Landslide risk zoning based on the contributing weight stack method

The contributing weight stack method can be used for zoning of landslide risk. After the statistics of the contribution rates of the background factor of the landslide and the factor of the bearer in the landslide development, the authors calculate the self-weight W (internal weight of each factor) and the mutual–weight W＇ (weight between different factors) through equalization, normalization and weight conversion. Then the landslide factor and bearer factor multiply their self-weigh and mutual–weigh respectively to get the results of the landslide danger zoning and vulnerability zoning. Finally, the results of the two items are multiplied and the landslide risk zoning is got.
