Abstract

Fire emergency service is an important part of urban public health and safety system,and the rationality of its layout directly affects the efficiency of disaster relief response. In this paper, the central urban area of Kunming City is selected as the study area, based on POI, road network and other geospatial data, through AHP hierarchical analysis method and SAVEE model, to realize the identification of potential fire risk area and suitable area for fire stations siting in the study area, and to use the model for minimizing the Number of facilities for spatial optimization of fire station siting. The results show that: 1) the fire risk assessment system is applicable to the study area, and the fire risk is mainly distributed in the northwestern part of the study area; 2) the layout of the existing fire stations is limited, and the existing coverage rate reaches only 71.47%; 3) 6 new fire station sites are added, and the coverage rate increases by 19.75%, and the total coverage rate reaches 91.22%, and the optimized indexes have been greatly improved.
