The effect of hazard was determined by the dangerous degree of hazard factor—environment and the vulnerable degree of sustaining body. The research into the latter is of importance for the hazard theory and the formation of laws on the mitigation of natural hazards. The way to evaluate the vulnerable degree is the foundation of and the key to the research. In this paper, the extenics model is established to do this job.
