Abstract: Nine kinds of common deciduous broadleaf plants in roof greening were chosen in this study to observe anatomical structure of their leaves. Based on that, the comprehensive evaluation on drought resistance were analyzed by applying the method of subordinate function, and the correlation of drought resistance and 10 leaf anatomical structure indexes were also studied. The results showed that the drought resistance capability was in descending order was Jasminum nudiflorum, Pericarpium zanthoxyli, Forsythia suspensa, Rosa multiflora var. cathayensis, Prunus ceraifera f. atropurpurea, Chimonanthus praecox, Wisteria sinensis(Sims)Sweet, Nandina domestica and Rosa chinensis. Among the 10 anatomical structure indices, the upper epidermis thickness, palisade tissue thickness and leaf thickness had the higher correlation with drought resistance. Comprehensive analysis showed that the differences of anatomical structure among species were significant, and the upper epidermis thickness, palisade tissue thickness and leaf thickness could be used as aid indices for screening drought resistance tree species for roof greening.
