摘要
In the classification model of geological hazard, the factors of the geological disaster in different parts have different weights. The accuracy of the weight will directly relate to the reliability of zoning. According to the frequency distribution of the geological hazard in different regions, the relative size of the contribution of the different factors is derived. The contributions of the factors are in fact the weight of them in the model of geological disaster-prone. Based on the above analysis, the relative weights of the factors are obtained. Then the weight factors are calculated by AHP method. The method reduces the arbitrariness of human and improves the accuracy of division. oft-com:office:office" />
