大道隔离带植物配置合理的规划设计满足交通规范做出贡献，还会提升整个城市的生态建设层次，甚至可以带来一些经济收益。 本文主要通过采用实地勘测，现场统计的调查方式，对吕梁大道隔离带栽种植物的种类，数量，生长状况和配置方式等进行统计。并根据《城市绿地设计准则》《城市道路绿化规划与设计规范》等规定，对吕梁大道隔离带进行评估。 通过调查得出结论，吕梁大道隔离带植物现有7科7属7种，配置方式主要为列植，丛植。种植间距，高度能基本符合城市道路绿化规范。同时发现隔离带配置存在的主要问题为：植物种类较少，配置层次简单，没有形成多样的景观效果。 并针对这些问题提出优化建议，植物种类方面可增加常绿裸子植物，以及观干，观枝，观果植物的应用；植物配置方面提出“小乔木+灌木+花卉+地被”等多种不同区域适用的配置方式；还可以结合园林其他构成要素“雕塑、小品”增加景观效果。 关键词：吕梁大道；植物配置；隔离带；道路绿化 Abstract As the main road of Lvliang Avenue, the reasonable planning and design of Lvliang Avenue will make contributions to meet the traffic standards, improve the ecological construction level of the whole city, and even bring some economic benefits. This paper mainly through the use of field investigation, field statistics survey, statistics of the Lvliang Avenue isolation zone planted plants, the number of growth and configuration of the way. According to the "Urban Green Space Design Criteria", "Urban Road Greening Planning and Design Code" and other provisions, the Lvliang Avenue isolation belt was evaluated. According to the investigation, there are 7 families, 7 genera and 7 species of plants in the isolation zone of Lvliang Avenue, and the main arrangement modes are planting and cluster planting. Planting spacing and height can basically meet the urban road greening standards. At the same time, it is found that the main problems of the isolation zone configuration are: less plant species, simple configuration levels, and no diverse landscape effects. Finally, this paper proposes an optimization scheme for these problems. In terms of plant species, the application of evergreen gymnosperms, as well as plants that observe stem, shoot and fruit can be increased. In terms of plant configuration, "small trees + shrubs + flowers + ground cover" and other suitable configuration modes for different regions are proposed. You can also combine other elements of the garden "sculpture, sketch" to increase the landscape effect.
