Abstract: The danger level of geological hazards is a comprehensive reflection of the density of occurrence, extent of activity and frequency of occurrence of geological hazards.From this view, this paper discusses the structure of danger of geological hazards and method of its assessment. On that basis, the dangerous assessment and divisions of collapses, landslide and debris flows of geological hazards are made with counties (cities, districts and banners) and provinces (municipalities directly under the Central Government and autonomous regions) as the units, and the dangerous distribution and the law of regional changes of geological hazards are analyzed.
