Abstract: Many cities have substantially expanded urban tree cover yet continue to experience intensifying heat stress that threatens public health, infrastructure and climate resilience. By contrast, traditional Chinese villages have demonstrated lasting thermal resilience through a synergistic mountain–water–forest framework that functions as a holistic climatic regulator. Building on this principle, we adapt and validate this cooling framework for modern megacities across diverse climatic zones and morphological contexts. Leveraging cold-air advection driven by terrainguided wind patterns and upwind greening, the mountain–water–forest framework yields a temperature reduction of 0.4 ± 0.2 °C across more than half of the urban area and shows limited sensitivity to synoptic circulation types and terrain settings, requiring only (1) stable wind pathways and (2) adequate upwind greening zones. This study provides a scalable spatial strategy for heat mitigation in cities meeting these prerequisites, enriching climate adaptation strategies from a systems-based spatial perspective.
摘要:许多城市大幅扩大了城市树木覆盖面积,但仍继续经历威胁公共健康、基础设施和气候韧性的加剧热应激。相比之下,中国传统村落通过协同的山-水-林框架展示了持久的热韧性,该框架作为一个整体气候调节器发挥作用。基于这一原则,我们针对不同气候区和形态背景下的现代特大城市调整并验证了该降温框架。利用地形引导的风型驱动冷空气平流和上风处绿化,山-水-林框架使超过一半的城市区域温度降低了 0.4 ± 0.2 °C,并且对天气环流类型和地形设置的敏感性有限,仅需要 (1) 稳定的风道和 (2) 充足的上风处绿化区。本研究为满足这些先决条件的城市提供了一种可扩展的热缓解空间策略,从基于系统的空间视角丰富了气候适应策略。
