Abstract
This study intends to discuss the urban space planning’s function position of urban disaster prevention and its implementation. According to the literature concerning urban disaster prevention and urban planning as well as the actual implementation of urban disaster prevention in Taiwan, US and Japan, 17 categories and 137 items of urban disaster prevention planning manners were classified and an operating system to understand the pattern of the urban disaster prevention was developed in the study. Based on the operating system and understanding of the pattern of the urban disaster prevention, 7 categories and 31 measures of spatial mitigation for disaster prevention were generalized by combining knowledges from literature relative to land use planning and the strategies of urban disaster prevention. After that, a questionnaire survey concerning spatial mitigation of urban disaster prevention was carried out with relating specialists in Taiwan. The fuzzy Delphi method was then applied to analyze the data from the survey to prioritize the 7 categories and 31 measures of spatial mitigation for disaster prevention and to find appropriate ways to implement these measures in urban planning. The specialist survey results showed that the first 15 measures of importance of spatial mitigation were listed from the most important to the least as follows; Evaluation of the possible influence of disasters in local areas, Restriction on the land use in the high hazard prone areas, Reconstruction of public infrastructures (including traffic facilities and life-line systems), Constitution of disaster prevention rules within the zoning regulations, Assessment of vulnerability of the areas in critical development projects, Analysis of the hazards potential, current and historical condition , Layouts of high hazard prone areas and its measures of prohibiting and limiting of development, Plan for crucial/basic public infrastructures to prevent urban development vulnerable to natural disasters, Seismic evaluation, disaster prevention planning and strengthening of the public infrastructures and life-line systems, Reconstruction of residental areas and communities, Drawing the disaster prevention spatial systems, Scheming the Regional Disaster Prevention and Response Plan, Drawing and releasing maps of the natural hazards potential map, Scheming reconstruction plans for the damaged urban areas (including urban renewal plans), Carrying out planning permission system in high hazard prone areas. In-depth interviews and discussions concerning the above mentioned fifteen spatial mitigation measures were also carried out with relating specialists in Taiwan for information of how those measures are operated currently and opinions on how to implement them into urban planning. In the end, the study tried to provide suggestions on implementation of spatial mitigation measures and how to apply them into urban planning.
