花城大道地处广州珠江新城中央商务区，是20余年来广州城市主干道道路绿化发展的缩影。选取花城大道具代表性路段珠江公园段为研究对象，分析和研究其道路绿化从几何式种植到疏林草地，以及“花”主题营造从利用观花乔木到形成多层次观花体系的变迁历程，并对比该路段与临近城市主干道的差异，总结出花城大道道路绿化视野开阔、考虑行人视线的特点，及其所特有的“乔木—灌木—时令花卉—宿根多年生地被”造景模式。以此为基础，得出应在道路绿化建设中贯彻低碳理念，通过长期探索打造高品质的特色道路绿化，政府、设计师、公众多方协同巩固道路绿化成果的启示。

Huacheng Avenue is located in the central business district of Zhujiang New Town, Guangzhou. It is the epitome of the development of avenues in Guangzhou for more than two decades. The road greening of Huacheng Avenue has undergone a change from geometric planting to open forest and grassland, from using flowering trees to building a multi-level flower viewing system. By comparing the differences between its Zhujiang Park section and nearby avenues, it is summarized that the road greening of Huacheng Avenue provides a wide view, considers the sight of pedestrians, and has a unique landscaping mode of "trees, shrubs, seasonal flowers, perennial ground cover" . Based on the above, it is concluded that the low-carbon concept should be implemented in the construction of road greening, and the government, designers, and the public should collaborate to consolidate the achievements of road greening through long-term exploration to create highquality characteristic road greening.
