摘　　要：本文测定了柽柳属7个种对NaCl、Na_2SO_4、NaHCO_3、Na_2CO_3等4种盐类的耐盐极限、同化枝细胞液浓度、同化枝灰分含盐量;调查了7种柽柳的造林成活率及第2年保存率。应用主成分分析法对7种柽柳的耐盐性进行了数量化研究。7种柽柳耐盐性强弱的顺序为:短穗柽柳>甘肃柽柳>长穗柽柳>多花柽柳>甘蒙柽柳>山川柽柳>多枝柽柳。The maximum resistances of seven Tamarisks to Nacl, Na2SO4, NaHCO3, and Na2CO3were tested and observed, in the meantime , the cytolymph density, ash content of assimilatory branches and survi - val rates in the first two years were also observed. The resistibilities to salts of seven Tamarisks were quantitively studied by using PCA method and can be ranked the order: Tamarix laxa > T. kansuensis > T. elongata. > T. hohenackeri > T. austromongolica>T. arceuthoides>T. ramosissima.
