The Remote Sensing Investigation of the Secondary Geological Hazards Situation in the West Mountain Area of Qingchuan County in Sichuan Province and Suggestions Concerning Prevention and Control

In this paper,the west mountain area of Qingchuan County,one of the most serious earthquake hazards areas in Wenchuan County with representative significance,was chosen as the study area.The relations between the special structural position and the secondary geological hazards were analyzed,the remote sensing interpretation keys to the secondary geological hazards were established,the predominant types of the secondary geological hazards in this area were summarized,and the hazards situation in this area were estimated.On such a basis,some reasonable suggestions concerning the prevention and control of such hazards are put forward.
