摘　　要：在天津盐碱地土壤浸提液胁迫条件下。对国外四种草坪草的地上部含水量、脯氨酸和叶绿素含量变化进行了研究。结果表明：随着盐胁迫强度的增加，四种草坪草表现出含水量下降、脯氨酸含量和叶绿素含量上升的变化趋势。经分析认为：在天津盐碱地土壤浸提液胁迫下。四种草坪草均具有一定的抗盐能力。其抗盐能力强弱的顺序是‘回报’>无芒雀麦>‘交战Ⅱ’>‘博士’。In order to select the turf grasses which adapt to be planted on saline-alkali soil in Tianjin, the changes of water content of leaves, proline, chlorophyll content of four kinds of turf grasses species were determined under the salt stress with permeance of Tianjin saline-alkali soil. The results indicated that the general tend was that water content decreased and proline, chlorophyll content inereased along with the inerease of salt stress intensity. It can be concluded by analysis that four turf grasses have certain salt resistant capacities under the salt stress with permeance of Tianjin saline-alkali soil. The capacity to salt resistance is Poa pratensis 'Reward'> Brumus Inerme> Festuca rundomacea' Crossfire Ⅱ'> Loliurn perenne'PHD'
