摘要
基于自然灾害风险形成原理,综合考虑吉林省自然和社会经济现状,从致灾因子的危险性、承灾体的暴露性和脆弱性及防灾减灾能力4个方面选取指标,利用自然灾害风险指数法、加权综合评价法及层次分析法构建生态灾害风险评价模型,评价了各风险因子的贡献率,并运用GIS技术生成吉林省生态灾害风险区划图.评价结果对于正确认识吉林省的生态环境风险水平,有针对性地确定生态恢复与管理决策都有重要意义.
Based on the principles of natural disasters risk formation, and considering the natural and social features of Jilin Province, relevant indices were selected from the aspects of hazard, exposure, vulnerability and emergency responses, and recovery capability, and Natural Disaster Risk Index method, Weighted Comprehensive Analysis, and Analytic Hierarchy Process were used to build the risk assessment model of ecological disasters in this Province. The contribution of each index was assessed, and the regionalization map of the ecological disasters risk in Jilin Province was built based on GIS, which would provide scientific references in accurately understanding the risk level of ecological disasters and in decision-making of eco-environment restoration and management in Jilin Province.
