摘要(Abstract)：

本文调查了四川省广汉市行道树的现状,该市行道树主要以黄葛树(Ficus lacor)和垂柳(Salix babylonica)为主,种类单调,道路绿化覆盖率极低。因此,在对城市绿地系统进行规划时,提出了行道树种的选择原则,并规划了桢楠(Phoebe zhennan)、香樟(Cinnamomum camphora)、广玉兰(Magnolia grandiflora)、阴香(Cinnamomum burman-ni)、银木(Cinnamomum septentrionale)等8种为基调树种,雪松(Cedrus deodara)、栾树(Koelreuteria paniculata)、鹅掌楸(Liriodendron chinense)、蓝花楹(Jacaranda acutifolia)、峨眉含笑(Magnolia wilsonii)、银杏(Ginkgo biloba)、金丝垂柳(Salixsp.)等19种为骨干树种。根据行道树种的主导功能目标,提出了行道树的配置模式,如观赏型、环保型和文化休闲型等,以体现城市区域特色。
The current situation of street trees applied in Guanghan county,Sichuan province,were investigated in this paper.the result has indicated that Ficus lacor and Salix babylonica are the main street trees among the applied species,and that the coverage of trees is very low.So the basic principle of the street tree design was suggested in the planning of urban greening system.The eight tree species such as Phoebe zhennan,Cinnamomum camphora,Magnolia grandiflora,Cinnamomum burmanni and Cinnamomum septentrionale are planned as basic street trees,and the nineteen tree species such as Cedrus deodara,Koelreuteria paniculata,Liriodendron chinense,Jacaranda acutifolia,Magnolia wilsonii,Ginkgo biloba,and Salix sp.are selected as main street trees.Furthermore,the collocation patterns of street trees,for example,patterns of landscape,environment protection and culture,are put forward in forest structure design according to the leading function of trees and the urban feature.
