在对昆明市区16座立交桥进行普查的基础上,归纳总结出该市区立交桥绿化中主要的3种绿化模式,即乔+灌+草型;灌+草型及单纯地被型。运用唐东芹等人提出的园林植物景观评价AHP(层次分析法)模型与方法,对此3种绿化模式的景观效益进行综合评价,结果表明,乔+灌+草型、灌+草型绿化模式的景观效益价值远大于单纯地被型,而乔+灌+草型的景观效益略大于灌+草型,前2类绿化模式的观赏价值也较高。
Based on the census of 16 overpasses in Kunming district, the paper summarizes the three main greening modes in the urban greening overpass, that is, Qiao + Irrigation + Grass Type; Irrigation + Grass Type and Simple Ground Type. According to AHP (Analytic Hierarchy Process) model and method proposed by Tang Dongqin and others, the landscape benefits of the three greening modes were comprehensively evaluated. The results showed that the landscape benefits of Qiandan + irrigation + grass type and irrigation + grass type greening mode The value of landscape benefits is much larger than that of pure grass, while the landscape benefits of Qiao + Guan + grass are slightly larger than that of irrigation + grass. The ornamental values of the first two types of greening patterns are also higher.
