中国滑坡遥感

我国滑坡遥感已有20多a的历史,作为区域性滑坡宏观调查的主要手段曾为山区大型工程建设的滑坡灾害调查及防灾减灾工作 作出了重要贡献。上世纪末以来,由于采用了“数字滑坡技术”和高分辨率遥感数据,滑坡遥感成为能更准确的定性、定量的调查手 段,甚至可进行大型个体滑坡的详细调查和监测研究。“数字滑坡”技术的实现主要依赖于遥感技术、数字摄影测量及图像处理技术 、GIS技术和计算机技术的支持。该技术大致可分为3大部分： 滑坡基本信息获取、信息存贮和管理及专题服务技术。本文以三峡库 区、四川天台乡滑坡、金龙山滑坡及易贡滑坡遥感调查及监测说明“数字滑坡”技术的专题服务应用。

REMOTE SENSING FOR LANDSLIDES

Remote sensing for landslides in China as a main means for regional landslide investigation has a history of more than 20 years, and has made important contributions to survey, mitigation and prevention of landslide disasters in large-scale engineering construction of mountainous areas. With the adoption of "digital landslide" technique and high resolution remote sensing data since the end of the 20th Century, Remote sensing for landslides has acquired the capacity for more exact qualitative and quantitative landslide survey, even for detailed survey and monitoring of large-size independent landslides. The realization of"digital landslide"technique depends on the support of remote sensing, digital photogrammetry and image-processing, GIS and computer technique. The"digital landslide"technique can be divided into three parts, i.e., acquisition of basic landslide information, information storage and management, and thematic service technique. With Tiantaixiang landslide, Three Gorges area, Jinglong Mountain landslide remote sensing investigation and Yigong landslide remote sensing monitoring as examples, this paper deals with the thematic service technique of "digital landslide".
