中文摘要	通过测定苦豆子、苦马豆、骆驼蓬、钠猪毛菜和盐爪爪5种典型荒漠植物的相对含水量、叶绿素含量、电导率、比叶面积、根冠比和蒸腾速率6项抗旱指标,运用隶属函数值法对5种植物的综合抗旱适应性进行定量评价.评价结果表明,5种荒漠植物的综合抗旱性强弱顺序为:盐爪爪＞钠猪毛菜＞苦马豆＞苦豆子＞骆驼蓬.在此基础上运用灰色关联度分析方法,对5种植物的抗旱性和6项抗旱指标的相关性进行分析.关联度分析结果表明,各项抗旱指标与平均隶属函数值的关联顺序为:蒸腾速率＞相对含水量＞电导率＞比叶面积＞根冠比＞叶绿素含量,即蒸腾速率、相对含水量和电导率是5种植物抗旱性评价的重要指标.
英文摘要	Applying the method of subordinate function, six physiological drought resistance indexes of five typical desert plants were measured and a quantitative evaluation on comprehensive drought resistance of them was given. The results showed that the drought resistant capability of five desert plants decreased in order of Kalidium foliatum, Salsola nitrarkt Pall, Sphaerophym salsula, Sophora alopecuroides L. and Peganum harmala L.. Using the method of grey correlative analysis the drought - resistance and its relationship with drought - resistance indexes of five desert plants were researched on this basis. The results of grey correlative degree analysis showed that the related order about appraise indexes of drought resistance and average subordinate function values was; transpiration rate > relative water content > electric conductivity > specific leaf area > root shoot ratio > chlorophyll content. Transpiration rate, relative water content and electric conductivity can be regarded as the important indexes of drought resistance evaluation of five desert plants.
