Abstract: Landslide is a typical and frequent geological disaster, which causes great loss to human beings. Major landslide hazards, such as landslides in high mountains and ice avalanches,have become important constraints to the development of urbanization and major infrastructure projects such as the Sichuan-Tibet railway. This paper systematically analyzes the characteristics and limitations of existing monitoring technology and analysis methods of potential landslide hazards, introduces a reliable method for potential landslide hazards analysis by coupling monitoring data with mechanism models, to establish the knowledge graph for potential landslide hazards analysis, to extract the high-level semantic features and to identify the potential landslide hazards precisely guided by knowledge.This method systematically considers the mechanism of landslide disaster caused by the coupling of deep and surface, and provides a new way for the reliable analysis of potential landslide hazards with small sample and high complexity.

Key words: potential landslide hazards, geographical environment, monitoring technology, analytical method, knowledge graph
