摘要:

Integrated defense against earthquake disaster is an urgent problem. In this paper, the basic principle of urban multi-lines for seismic defense was proposed. The basic theory of defense periphery for urban earthquake disaster was established. The exchange rate between periphery groups was regard as control variable, and the Lotka-Volterra model was introduced into defense periphery system. The evolution model of urban multi-lines for earthquake disaster defense was set up, which explained the competition and collaboration dynamic mechanism of urban multi-lines for seismic defense. The order parameters of multi-lines defense system were selected according to synergy principle. The co-evolution measurement model of urban multi-lines for defensing earthquake was established, and it was applied to Nantong city earthquake disaster integrated defense system. The result shows that competition alienation characteristics of defense system arise, and system coordination degree is reduced to 0.62. The system is restored to the previous level of coordination degree, and it is developing towards coordinated direction by adjusting the input proportion of multi-lines for seismic defense.
