摘要
针对将组合确定赋权法应用于可拓学评价模型中,提出了地质灾害评价的一种新方法.以吉林省地质灾害监测资料为依据,利用物元理论、可拓集合理论及其关联函数,确定了地质灾害的经典域和节域.实验证明,采用模糊层次分析法(FAHP)与熵值法相结合的组合赋权法确定权重,建立了地质灾害可拓学综合评价模型,得出了符合实际的分区等级.
Based on combination weight method in extenics evaluation model, this paper proposed a new geological disaster evaluation method. According to the monitoring data of geological disasters in Jilin Province, and by using matter-element theory, extension set theory and its associated functins, the geological disasters in the field of classical field and the sectin was determined. To determine the weight, we created a geological dis- aster extenics comprehensive evaluation model by the fuzzy analytic hierarchy process（FAHP） and the combination entropy weighting method, and finally go to the realistic district level.
