| 摘 要： | 鉴于地质灾害危险性评价中现有确定指标权重的方法存在的诸多不足,根据多目标决策理论和层次分析法基本原理,提出改进模糊层次分析法确定地质灾害危险性评价指标权重的应用模型,使之求得的评价指标权重更为合理。并在此基础上,以浙江省青田县地质灾害危险性评价为例,验证了该方法的可行性和优越性。

| Abstract: | Considering lots of deficiencies of the present method for confirming the weight of indexes in ecological disaster risk evaluation,according to multi-objective decision-making theory and the basic principle of analytic hierarchy process(AHP),the applied model of improved fuzzy AHP was put forward for confirming the weight of risk evaluation indexes in ecological disaster, which made the calculated weights of evaluation indexes more reasonable.Based on this,taking the ecological disaster risk evaluation in Qingtian County of Zhejiang province as an example,the feasibility and superiority of this method were validated. |
