英文摘要	With the development and expansion of landslide research, quantitatively conducting typical landslide hazard assessment is demonstrated to be an effective method in assessing landslide hazard. This study sets up an index system for landslide hazard assessment by means of intensity factors and probability factors of landslide occurrence. Based on the information entropy method, subjective weight was calculated for 21 typical landslides in Wushan County, located in the Three Gorges Reservoir area, and a qualitative typical landslide hazard degree assessment model was established. This model was then used in evaluating the hazard degree of the landslides in Wushan County, and the results were contrasted and confirmed through field investigation. The accuracy rate of the investigation is as high as 90.4%. As a result, this model demonstrates a useful application of a new methodology and provides a basis for future warning and hazard evaluations of a typical landslide.
