Evaluation of the geological disaster susceptibility in Chifeng city based on the hierarchi-cal analysis method
In this paper,the geological hazard susceptibility of Chifeng city in Inner Mongolia Autonomous Re-gion is evaluated by AHP.The main conclusions are as follows:Based on the comparison between the disaster sites and the geological disaster susceptibility zoning results in this paper,analytic hierarchy process is suitable for geologi-cal disaster susceptibility assessment in Chifeng city;In Chifeng city,the regional area of non-prone,low-prone,medi-um-prone and high-prone areas of geological disasters accounted for 37%,19.2%,30.6%and 13.2%,respectively;Most of the whole area of Chifeng city is in the middle and high prone area of geological disasters,which are mainly distributed in the hilly and mountainous areas of north-south trend;The low-prone and non-prone areas are mainly distributed in the eastern plain and the western high plain.
