基于模糊综合评判法的苏宝河流域地震滑坡潜在危险性评判

Assessment on Potential Hazards of Seismic Landslide in Subao River Basin Based on Fuzzy Comprehensive Evaluation Method

对地震滑坡区域危险性进行评判时,因其影响因子较多,具有模糊性,目前还没有建立统一的评判方法。利用模糊综合判别法对滑坡区域危险度进行评判,能够充分地考虑各种影响因子的作用,相对于其它评判方法更具有优势。以苏宝河流域为研究对象,基于模糊综合评判法,选取影响地震滑坡发育的本底因子,建立了该区域地震滑坡潜在危险性评判模型,对该区域地震滑坡潜在危险性进行评判,并取得了较好的效果。

Currently, there has not an unified method to evaluate the hazards in seismic landslide area,because the influencing factors are different and fuzzy. The evaluation of risks in landslide area by luzzy comprehensive evaluation method may take various factors into consideration and, compared to other evaluation methods, has more advantages. Taking Subao River Basin as the study object, and selecting the background factors influencing seismic landslide development, the evaluation model for potential hazard of seismic landslide in this ares was established on the basis of fuzzy comprehensive evaluation method to evaluate these risks, and got good result.
