摘要：Rapid urbanization has exacerbated the urban heat island (UHI) effect, while limited urban space restricts the implementation of blue-green space-based infrastructure for climate adaptation and urban cooling. To address this, the Cold Island Network (CIN) approach integrates cold island resources to enhance synergistic cooling effects within a holistic network. This study focuses on Fuzhou City, one of China's "top ten furnace cities." Using land surface temperature inversion, we analyzed the spatial characteristics of UHI. Based on Circuit Theory (CT), the CIN was constructed by integrating 2D and 3D urban indicators and anthropogenic heat data. The results showed that 217 Cold Island Core Sources, 324 cooling corridors, 76 cooling nodes along with 90 heating nodes were identified. The structural stability of the CIN under different scenarios were derived through complex network simulation and evaluation. Results show that the constructed CIN is resilient to interference, prioritizing high-centrality patches is a cost-effective way to enhance its robustness. Corridors and nodes were verified through satellite imagery and field surveys to ensure accuracy, based on which corridors were categorized to guide targeted planning strategies. Our results offer valuable insights into climate-resilient urban planning and UHI mitigation, contributing to urban sustainable development. ? 2025 Elsevier Ltd
