【摘要】 为分析7种旱生植物的水分参数，综合评价它们的抗旱性，为干旱地区的荒山造林提供科学依据。利用P-V技术对细枝岩黄芪、白刺、梭梭、霸王、沙拐枣、沙木蓼和柽柳7种旱生植物的水分参数进行研究对比，运用隶属函数法和主成分分析法综合评价这7种旱生植物的抗旱性。结果表明，7种旱生植物的抗旱性可以分为三类：霸王、梭梭和白刺的抗旱性最强；沙拐枣和柽柳的抗旱性中等；细枝岩黄芪和沙木蓼的抗旱性最差。更多还原

【Abstract】 To analyze the water parameters of seven xerophytes and comprehensively evaluate their drought resistance, providing a scientific basis for afforestation on barren hills in arid areas, the P-V technique was used to study and compare the water parameters of seven xerophytes, namely, Astragalus complanatus, Nitraria sibirica, Haloxylon ammodendron, Zygophyllum xanthoxylum, Calligonum mongolicum,Polygonum atrorubens, and Tamarix chinensis. The membership function method and principal component analysis were employed to comprehensively evaluate the drought resistance of these seven xerophytes. The results indicated that the drought resistance of the seven xerophytes could be classified into three categories:Zygophyllum xanthoxylum, Haloxylon ammodendron, and Nitraria sibirica had the strongest drought resistance; Calligonum mongolicum and Tamarix chinensis had moderate drought resistance; and Astragalus complanatus and Polygonum atrorubens had the weakest drought resistance.更多还原
