摘　　要：以75种园林树木为试材,通过测定其叶片相对含水量、叶片保水力、束缚水含量及束缚水/自由水,采用隶属函数值聚类分析法对其抗旱性进行聚类分析。结果表明,可将75种园林树木分为4类:第Ⅰ类为抗旱性强的树种,包括桑树(Morus alba L.)等12种;第Ⅱ类为抗旱性较强的树种,包括黄檗(Phellodendron amurense Rupr.)等15种;第Ⅲ类为抗旱性中等的树种,包括杠柳(Periploca sepium Bunge)等20种;第Ⅳ类为抗旱性弱的树种,包括花楸[Sorbus pohuashanensis(Hance)Hedl.]等28种。Using 75 species of landscape trees as materials, the content of relative water, leaf water retention, bound water and bound water/free water of leaves were studied. The drought resistance of landscape trees were clustered by membership function system cluster analysis. The resuhs showed that the 75 kinds of landscape trees could be divided into four groups. The first group is the most drought resistance trees including 12 species such as Morus alba L., etc. The second one is the more drought resistance trees including 15 species such as Phellodendron amurense Rupr., etc. The third one is the medium drought resistance trees including 20 species such as Periploca sepium Bunge, etc. The last one is the weak drought resistance trees including 28 species such as Sorbus pohuashanensis （Hance） Hedl., etc.
