With the development of tourism and the acceleration of urbanization, tourist cities have sprung up like bamboo shoots. Large population flow and more cultural relics are the characteristics of the current tourist city, which brings greater fire risk. The current research pays little attention to fire safety problems in tourist cities. This article takes the urban area of Dujiangyan, a tourist city, as the research object, and uses the superposition tool of GIS to make a fire risk grade map with a total of 9 factors of regional characteristics and architectural characteristics superimposed by weight. The result shows that there are still many areas with high fire risk in Dujiangyan, such as the ancient urban area where tourists gather and the southwest sub-area of Dujiangyan urban area. Based on the positioning and distribution model, 6 new fire station layout points are selected, and the responsibility division map of 9 fire stations in Dujiangyan City is finally obtained, which provides a reference for the layout of fire stations in Dujiangyan City.

Strip packing problems is one important sub-problem of the Cutting stock problems. Its application domains include sheet metal, ship making, wood, furniture, garment, shoes and glass. In this paper, a hierarchical layout design method based on rubber band potential-energy descending was proposed. The basic concept of the rubber band enclosing model was described in detail. We divided the layout process into three different stages: initial layout stage, rubber band enclosing stage and local adjustment stage. In different stages, the most efficient strategies were employed for further improving the layout solution. Computational results show that the proposed method performed better than the GLSHA algorithm for three out of nine instances in utilization.
