摘要
全球变暖已是不争的事实,而且不可能完全被阻止。城市绿地作为城市结构中的自然生产力主体,在缓解城市热岛、调节城市气候和协助城市应对未来气候变化中扮演着极其重要的角色。如何优化城市绿地空间布局,从而实现城市绿地降温效应的最大化,更有效地应对城市气候变化,已经成为城市绿地布局规划与研究的热点与难点问题。论文从城市绿地降温效应实地观测、城市尺度城市绿地与城市热岛关系、城市绿地降温效应模型模拟和城市绿地降温效应的心理和社会意义4个角度,对国内外相关研究进行了评述,并在此基础上总结了目前城市绿地降温效应研究存在的主要问题,进而提出了该领域未来研究的方向,以期为深入研究城市绿地的降温效应、更好地规划和设计绿地提供重要的借鉴和参考。
Since the global warming is now accepted by the majority of the scientific community, and it is unlikely that these effects can be fully prevented, it is essential that related strategies are identified early so they can be implemented to adapt to such change. Urban green spaces are the important green infrastructure in a city. Urban green space can reduce the surface water runoff and provide the cooler microclimates as well as other environmental functions, therefore, it will play an important role to mitigate the urban heat island, and cope with future climate change. However little is known about the quality and quantity of the green spaces required and what kind of the green space spatial pattern will be the best. Consequently, how to plan and design the green spaces in different spatial scales is always a key topic. This paper examined research progress in the field of green space cooling effect, identified existing problems, and accordingly tried to explore the potential of urban green space in adapting cities to climate change in the future.
