This paper presents a model of risk assessment of geological disasters by using natural disaster risk index method, weighted comprehensive analysis and analytic hierarchy process. The risk of the geological disasters in Xingwen County´s towns is assessed on basis of the risk assessment model.

The results of the assessment were verified using the geological disasters location data, and strongly help the local authorities in their decision making for the disasters´ prevention and reduction of Xingwen county.
