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...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。展开更多
