摘要
贡献权重叠加法是对滑坡本底因子和承灾体因子在滑坡发育中的贡献率进行统计后,通过贡献率均值化、规一化处理,利用权重转换模型计算出每一个因子内部的权重——自权重和因子相互之间的权重——互权重。将滑坡因子、承灾体因子和两者的自权重、互权重分别相乘叠加,得到滑坡危险度和易损度区划结果,再将2项结果相乘得出滑坡风险区划结果。
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 （internal weight of each factor） and the mutual-weight （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.
