The purpose of this research is to construct a spatial analysis model for disaster potential index of urban land uses. The relationship between land uses and environmental hazards were studied and intergraded into the model. The hazards were categorized into two types, continuous and discrete. The potential impact for each type was calculated separately and then combined into a single hazard index. The IDW (Inversed Distance Weighted) was used to calculate the distribution of hazard potential from land use. The hazardous land uses used in constructing the model include fire, air pollution, and magnetic field.
Urban land use data of Taichung City was collected through field survey and converted into an ArcView GIS database. By using Spatial Analysis Module from Arc View GIS 3.1, the results from analysis show the high relationship between potential hazard and the types of land uses. The locations of daycare centers and distribution of population were overlaid with the distribution of hazard potential to demonstrate the impact from these hazardous land uses in Taichung City.
The resulting distribution map will provide government vital information in decision-making on urban development and planning.
