Natural disasters cause serious damage to buildings and infrastructure, and victims lose a comfortable living environment. A large number of people are left homeless. Emergency shelter is an important component that cannot be ignored in the comprehensive disaster prevention and mitigation plan. However, to the best of our knowledge, no study has collectively taken into account the rapid and accurate resettlement of evacuees by taking stratification of demand, distribution of supplies, and diversion evacuation as an organic model. Given the bottleneck of rapid and accurate resettlement in the complex sheltered environment, we combine field research, literature analysis, and previous case study. This paper explains that the three main factors that affect the resettlement of evacuees are the complexity of demand, the shortage of materials, and the blindness of refuge. Additionally, then an effective analysis framework of the hierarchy of demand, distribution rapidity and refuge accuracy are constructed. Finally, this paper puts forward the structural framework of demand for layered, comprehensive distribution and diversion of evacuees and further explains the structure relationship, mode of rescue and operation strategy of effective resettlement of evacuees.
