摘  要：
选取屋顶绿化中9种常见的庭院观赏阔叶植物为试验材料,对其叶片微观解剖结构进行了观察,利用隶属函数法对这9种阔叶植物进行抗旱性综合评价,并对10项叶片解剖结构指标与抗旱性的关联度进行了分析。结果显示:9种阔叶植物抗旱性顺序由强到弱依次为迎春、花椒、连翘、红刺玫、红叶李、蜡梅、紫藤、南天竹、月季;10项叶片解剖结构指标中上表皮厚度、栅栏组织厚度和叶片厚度与抗旱性的关联度最高。综合分析表明,不同植物叶片解剖结构差异显著,上表皮厚度、栅栏组织厚度和叶片厚度可作为筛选屋顶绿化抗旱植物的辅助指标。

摘  要：
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 10anatomical 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.
