摘　　要：对黄花草木樨 (Astragalusmelilotoides)、沙生冰草 (Agropyrondesertorum )、高羊茅 (Festucaarundinacea )、沙打旺 (Astragalusadsurgens)、多变小冠花 (Coronillavaria)、无芒雀麦 (Bromusinermis)、黄花苜蓿 (Medicogofalcata )、紫花苜蓿 (Medicagosativa)、紫羊茅 (Festucarubra )、白三叶 (Trifoliumrepens)等 10种草本植物叶片水势值、游离脯氨酸、相对电导率、过氧化物酶活性等进行测定 .结果表明 ,高羊茅、小冠花、沙打旺、紫花苜蓿抗逆性最强 ;其次为白三叶、紫羊茅和无芒雀麦 ;沙生冰草、黄花苜蓿和黄花草木樨的抗逆性最弱 .The flow of water, proline, comparative conductance and the active of peroxide enzyme of Astragalus melilotoides Pall、 Agropyron desertorum Schult、 Festuca arundinacea Schreb、 Astragalus adsurgen、Coronilla varia、Bromus inermis、 Medicogo falcate L、 Medicago sativa、 Festucarubra L、 Trifolium repens L. are measurated. The results show that the resistance of Festuca arundinacea Schreb, Coromilla varia, Astragalus adsurgen, and Medicago sativa are the best, the resistance of Trifolium repens L, Festuca rubra L, Bromus inermis are middle, the resistance of Astragalus melilotoides Pall, Medicogo falcate L. and Agropyron desertorum Schult. are the worst.
