遥感技术在地质灾害调查、监测和防治中的应用

遥感在地质灾害(滑坡、泥石流)识别方面,较常规方法有明显的优势,并能快速提供大面积地区的位置、分布、范围、规模、类型、发育环境等数据和图件。本文通过多时相、多平台遥感图像解译,了解它们的动态变化及发展趋势,这些信息为工程灾害评价及滑坡、泥石流防治工作提供了全面可靠的依据。 遥感技术在滑坡、泥石流灾害领域中的应用除遥感技术水平外还依赖于滑坡、泥石流信息机制、应用模型的研究及信息系统的支持。

APPLICATION OF REMOTE SENSING TECHNIQUES TO THE STUDY OF GEOLOGICAL DISASTER

Remote Sensing is superior in landslide and debris flow recognition to the conventional method, it yet can gain data and maps of the distribution, scope, type, growing environment etc of landslide and debris flow efficiently in a large scope of area. Through the interpretation of multi-temporal and multi-platform remote sensing images the dynamic characters and developing tendency of landslide and debris flow can also be grasped. Therefore remote sensing can provide overall and reliable basis for landslide and debris flow assesment and prevention.Despite of these great successes, the application of remote sensing in the field of landslide and debris flow in China is still in a primary stage, and there is great potentialities be brought in to play.Apart from the technology of remote sensing itself, the advance of the application level is depend on the study of the mechanism and applying model of landslide and debris flow, and on the support of the disaster information system.
