摘要
根据沙柳、油蒿、杨柴和柠条的自然地理分布、生境和生物学特性以及对模拟降水量变化的响应结果进行主分量分析和聚类分析 ,将它们划分为 1个落叶灌木植物功能型和 3个落叶灌木植物功能亚型 :柠条为旱生落叶灌木植物功能亚型 ;油蒿和杨柴为旱中生落叶灌木植物功能亚型 ;
Salix psammophyila,Artemisia ordosica,Hedysarum mongolicum and Caragana intermedia,based on their natural geographical distribution,hbitats and biological characteristics,and the results of principal component analysis and cluster analysis on their responses to simulated precipitations,could be classified into one type of deciduous shrub function with three sub-types:C.intermedia belongs to xeric sub-type,A.Ordosica and H.Mongolicum belong to xeric-mesophytic sub-type,while S.Psammophyila is mesophytic sub-type.
