    A survey and study of the Xiaobao rock avalanches based on Quickbird satellite images

    • 摘要: 提要:遥感技术为地质灾害调查研究提供了新的途径和手段,已成为地质灾害调查研究的一种重要技术手段,特别是高分辨率的Quickbird卫星影像在地质灾害的调查研究中有着广泛的应用。笔者在研究汉源县小堡崩塌群时,采用Quickbird卫星影像,通过遥感数字图像处理,获得高精度的遥感影像图作为地质灾害遥感研究的数据源,并进行遥感解译,总结小堡崩塌群的遥感影像特征。根据遥感影像特征来判定其规模、稳定性、危害程度和发展趋势,并分析其形成条件和影响因素。

       

      Abstract: Abstract:Remote sensing technology for geological hazards survey and research providing new ways and means of investigation and study of geological hazards has become an important technical means, and high-resolution Quickbird satellite images in geological hazards research have an especially wide application. In this paper, the authors studied the Xiaobao rock avalanches in Hanyuan County and used Quickbird satellite images and remote sensing digital image processing to obtain high-precision remote sensing image as the data source for the study of geological hazards and remote sensing interpretation. Image features of the Xiaobao rock avalanches were summed up. According to remote sensing image features, the size, stability, harmful extent and development trend of the Xiaobao rock avalanches were judged, and its formation conditions and affecting factors were analyzed.
