  • This article makes use of detailed geo-hazard investigation data in 12 districts and counties of Baoji City in recent 7 years, based on collecting and sorting out main types and spatial distribution characteristics of geologic disasters in Baoji area, and analyses the general development characteristics, different development characteristics of various geologic disasters types in Baoji area and their impacts. It is preliminarily revealed that development types of geologic disasters in Baoji city mainly include:landslide, collapse, debris flow and unstable slope. These geo-hazards generally indicate clustering, unexpected, periodic and in chainlike. Development characteristics among all types of disasters, landslides and collapses happen most frequently and cause serious damage. Debris flows account for relatively rare part. Unstable slopes often occur together with collapses and mainly prone to collapse disaster. In each year, the heavy rainfall during rainy season will induce small scale landslides and collapses, especially the loess landslide and collapse in front of and behind of houses in urban residential area. Eluvia layer landslides and collapses due to slop cutting of mountain roads which occur frequently need to be paid special attention to monitoring, prevention and reduction of geologic disasters in Baoji city.
