摘　　要：为了探索适合进行屋顶绿化的落叶乔木,对其抗旱性进行早期评价。选取屋顶绿化试验区中的8种常见的庭院观赏落叶乔木为试验材料,观察并统计其10项叶片解剖结构指标,利用模糊数学法中的隶属函数法,对这8种落叶乔木进行了抗旱性综合评价。结果显示:其抗旱性由强到弱的顺序为:构树、黄连木、白榆、刺槐、枣树、臭椿、火炬树、白蜡。利用灰色系统理论,对10项叶片解剖结构指标与抗旱性的关联度进行了分析,探讨其在植物抗旱过程中所起到的作用。We chose eight kinds of common deciduous trees in roof greening test region to explore the adapted plants in roof greening and evaluate their drought resistance. We observed and statistically analyzed ten anatomical structure indexes of leaves for comprehensive evaluation on drought resistance by applying subordinate function. The drought resistance capabil- ity order from strong to the weak is Broussonetia Papyrifera , Pistacia Chinensis Bunge , Ulmus pumila , Robnia pseudoaca- cia, Ziziphus jujube, Ailanthus altissima （ Mill. ） Swingle and Rhus typhina. The correlation of drought resistance and ana- tomical structure indexes was analyzed with grey correlative analysis.
