- Abstract:
- This article discussed the hazard assessment of geohazards triggered method using the model of fuzzy comprehensive evaluation and GIS system. Selecting the Geohazards frequency of the terrain gradient, altitude, stratigraphic lithology, rivers buffer, fault buffer in the study area as evaluation index, fuzzy comprehensive evaluation method is used for geological hazard assessment, based on the powerful spatial analysis functions system of GIS, to achieve geographical data processing operations. Finally, A case study in Maoxian County of Sichuan Province after the 5·12 Wenchuan earthquake, complete the hazard assessment of geohazards of stuty area. The results show that high-hazard area accounts for 25.0 percent and the nambers of geohazards in the study area accounts for 60.7 percent; moderate-hazard area accounts for 33.1 percent and the numbers of geohazards in this area accounts for 24.4 percent; low-hazard area accounts for 41.9 percent and the numbers of geohazards in this area accounts for 14.9 percent,Geohazards hazard assessment in earthquake areas can provide scientific suggestions for reconstruction and government decisions making.
