摘要：不同土壤水分条件下,对乌兰布和沙漠地区9种灌木品种的抗旱生理指标进行测定的基础上,采用聚类分析和隶属函数值法对9种灌木的抗旱性进行综合评价.结果表明:在不同的土壤水分条件下,柠条的水分饱和亏、束缚水含量、相对电导率和叶绿素含量高于其它灌木;通过聚类分析将9个灌木试验材料聚为3类,强抗旱灌木为沙木蓼、柽柳、柠条;中抗旱灌木为沙拐枣、白刺、花棒;弱抗旱灌木为籽篙、乌柳、河柳;采用隶属函数值法对9种灌木抗旱性进行综合评价,其9种灌木的抗旱性由强到弱顺序依次为:柠条>柽柳>沙木蓼>沙拐枣>花棒>白刺>籽蒿>乌柳>河柳.
The drought resistant indexes of nine shrubs in Ulanbuh Desert were measured under differ-ent soil moisture.Their comprehensive analyses on drought resistance were conducted with cluster analysis and subordination function.The results indicated that under different soil moisture,water deficit,boung water,relative electric conductivity and chlorophyll content of Caraganakorshinskii were higher than other shrub.Nine experiment materials were clustered into 3 categories.Atraphaxis frutescens,Tamarix ho-henackeri and Caragana korshinskii belonged to the strong drought-tolerant shrub.Calligonummongoli-cum ,Nitrariatangutorum and Hedysannnscoparium belonged to the medium drought-tolerant shrub;Ar-temisia sphaerocephala ,Salixcheilophil and Salixchaenomeloides belonged to the weak drought-tolerant shrub.The drought resistance of nine shrub was evaluated with the subordinate function values analysis, the drought resistance order of the nine shrubs was as follows：Caragana korshinskii Kom.＆gt; Tamarix hohenackeri Bunge ＆gt;Atraphaxis frutescens ＆gt; Calligonum mongolicum Mattei.＆gt; Hedysarum scopari-um ＆gt; Nitraria tangutorum Bobr＆gt; Artemisia sphaerocephala Krasch＆gt; Salix cheilophila ＆gt; Salix chaenomeloides.
