摘要
研究道路绿化植物的种类应用与配置模式,为改善城市景观及人居环境质量提供依据。以河南省济源市城区14条主道路为研究对象,实地调查并比较分析了道路断面上不同绿带内应用的植物种类与配置模式,为城市绿化管理工作提供数据参考。结果表明:济源市城区主道路应用植物共43科63属71种,其中有乔木38种,以大叶女贞、国槐(市树)、毛白杨、垂柳、法桐为主;灌木26种,以红叶石楠、紫薇(市花)、小叶女贞、大叶黄杨、月季为主;草本5种,以麦冬、鸢尾、高羊茅为主;藤本和竹类植物各1种。植物配置模式共136种,其中单层结构的乔木模式最多,有23种;其次是双层结构的乔木—草本模式,有19种。单双层结构模式分别占行道树绿带、路旁绿带全部植物配置模式的80.0%、70.5%,有较大改造提升空间。整体上,济源市城区主道路绿化植物种类丰富,配置模式多样;但多数植物应用频次较少,常见植物应用较多;部分路段绿化垂直结构单一,缺乏层次感。故建议适量增加观赏型植物的应用频次,改造和丰富结构层次,提高景观效益和生态效益。
Road greening and plant configuration are the reflection of city image and the quality of human settlement environment. Taking 14 main roads in Jiyuan City of Henan Province as the research object, this paper investigated the plant species and configuration mode in different green belts on the cross section of road, and analyzed the current situation of greening and the characteristics of plant configuration. The results showed that there were 43 families, 63 genera and 71 species of main road plants in Jiyuan city, of which 38 species were arbors, and the most applied plants were Ligustrum lucidum, Sophora japonica and Populus tomentosa, Salix babylonica and Platanus orientalis. In 26 species of shrubs, the most applied was Photinia×fraseri, Lagerstroemia indica, Ligustrum quihoui, Buxus megistophylla and Rosa chinensis. Besides, the most applied herbs were Ophiopogon japonicus, Iris tectorum and Festuca elata. There were 136 plant arrangement patterns, including 23 kinds of single-layer patterns, and 19 kinds of double-layer patterns. The above two patterns jointly took 80.0% and 70.5% respectively out of the whole patterns in the road tree green belt and roadside green belt. On the whole, the main road greening plants in the urban area of Jiyuan city are abundant in species and diverse in configuration patterns, but some minor plants have narrower applications and lack of application of new varieties, with single vertical structure and lack of sense of hierarchy. It is suggested that the frequency of ornamental plants should be increased;the structure should be enriched, and the landscape and ecological benefits should be improved.
