Abstract

The marine cooling effect (MCE) plays a crucial role in mitigating urban heat island (UHI) in coastal cities. However, limited research has explored how urban spatial forms (USF) influence MCE, particularly between mainland and island regions, which may exhibit distinct cooling dynamics. This study proposes a marine cooling spatial impact value (SIV) index to quantify the impacts of USF on MCE. Utilizing interpretable machine learning models, we explore the nonlinear impacts of key USF on MCE. The research shows that MCE extends further on Xiamen Island than on the mainland. Specially, water bodies enhance MCE, while both impervious surfaces (Im_p) and building density (BD) weaken it. Moreover, elevation - waters interaction enhances their MCE contribution on the mainland, while waters - canopy height (CHM) interaction boosts CHM's contribution on island. This study emphasizes the significant role of the 3D structure of urban forms in shaping MCE, highlighting notable differences between island and mainland regions. Our findings offer a new framework for quantifying the USF-MCE relationship and provide valuable guidance for coastal urban planners to optimize spatial layouts and effectively mitigate UHI effects by considering regional differences in MCE.

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. Water footprint reduction and urban water distribution, harvesting, treatment, reuse and management; 20. Waste reduction and recycling; 21. Wastewater collection, treatment and recycling; 22. Smart, clean and healthy transportation systems and infrastructure;
