Abstract

The balanced layout of emergency shelters, which can be measured by spatial accessibility, is an important component of the urban disaster prevention and mitigation system. Among the various research methods, the two-step floating catchment area method (2SFCA) is a more comprehensive and convenient way. To address the problems in the 2SFCA method applied in the emergency shelter accessibility, we propose a 2SFCA method coupled with the network analysis method to evaluate the shelter accessibility in Changchun and find the problems of the emergency shelter layout and finally put forward the corresponding planning advice. The results indicate that the equity of the emergency shelter layout is poor in some area of Changchun, and the shelter distribution needs to be adjusted according to the trend of the population and road distribution.
