摘　　要：为探讨科尔沁沙地造林树种对干旱环境的适应能力,采用控水法观察糖槭、五角枫、大叶白蜡、桃叶卫矛和稠李5种科尔沁沙地典型造林乔木的叶片形态,测定相对水分亏缺、丙二醛、可溶性糖和相对电导率的变化,运用隶属函数值法进行植物抗旱性综合评价。结果表明:5种乔木的综合抗旱性排序为桃叶卫矛>五角枫>大叶白蜡>糖槭>稠李;桃叶卫矛和五角枫抗旱性较强,更适合在科尔沁沙地困难立地进行野外造林。In order to detect the drought adaptability of afforestation tree species in sandy land of Horqin,leaf morphology,the relative water deficit,malondialdehyde content,soluble sugar content,and change of relative electric conductivity were measured,and Comprehensive drought resistances of tree species were evaluated by the membership function method.The results showed that:the rank of five tree species in drought resistance was as following:Euonymus maackii>Acer mono>Fraxinus rhynchophylla>Acer saccharum>Prunus padus.Euonymus maackii and Acer mono had stronger drought resistance than the otherss,and were more suitable for afforestation in difficult site field of Horqin sandy land.
