摘  要:
实地调查了武汉市绿色廊道501个路段(绿带或河流)共1 363个群落。共记录有植物142种,分属58科110属,其中蔷薇科、木犀科、禾本科、木兰科、柏科植物为常见。乡土种占52.8%,外来种占47.2%。乔∶灌∶草比例约为1.00∶1.58∶0.60;木本植物中常绿落叶比接近1∶1。高位芽植物占绝对优势。乔木中应用频率最高的是樟树,灌木中应用频率最高的是红继木。1 363个群落分属3个植被型组、12个植被型、54个群系、359个群丛,以落叶阔叶林和常绿阔叶林植被型为主,群系以樟树群系最为常见,其次是广玉兰群系和桂花群系。垂直结构上,乔木单层结构群落占绝对优势(56.05%),乔-灌复层结构群落仅占18.34%。武汉市绿色廊道中生长不良的植物主要是喜光、喜酸性土、喜肥沃和抗性弱的植物。

摘  要:
1363 communities of greenways including road greenways,river greenways and green belt were surveyed based on field investigation in Wuhan City.142 plant species belonging to 58 families and 110 genera were recorded.Rosaceae,Oleaceae,Gramineae,Magnoliaceae and Cupressaceae are dominant families.The propotion of local species is 52.8% and that of exotic species is 47.2%.The ratio of tree,shrub and herb are 1.00∶1.58∶0.60,and the ratio of ever-green and deciduous species is nearly 1∶1.The phaenerophyte is absolutely dominant life-form.The applied frequency of Camphor tree [Cinnamomum camphora(L.)] is the highest among tree species,and that of Loroprtalum chinensis is the highest in shrub species.Evergreen broadleaved forest and deciduous broadleaved forest are dominant vegetation types.Regular forests with arbor are main types.Light favored plants,acidophilous plants,eutrophyte plants and weak-resistant plants grow poorly.
