摘要:

园林树木遮荫不仅能够提高热舒适性,为空间使用者营造出舒适宜人的环境,也能缓解城市热岛效应,调节局部 小气候 。在对园林树木遮荫功效相关影响因素如结构特征、生理功能、种植位置、气象因子和栽培管理措施等进行归纳总 结的基础上,简要阐述了不同树种遮荫功效的评价方法及其研究成果 。针对目前的研究短板和存在问题提出了研究展望, 以更加全面系统地探究树木遮荫的机理,进 一步拓展研究视角,为园林树种选择和科学配置提供参考借鉴 。 同时也提出园 林树木遮荫设计的建议,不仅要做到适地适树,以充分发挥园林树木的遮荫潜能,也要正确处理树木遮荫与景观营造的关 系,将树木的遮荫设计与其他景观营造策略相结合。
