摘要

To mitigate the intensifying urban heat island (UHI) effect, this study establishes a framework for identifying urban ventilation corridors in Nanchang city of China. We constructed a Comprehensive Ventilation Resistance Coefficient (CVRC) model based on building morphology, NDVI, and M-NDWI, and applied circuit theory to identify corridors. Analysis of land surface temperature (LST) and meteorological data confirmed severe summer UHI, with over 48% of the area as medium/high-temperature zones in Nanchang. The results demonstrate the corridors’ effectiveness, showing significantly lower temperatures and higher ventilation efficiency than non-ventilated areas. Meanwhile, this study proposed a viable ventilation network of 5 primary, 7 secondary, and 9 tertiary pathways. This work provides a scientifically-grounded framework for urban ventilation planning, offering both theoretical innovation in corridor identification and practical value for mitigating thermal stress in Nanchang and similar cities.
