Since Taiwan is located in a disaster prone area, how to reduce vulnerabilities and enhance resilience of environment have become very important issues for spatial planning and management for different levels of government. This study tries to apply concepts to urban level spatial planning and management and establishes assessment indictors and a model. The purpose of this research is to apply fuzzy Delphi and analytical network processes to flood adaptation strategic planning. This study establishes a proper adaptation strategy assessment model which is suitable at the urban level. Through this kind of research we provide some principles and strategies for future spatial planning and disaster management policies, including strengthening ecological land-use planning, prohibiting overload exploitation, strengthening the conservation of catchment areas, establishing growth control quotas, delineating the counties of the national conservation area, and making overall inspections to the urban planning.
