Abstract

In order to make a more objective evaluation of the level of coordinated development of the integrated urban disaster prevention complex system, the complex mechanism of coupling and co-evolution is analyzed from five aspects, such as monitoring early warning and prediction, engineering defense, emergency disposal and rescue. By constructing evaluation index system of complex system of urban comprehensive disaster prevention, coupling and coordination degree as input variables, building the coupling coordination degree model, and Jiangxi province as an example for empirical analysis. The results show that the coupling degree of various cities in Jiangxi province is high, which is basically located in (0.8, 1) interval, and there is strong interaction between each subsystem, which belongs to the high level coupling stage. However, the overall coupling of the five subsystems in each city is relatively low, which is basically in the (0.2, 0.4) range, and the benign coupling degree is low, which belongs to the type of mild or moderate disorder. The coordination degree of the subsystem coupling is basically the same as the overall coupling, and the individual cities are slightly different. The results of the coupling coordination in every city show the consistency in spatial distribution and the circular distribution on the radar map.
