灾害治理都十分重要。遥感和地理信息系统的结合能全面宏观地分析研究区的真实现状。利用航空相片和卫星遥感资料 ,通过定标、除噪、几何校正和图像增强等图像处理和解译 ,结合地理信息系统的综合分析技术 。
Geological hazards such as landslides, rockfalls and debris flows happen frequently in Chuanzang Road 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 Chuanzang Road .The real status of Chuanzang Road could be analyzed macroscopically by using remote sensing such as aerial photographs and Landsat TM 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 Landsat TM data combining the technique of geography information system were used to investigate the geology of Chuanzang Road by image geometry correction and image enhancement and spatial analysis. It is predicted that the integrate application of remote sensing (RS) and geographical information systems (GIS) will promote the development of geological investigation.
