Geomorphological features are commonly used to identify potential landslides. Nevertheless, overemphasis on these could lead misjudgment. This research proposes a process-oriented approach for landslide identification that considers time-dependent behaviors. The method integrates comprehensive remote sensing and geological analysis qualitatively assess slope stability, employs numerical quantitatively calculate aging stability. Specifically, stability calculation anticlinal slopes is developed implemented in discrete element software, incorporating mechanical strength reduction calculations. By considering the evolution of slopes, this highlights importance both geomorphological behaviors identification. has been applied Jiarishan (JRS) Qinghai-Tibet Plateau as case study. results show JRS, despite having geomorphology, stable slope, highlighting risk misjudgment when relying solely features. work provides insights into characterization history JRS offers valuable guidance studying with similar geomorphology. Furthermore, means evaluate landslides, reducing due excessive reliance
