[Risk assessment of ecological disasters in Jilin Province based on GIS].
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.
