摘要

城市内涝是中国城市面临的重大挑战，因此有必要深入了解中国城市抗洪能力的耦合效应，以制定有效的抗洪规划。本研究引入了环境-机构-基础设施-代理（EIFA）四要素框架，并利用最新的关联网络方法，分析了 2012 年至 2022 年中国 639 个城市的城市抗洪能力耦合效应的时间变化。研究结果表明，主要由于机构和基础设施部门内部和之间的竞争加剧、基础设施投资的边际影响以及社会基础设施过剩，协同效应下降，权衡增加。研究还强调了代理部分的强大内部和相互耦合效应，这意味着中国以人为本的抗灾战略是有效的，尽管仍然存在脱钩的风险。此外，研究还注意到社会城市抗洪能力与自然洪水风险之间的良好匹配，而城市扩张导致的自然植被损失值得关注。研究进一步表明，完善以代理人为中心的存款和保险政策可以协调地提高城市抗洪能力，因为这些要素是网络中的枢纽。更新后的基于网络的框架及其发现为中国城市抗洪规划的制定和优化提供了启示。

Coupling dynamics of urban flood resilience in china from 2012 to 2022: A network-based approach

Urban flooding presents a significant challenge in Chinese cities, necessitating a deeper understanding of the coupling effects of China's urban flood resilience for effective resilience planning. This study introduces a four-component Environment-Institution-Infrastructure-Agent (EIFA) framework and utilizes an updated correlation network approach to analyze the temporal variation of coupling effects of urban flood resilience across 639 Chinese cities from 2012 to 2022. The findings indicate a decline in synergy and increased tradeoffs, primarily due to intensified competition within and between institutional and infrastructural sectors, marginal impacts of infrastructure investments, and socially excessive infrastructure. The study also highlights the agent component's strong internal and inter-component coupling effects, implying the effectiveness of China's people-centered resilience strategies, though risks of decoupling remain. Additionally, it notes a good match between societal urban flood resilience and natural flood risks, while natural vegetation loss due to urban expansion is noteworthy. The study further suggests that refining agent-focused deposit and insurance policies could coordinatively enhance urban flood resilience, as these elements are hubs within the network. The updated network-based framework and its findings offer insights for informing and optimizing urban flood resilience planning in China.

期刊介绍： Sustainable Cities and Society (SCS) is an international journal that focuses on fundamental and applied research to promote environmentally sustainable and socially resilient cities. The journal welcomes cross-cutting, multi-disciplinary research in various areas, including: 1. Smart cities and resilient environments; 2. Alternative/clean energy sources, energy distribution, distributed energy generation, and energy demand reduction/management; 3. Monitoring and improving air quality in built environment and cities (e.g., healthy built environment and air quality management); 4. Energy efficient, low/zero carbon, and green buildings/communities; 5. Climate change mitigation and adaptation in urban environments; 6. Green infrastructure and BMPs; 7. Environmental Footprint accounting and management; 8. Urban agriculture and forestry; 9. ICT, smart grid and intelligent infrastructure; 10. Urban design/planning, regulations, legislation, certification, economics, and policy; 11. Social aspects, impacts and resiliency of cities; 12. Behavior monitoring, analysis and change within urban communities; 13. Health monitoring and improvement; 14. Nexus issues related to sustainable cities and societies; 15. Smart city governance; 16. Decision Support Systems for trade-off and uncertainty analysis for improved management of cities and society; 17. Big data, machine learning, and artificial intelligence applications and case studies; 18. Critical infrastructure protection, including security, privacy, forensics, and reliability issues of cyber-physical systems. 19.
