Abstract: The recovery of a region which suffers from a disaster or an incident is very important for the victims and the emergency management. The recoverability includes two aspects, the recoverability of the region and the recoverability of some necessary functions which can help support the operation of people’s safety guard or daily life. From the view of time cycle, recoverability can be divided into two stages, emergency response and post-disaster reconstruction stage. The two stages have different characters in damaged things, time, cost and levels. The recoverability assessment requires two types of assessment: the assessment of the priority to different types of damaged things and the assessment of how to recover a certain type of damaged things. The former assessment model is given based on the needs of people, the significance of things and the damage of things, while the latter assessment model is given based on the needs of people, the damage of things, time, cost and indirect loss. Some typically cases are studied to verify the reliability and applicability of the assessment model
