Contributing weight overlay model can be used as a kind of landslide hazard zonation methods. It is a GIS-based pixel-by-pixel analysis. Firstly, the method determines the event-controlling parameters and divides them into subtypes, then, calculates statistical correlations between the subtypes and landslide inventory, compares the number, area, and volume of landslides occupied by the factors subtypes with the number, area and volume of landslides in the factors. Contribution ratios of subtypes of different factors will be got. By using equalization and normalizing processes to the contribution ratio,it is possible to calculate every factor' s self-weight and mutualweight. Finally, through making an overlay by multiplying contribution ratios, self-weights and mutual-weights, the level of regional-scale landslide hazard can be determined. This method is simple and easy to use. Event-controlling factors can be obtained from digital maps or field survey directly. Quantitative effect is satisfied
