<正>0 INTRODUCTION Landslide is one of the most common and serious natural disasters in the world, which causes great damage to social development and people ' s life and property safety(Wei et al., 2024; Froude and Petley, 2018). Landslides are responsible for an average of thousands of deaths and billions of economic losses annually(Dai et al., 2023). The study of landslide geomorphology plays a crucial role in many aspects such as landslide formation mechanisms, dynamic process, and prevention and control(Hou et al., 2024; Wang et al., 2024), and provides scientific support for infrastructure construction, road route selection, and urban land planning(Vargas-Cuervo et al., 2024; Laimer, 2017). Therefore, it is essential to gain a better understanding of those roles and to further contribute to disaster prevention and reduction.
