- 摘要:
- 为了提高屋顶绿化植物配置的科学性，筛选降温增湿能力强的绿化植物，对成都市屋顶绿化适应性强的25种木本植物进行了叶片蒸腾速率的测定。结果表明：彩叶植物的降温增湿能力高于绿叶植物，差异极显著（Sig.=0.002）；落叶植物显著高于常绿植物（Sig.=0.022）；乔木显著高于灌木（Sig.=0.030），观花植物显著高于观叶植物（Sig.=0.022），其中龙牙花、木芙蓉、龙爪槐、紫叶李、贴梗海棠、海栀子等木本植物具有较高的蒸腾速率，降温增湿能力强，可为成都市屋顶绿化植物选择提供参考。
- Abstract:
- In order to raise the roof greening plant configuration of the scientific nature，through comparing and analyzing the temperature-lowering and humidity-raising capacity of roof greening woody plants in Chengdu，transpiration rates per leaf area of 25 kinds of woody plants were studied.The results showed that the temperature-lowering and humidity-raising capacity were different significantly among different species，and Erythrina corallodendron，Hibiscus mutabilis，Sophora japonica.var.penclla，Prunus cerasifera var.atropurpurea，Chaenomeles lagenaria，and Gardenia jasminoides var.radicana had higher transpiration rate than the others.Among different groups，coleus species had higher effects than that of green species(Sig.=0.002)，arbors were significantly higher than that of shrubs(Sig.=0.030)，and deciduous species were significantly higher than that of evergreen species(Sig.=0.022)，while foliage plants were lower than that of ornamental flower species.
