Abstract: Duwen highway in Sichuan province is located in the strong earthquake zone of the 2008 Wenchuan earthquake， where post-earthquake debris flow disasters are exceptionally active. In this study， pre-earthquake DEM， post-earthquake Landsat TM multi-band fusion data， and two-phase full-color band remote sensing data of typical debris flow gullies in the area were selected to analyze the characteristics and evolution of debris flow source development. The results show that the development of debris f... More
