摘要:
从地形地貌、地质、气候、水文、植被、灾害状况、人类活动等7个方面选取11个因子,采用定性与定量相结合的方法,引入危险性指数来评价汶川地震次生山地灾害的危险性大小,并利用GIS技术,按区域因素“相同或相似归类、相异分级”的原则,将研究区分为高度危险区、中度危险区、低度危险区和无危险区等四个等级,进行次生山地灾害危险性评价与区划,并运用最优灾害成本模型对减灾投入进行经济性评价,从而提出合理的防灾减灾对策与建议.
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.
