摘要: 古城具有重要的历史文化价值，它蕴含着城市悠久的丰富文化内涵。本文通过对肇庆端州古城的园林植物的资源及其景观现状进行调查和分析，旨在为端州古城景观营造和更新升级提供参考，结果表明：(1) 端州古城园林植物共有76种，隶属40科64属。(2) 端州古城的优势科主要有桑科(Moraceae)、木犀科(Oleaceae)、蔷薇科(Rosaceae)、龙舌兰科(Agavaceae)、紫葳科(Bignoniaceae)。(3) 观叶植物最多，应用最为广泛。观花植物次之。观果植物、观枝植物较少。(4) 乔灌草品种较为丰富。(5) 乡土植物共有39种，占植物总种数的51.3%，外来植物共有37种，占植物总种数的48.7%。同时端州古城也存在着藤本植物相对较少、观花植物品种占比不高、乡土植物占比不高、整体园林植物维护保养有待提高的问题。建议提升垂直绿化景观质量，更多应用开花植物，选取优良乡土植物，控制外来植物的应用，提升养护管理水平等。
