Comprehensive Risk Assessment of Urban Waterlogging Disaster Based on MCDA-GIS Integration: The Case Study of Changchun, China

Urban waterlogging will harm economic development and people’s life safety; however, the risk zoning map provides necessary decision support for management of urban waterlogging, planning. This paper proposes an assessment method that combines multi-criteria analysis (MCDA) with a geographic information system (GIS). The framework includes four main elements: hazard, exposure, vulnerability, emergency response recovery capability. Therefore, we selected area Changchun City, Jilin Province as study area. Analytic Hierarchy Process (AHP) is generally accepted MCDA method, it used to calculate weight generate result hazards, responses Based principle natural disaster formation, total 18 parameters, including spatial data attribute data, were collected in this study. model results are compared recorded points, show more reliable.
