为适应和减缓气候变化而设计城市景观已成为当代城市发展中的一个重要课题。然而，在现有的城市景观实践中缺乏基于气候的设计知识和技术，对实施提出了挑战。因此，本文介绍了一种以气候为主导的城市景观设计方法，以克服这种困境。这一方法注重成果，综合使用了小气候、热舒适度以及地理信息系统建模和模拟工具。通过情景比较，本文对马来西亚怡保地区的小气候和热舒适性进行了评估和设计。结果表明，遮阳是决定室外热舒适度的最重要因素，因此，在热带气候主导的规划中，有效的行道树种植是一项必不可少的措施。此外，本研究发现，与其他炎热地区相比，风并没有积极影响热舒适，这是由于在特定时间的场地特性。总之，在城市设计中发展以气候为主导的景观和绿化是城市降温和可持续城市发展的功能举措。此外，在城市景观设计中应用建模和模拟方法可以减少在实践中失败的可能性，从而有希望提高城市应对气候变化的效率。
ABSTRACT Designing urban landscapes for climate change adaptation and mitigation has been highly promoted in contemporary urban development. However, the lack of climate-based design knowledge and techniques in existing urban landscape practice has challenged the implementation. This paper, therefore, introduced a climate-led urban landscape design method to overcome such a dilemma. This approach was results-oriented, and it adopted an integrated use of microclimate, thermal comfort, and GIS modelling and simulation tools. Through the scenarios comparison, this paper has assessed and figured out efficient landscape designs for microclimate and thermal comfort improvement in Ipoh, Malaysia. It showed that shading most determined outdoor thermal comfort, making effective street tree planting an essential measure in the tropical climate-led plan. Besides, this study found that wind did not positively influence thermal comfort due to site characteristic at a particular time, in contrast with other hot regions. In conclusion, developing climate-led landscape and greenery in urban design is a functional initiative for urban cooling and sustainable urban development. Furthermore, the application of modelling and simulation methods in urban landscape design can reduce the possibility of failure in practice, thereby promising urban efficiency in response to climate change.
