China is a mountainous country with complex terrain

active geological structures

and widespread distribution of geological hazards. Due to the frequent occurrence of strong earthquakes and extreme weather events

geological hazards in China have been in a frequent trend in recent years. In order to achieve digital and intelligent management of geological disaster prevention and control

targeted at high-risk prevention areas

a comprehensive and spatiotemporal digital twin model integrating underground 3D geology and above ground 3D reality is constructed

as well as a knowledge graph in the field of geological disasters

accurately reproducing rich information such as mountains

slopes

and disaster bearing bodies in the real world; This paper simulates

analyzes and presents the characteristics and trends of geological hazard changes

create a full lifecycle management business chain for normal monitoring

risk prediction

accurate warning

and scientific disposal of geological hazards

and achieve collaborative and intelligent management decisions for geological hazard prevention and control that are traceable in history

perceptible in current situation

and predictable in the future.
