基于高空间分辨率卫星影像的黄土滑坡灾害解译

摘要

The Loess Plateau is vast and vulnerable to serious and frequent geological disasters such as storms. As an advanced technology, remote sensing is playing an important role in de-tecting geological disasters. The satellite images of high spatial resolution can quickly determine the distribution, scale and affected objects and therefore is of great significance for the preven-ting and controlling of natural disasters. Based on data SPOT-5 of high spatial resolution, an analysis is made of the remote sensing and the information extraction of landslides. The outcome is supposed to serve as an example of remote sensing interpretation of geological disaster.%黄土高原地域广袤，地形破碎，暴雨集中，地质灾害频发，为地质灾害防治工作带来了诸多的困难。遥感作为一个先进技术已在区域地质灾害宏观调查中发挥了重要作用，特别是通过高分辨率卫星影像能快速、准确的分辨和了解地质灾害的分布、规模及危害对象，对黄土高原区地质灾害的防治工作具有重要的指导作用和意义。以高空间分辨率的SPOT-5数据为例，分析了对黄土滑坡灾害遥感解译标志与信息提取，为黄土高原地区的遥感解译地质灾害提供示例。
