摘　　要：辽西地区树种单一,阔叶乔木树种尤为缺少。增加树种多样性,改善树种结构是辽西林业建设中急待解决的问题。在半干旱的辽西地区,树种选择的重要依据之一是树种的抗旱性。对蒙古栎、辽东栎、麻栎3种落叶栎树的根系分布、叶片解剖结构和水分生理特性的研究表明,蒙古栎和辽东栎抗旱性差异不大,但都强于麻栎。造林时应优先选择蒙古栎和辽东栎,在立地条件较好的地方可以考虑选择麻栎。<Abstrcat> Tree species are singularity in western Liaoning, and broadleaved arborous tree species are lack in particular. To increase diversity and improve structure of tree species is an urgent issue to resolve in forestry construction in western Liaoning. In semiarid areas of western Liaoning, one of the most important basis for selection of tree species is drought resistance. Results regarding distribution of root systems, anatomical structures of leaf and water physiological characteristics of 3 deciduous oaks like Quercus mongolica, Q. liaotungensis and Q. acutissima indicated that: drought resistance of Quercus mongolica and Q. liaotungensis differed little but both was better than Q. acutissima. Q.mongolica and Q. liaotungensis should be chosen firstly in afforestation, and Q. acutissima might be chosen for places with good site conditions.
