中文摘要 研究街道走向、高宽比及行道树三维绿量对街道空间微气候的作用机制,有助于城市街道的合理规划布局,对缓解城市热岛效应,提高行人热舒适度具有重要意义。文章借助ENVI-met软件,运用正交实验设计方法,比较不同街道人行空间的热舒适差异,分析行道树三维绿量对生理等效温度(PET)值的影响。结果表明:1)街道高宽比和三维绿量在上午对热舒适均无显著影响;中午和傍晚则对热舒适具有显著影响,且热舒适随三维绿量和街道高宽比的增大而提高,其中街道高宽比对热舒适的作用较为强烈。2)随三维绿量的增加,PET值的增长逐渐减缓;当三维绿量达到2 864.07 m³时,PET值几乎不再增加。3)夏季高温时段,在街道高宽比为0.25的街道中,种植三维绿量在317.35~2 864.07 m³的行道树可以使热舒适达到温暖等级。因此,在热带城市,处于夏季高温的街道环境中,单一环境因素的调整无法充分满足热舒适的改善需求,而行道树绿量和街道高宽比两个因素的综合调控可以最大程度优化人行空间的热舒适性。

英文摘要 The study of the mechanisms of action behind street orientation, height-width ratio and living vegetation volume of street trees on the microclimate of street space is helpful for developing the rational planning and layout of urban streets, alleviating the urban heat island effect and improving the thermal comfort of pedestrians. With ENVI-met software, the paper compares the differences of different street pedestrian spaces in thermal comfort using orthogonal design method, and analyzes the effect of the living vegetation volume of street trees on PET values. The results show that:1) In the morning, the street height-width ratio and the living vegetation volume have no significant effect on thermal comfort, but have a significant impact at noon and in the evening, and the thermal comfort increases with the increase of the living vegetation volume and the height-width ratio, among which the height-width ratio has a stronger effect on thermal comfort; 2) With the increase of the living vegetation volume, the growth of PET value gradually slows down; when the living vegetation volume reaches 2 864.07 m³, the PET value almost ceases to increase; and 3) During the high temperature period in summer, the trees with the living vegetation volume between 317.35 and 2 864.07 m³ can make the thermal comfort reach the warm level in the street with the height-width ratio at 0.25. In this sense, in a tropical urban street environment with summer high temperature, adjusting a single environmental factor cannot fully meet the need for improved thermal comfort, and the integrated regulation of the living vegetation volume of street trees and the height-width ratio of street could maximize the pedestrian space's thermal comfort.
