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.
