摘　　要：为了探讨适宜于北票半干旱气候地区的抗旱树种水分生理因子与立地因子,确定树种抗旱性强弱,进行了树种水分生理测定和数量化分析,结果表明,该地区的抗旱树种由强到弱的顺序为山枣、油松、樟子松、山杏、黄栌、桧柏、侧柏、胡枝子、紫穗槐、刺槐、沙棘、锦鸡儿和小钻杨。依据数量化理论Ⅰ数学计算方法,探讨了油松优势平均高与立地条件多元回归关系式,为这一地区的生态造林提供有力的支撑。Water physiological factors and site factors of resistant species which are suitable to be planted in semiarid climate of Beipiao area were discussed.Cold resistance of species were determined.Water physiology and quantitative analysis of species were conducted.Result shows that the descending order of resistant species in this area is Ziz-iphusjujuba Mill.var.spinosa,Pinustabulaeformis,Pinussylvestris var.mongolica,Prunussibirica L,Cotinus coggygria ,Sabina chinensis ,Platycladus orientalis ,Lespedeza bicolor ,Amorpha fruticosa ,Robinia pseucdoaca-cia,Hippophae rhamnoides,Caragana microphylla,Populus xiaozhuanica.Multiple regression relationship be-tween average height & site conditions of Pinustabulaeformis based on mathematical calculation method of Quanti-tative theory Ⅰwas discussed ,which provides strong support for this region’s ecological forestation.
