基于高空间分辨率卫星影像的黄土滑坡灾害解译

On Landslide Interpretation Based on the High Spatial Resolution Satelite Images

黄土高原地域广袤，地形破砗，暴雨集中，地质灾害频发，为地质灾害防治工作带来了诸多困难。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、准确地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。

China is one of the countries that are frequently and seriously affected by geological disasters. Therefore it is of great significance to know swiftly and precisely the distribution and characteristics of the geological disasters via the high - resolutioned satellite video fusion technology. With the development of the remote sensing technology, spatial resolution of the remote sensing data could make the extraction and interpretion of the landslides geological disaster information come true. This paper takes the high - resolutioned Spot 5 data for example, analy- ses geological disasters of landslides and geological environment conditions and geological disaster information obtained, which gives typical samples for landslide interpretation of geological disasters by the remote sensing technology.
