Landslide Risk Zoning Based on Contribution Rate Weight Stack Method

The contributing weight stack method can be used for zoning of landslide risk. After statistics of the contribution rates of the background factor of the landslide in the landslide development, the authors calculate the self-weight (internal weight of each factor) and the mutual-weight (weight between different factors) through equalization, normalization and weight conversion. Then the landslide factor multiply their self-weight and mutual-weight respectively to get the results of the landslide danger zoning. Application of this method in conjunction with GIS technology in the southeast coastal areas, by carrying out research on landslide danger zoning, the authors can be draw conclusions that the results matched with the actual situation by statistic treatment.
