| 英文摘要 | Spatial networks of urban heat islands (UHIs) within urban agglomerations are characterized by a non-trivial topology. They critically influence regional climate dynamics and promote coordinated development. For the first time at the national scale, this study constructs a 15-year comparative framework for 19 major Chinese urban agglomerations by systematically integrating multi-source thermal remote sensing data, morphological spatial pattern analysis (MPSA), resistance-based circuit modeling, and complex network robustness theory. A combination of the Simplified Urban Extent algorithm, MSPA, circuit theory, and simulation of network robustness not only identified and quantified UHI connectivity patterns but also evaluated their systemic vulnerabilities under both random and targeted node-removal scenarios. This enabled resilience-oriented optimization. The results show that the area of summer UHI patches in the 19 agglomerations expanded significantly from 6.79 x 104 km2 in 2005 to 1.52 x 105 km2 in 2020. Correspondingly, the total length of the spatial networks increased from 5.79 x 104 to 9.98 x 104 km, with the density rising by 0.01 km.km-2, reflecting both large-scale spatial expansion and enhanced inter-patch connectivity. Targeted attack simulations further revealed that removal of structurally critical nodes-identified via multi-metric network centrality assessment-reduced network resilience by 35-60 % more than did random disruptions, highlighting the roles played by key spatial hubs in terms of maintaining UHI network stability. These findings bridge landscape ecology and complex network science, offering a transferable resilience-oriented framework for optimization of urban climate networks and heat risk mitigation in rapidly urbanizing regions. |
