- Abstract:
-
From seven aspects:topography,geology,climate,hydrology,vegetation,disaster situation,and human activities,11 factors are selected to evaluate the Wenchuan Earthquake-induced disasters by using a combination of qualitative and quantitative methods,with the help of risk index.According to regional factors,and “the same or similar classification,the different classification” principle,together with the use of GIS technology,the study area is divided into 4 grades:high risk areas,medium-risk areas,low-risk areas and safety areas.By conducting secondary mountain hazard assessment and zoning as well as the use of optimal cost model of disaster risk reduction into the economic evaluation,reasonable disaster prevention and mitigation measures and suggestions are raised.
