摘要
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.
