The projection model is obtained by combining the post-disaster city information and the city resilience index, and the projection model is transmitted to the information visualization subsystem and the city planning subsystem.

[0035] The information visualization subsystem is used to visualize the city information, visualize the simulation results output by the simulation engine subsystem and the city resilience index. The city basic information is displayed by the layering idea, the city supplementary information is displayed on the page, the resilience function simulation result is displayed in the corresponding layer, and the corresponding interactive interface is provided for the user to interact with each subsystem.

[0036] The city planning subsystem includes a planning model, which automatically generates the city planning for the city basic information according to the projection model of the simulation engine subsystem. At the same time, the subsystem also provides a visual interface to modify specific city information and modify the planning model to achieve manual planning. Finally, the city planning result is stored in the city information subsystem.

[0037] In this embodiment, the city resilience is not measured by specific indicators, but by the service ability of the city to provide services for residents to measure the relative resilience of the city.

And the projection model is obtained by combining the post-disaster city information and the city resilience index.

[0045] Then, the simulation engine subsystem is used, as shown in Figure 5 For the flood disaster scenario, a one-dimensional sewer-two-dimensional surface coupling model is selected to simulate the disaster, and the post-disaster city information is output, including overflow information, range, depth and speed, thereby affecting the city road network and changing the city road network as the basic information.

[0046] In terms of the resilience index, in view of the fact that the road network information changes, the city connectivity subgraph is selected as the resilience measure to measure the commuting service ability provided by the city road network and to measure the performance of the city road network.
