Because the improper exploitation of natural resources under global climate change that aggravates disasters to human society. Therefore, in order to reduce losses caused by disasters there are more attention to international issues related to vulnerability. To assess the natural and social environment confronts by natural disasters against the impact of vulnerability. Vulnerability, broadly defined as the potential for loss, is an essential concept in hazards research and is a central to the developments of hazard mitigation strategies. The place vulnerability is an extension of vulnerability. In the spatial aspects, the areas for development within the elements by differences in the subject to external stress, such as typhoons, floods, government policies, and so on, how an area can bear under the existing conditions. This research uses the hazards-of-place model of vulnerability is proposed by Cutter (1996) from the literature review to identify the meaning of vulnerability. This paper presents a method for assessing the place vulnerability using both biophysical and social indicators. Two dimensions, six sub-dimensions and fourteen criteria are chosen. Definition of each indicator how to measure and the vulnerability of the negative and the positive association must be defined clearly. We utilize the way of normalization in order to unite the aspect of the indicators. The evaluation of the indicators should be able to explain the relationship of the vulnerability between the areas. Next the weights of the indicators are integrated by ANP. Through measuring the relative importance between the various indicators conducts the effective and accurate assessment. Then we use the simple weighted method to integrate indicators for calculating the place vulnerability of overall regions. The results indicate that the “spatial area ratio of disaster prevention” and the “density ratio of main road extension” are the most significant indicators in the assessment for affect the place vulnerability. Although the “proportion of people with disability” is also a key factor, the social environment conditions are improved only through long-term way to reduce them exposure to risk. Besides, the find that Fusing Township is the most vulnerable area in Taoyuan County. If when the disaster occurs, the more prone to the large-scale losses. Finally, we group the individuals that have the same critical influencing factors by cluster analysis and can be divided into four groups. The townships have similar features to be joint development as a spatial development zone through the regional strategy. Afterward we formulate strategies to reduce an unbalanced distribution of resources of disaster prevention between urban and rural areas.
