Research on fine Spatial Quantitative Model about vulnerability of hazard-affected bodies

Abstract

The seriousness of losses caused by disaster dependent on the hazard degree of environment, vulnerability of hazard-affected bodies, and emergency response capacity of the region is studied in this article. The study on hazard-affected bodies is of importance to disaster risk management, regional hazard prevention, reduction, and investment in disaster insurance. With summarizing of various assessment methods of vulnerability of hazard-affected bodies, this paper presents a refined Spatial Quantification Model of regional vulnerability which combines refined spatial geographic data and land-use type data. A quantitative study on regional vulnerability was carried out by defining fine spatial grid as the basic evaluation unit based on GIS. © 2010 Taylor & Francis.
