摘要

针对地质灾害易发程度分区评价遇到的实际问题，采用构建三标度（-1，0，1）矩阵的方法，引入最优传递矩阵，对传统层次分析法构建判断矩阵时权重选择的模糊性和判断矩阵的一致性检验进行了改进;解决了层次结构模型中各个评价因素权重量化的难题，从而得到改进的AHP模型。并以具体地质灾害易发程度分区评价为例，详细地分析了该方法的实践。基于该方法的永川区地质灾害易发程度分区评价实践表明评价结果与实际情况吻合很好。

Abstract

Based on the problem during the practice in geological hazard susceptibility zoning

by constructing the threemark (-1，0，1) matrix and introducing optimum transfer matrix

the faintness about weight choice and the consistency check method of judgment matrix for traditional AHP were improved，and the difficult weight quantization problem for each appraise factor of the hiberarchy model had been solved; accordingly

the Improved AHP model had been built. At the last

this method was applied to a concrete zoning practice about geological hazard susceptibility.The application result shows that the zoning practice in Yongchuan region about geological hazard susceptibility is practical and effective.
