中文摘要：

测定了艾比湖湿地自然保护区3类盐生植物叶片的δ^13C叶片中主要生理指标,结果表明：所调查的3类盐生植物全部属于C3植物;3类盐生植物的δ^13C均值和水分利用效率差异不显著;在3类盐生植物中,稀盐型植物的吸收水分和叶片储水能力最强,而泌盐型植物对盐分胁迫的抗逆能力最大;水分的亏缺导致3种盐生植物叶片的δ^13C、叶片蛋白质、脯氨酸、可溶性糖含量、硝态氮和硝酸还原酶等下降;盐分环境未对泌盐、拒盐类植物产生胁迫性影响,但对于稀盐型植物产生了影响。

英文摘要：

This paper measured the leaf δ13C value and main physiological indices of three types of halophytes in Ebinur Lake Wetland Nature Reserve of Xinjiang. These three types of halophytes were all C3 plants,and had no significant differences in the δ13C value and water use efficiency. Among the three types of halophytes,euhalophytes had the greatest capacity to suck and store water,while recretohalophytes had the greatest endurance against salt stress. Water shortage exerted negative effects on the leaf δ13C value,contents of protein,praline,soluble sugars,and nitrate,and activity of nitrate reductase. The salt condition in the Reserve did not cause stress on the recretohalophytes and pseudohalophytes,but had negative effects on the euhalophytes in their existence.
