摘要
为了探究行道树的微气候调节能力,以肇庆市城东新区部分城市主干道为研究对象,通过实地调查和观测,统计分析行道树株高、冠高、枝下高等生物学特性,研究其对温度、湿度、太阳辐射强度等微气候的调节作用。并进一步采用RayMan Pro 3.1计算出热舒适性指标,以此为依据评价热舒适性,分析行道树与热舒适性的相关性及其对行人热舒适性的影响。结果表明,从改善热舒适性的角度出发,树种间的生物学特性与树木遮荫能力和调节微气候能力密切相关。细叶榕、非洲楝、天桃木、小叶榄仁、菠萝蜜为调节微气候能力良好的树种,树体高大、树冠宽大浓密的行道树能更好发挥遮荫性能并调节道路空间微气候,有效提升行人的热舒适性水平。
In order to explore the microclimate regulation ability of street trees,with part of urban main roads in Chengdong New District of Zhaoqing City as the research object,the biological characteristics of street tree plant height,crown height and branch height were analyzed,and the regulation effect of temperature,humidity and solar radiation intensity was studied.RayMan Pro 3.1 is further used to calculate the thermal comfort index,based on which the thermal comfort is evaluated,and the correlation between street trees and thermal comfort and its influence on thermal comfort were analyzed.The results showed that the biological characteristics of tree species are closely related to tree shade ability and microclimatic regulation from the perspective of improving thermal comfort.Ficus microcapa,Khaya senegalensis,Mangifera persiciforma,Terminalia neotaliala and Artocarpus heterophyllus are good species for regulating microclimate.The street trees with tall trees and dense canopy can better play the shade performance and adjust the microclimate of road space,and effectively improve the thermal comfort level of pedestrians.
