摘要城市室外热舒适性是衡量城市生活质量的重要指标。本文以新加坡中央商务区的一条城市街道为研究对象，重点研究了街道朝向、高宽比和植被等设计变量对街道室外热舒适性的影响。提出了一种多点综合野外观测方法，并用该方法验证了一个广泛使用的计算机软件整体小气候模拟系统。研究的意义在于获得了多个测点的小气候参数的真实现场数据，量化了街道设计参数对室外热舒适性的影响。研究发现，在新加坡，下午西北-东南方向的街道比东北-西南方向的街道更有压力，H/W为3可以被认为是室外热舒适性的阈值。论文的结论是..。
AbstractOutdoor thermal comfort in urban spaces is an important indicator of the quality of life in an urban environment. This paper attempts to investigate the effect of street design on outdoor thermal comfort in an urban street in the central business district in Singapore, focusing on the design variables of street orientation, height-to-width ratio (H/W), and vegetation. A comprehensive field measurement with multiple points is presented and used to validate a widely used computer software holistic microclimate modeling system. The significance of the research is that real field data from multiple measurement points on microclimate parameters are produced and the effect of street design parameters on outdoor thermal comfort is quantified. It is found in the paper that the NW-SE oriented street is more stressful than the NE-SW street in the afternoon in terms of thermal comfort in Singapore, and that a H/W of 3 can be considered a threshold with respect to outdoor thermal comfort. The paper concludes ...
