Abstract

The western Sichuan plateau features a unique natural environment and profound humanistic connotations and boasts its booming tourism. However, Ganzi Prefecture has faced an arduous task in comprehensive prevention and control of geological disasters due to its unique natural environment, development of disaster-inducing factors, weak bearing capacity for disasters and various types of disasters. Due to frequent extreme weather, changeable climate, vulnerable primary environment and frequent natural disasters, e.g. geologic and meteorological disasters, floods, droughts and earthquakes on the Western Sichuan Plateau, the southwestern Sichuan Mountain areas and the mountainous areas around the Sichuan Basin, Sichuan is one of the provinces with the heaviest natural disasters in China. In addition, the extremely heavy rainfall process and earthquake disasters lead to frequent geological disasters such as collapse, hill-creep and debris flow, bringing a severe situation and great losses to Sichuan. Since the hidden dangers of geological hazards are distributed on very high mountains and in a large scale, and covered with vegetation, it is difficult to discover and prevent these hidden dangers. Frequent geological disasters pose a serious threat to the local residents’ life and property safety and seriously hinder the local social and economic development. Risk evaluation of geological disasters in Danba County is of great significance.
