摘　　要：以榛子、荆条、多花胡枝子为试材,通过盆栽控水进行水分胁迫,对不同土壤含水量的各树种的叶片保水力、叶绿素含量、丙二醛含量和游离脯氨酸含量等指标进行测定。对结果数据进行隶属函数分析,结合实物观测,从而得出各树种抗旱性强弱顺序:荆条>多花胡枝子>榛子。With Corylus avellana,Vitex negundo and Lespedeza floribunda as the experimental materials,the physiological properties were tested and analyzed under water stress conditions.The principal drought-resistant physiological indexes of tree species include leafwater-holding,chlorothyll content,MDA content and prolin content. Drought resistance were evaluated by using the formula of vague mathematical jurisdiction,and the drought-resistent ability of three bush species was Vitex negundo>Lespedeza floribunda>Corylus avellana.
