Study on the Relationship Between Ecological Transformation of Urban Infrastructure and Urban Resilience-Based on Complex System Perspective
At present,there is still a lack of mature linkage mechanism between urban ecological transformation and urban resilience improvement in China,which makes it difficult for urban construction to find the focus point of resilience development on the original ecological base.Based on the theory of complex adaptive system,this paper constructs the research framework of urban resilience system.Using the sample data of China from 2010 to 2022,the system dynamics and coupling coordination degree model are used to simulate the change process of urban resilience under different urban infrastructure transformation strategies,and the resilience simulation results are obtained under two disturbance erturbation scenarios and six development strategies respectively.The results show that:①Among the ecological transformation strategies,the enclave new construction strategy has the most obvious effect on the ecological,economic and social resilience of the city,followed by"ecology＞industry＞community".②The single continuation of development has the worst effect on all aspects of urban resilience,while the effects of the transformation strategy and the synergistic development strategy depend on the specific perturbation scenarios.③For urban resilience as a whole,synergistic development strategies are most effective under short-term and chronic disturbance perspectives,while transformational development strategies have greater potential for development under long-term or acute disaster shocks.④ China's overall urban resilience subsystems have only reached a barely coordinated state,and enhancing the coupling correlation among the three subsystems is an effective strategy to enhance the capacity and resilience of urban ecological transformation in the future.
