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 disaster 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.
