The leaf anatomical structures of 10 drought resistance shrubs were observed and measured by eco-anatomical method.The 15 xeromorphic indices including the thickness of the leaf,upper and lower epidermis,and the palisade and spongy tissue,the diameter of vascular bundle of the main vein and the stoma density and so on.The principal component analysis and membership function analysis were used to analysis the measured data and evaluate the resistances of these species.The results indicated that leaves of the tested shrubs had the typical structures of the xerophytes,which are the results of adapting to the drought environment.15 indices had significant difference among the shrub species at P<0.01 level,and 5 typical xeromorphic indices (leaf thickness,upper epidermis,the palisade tissue thickness,the density of stoma and diameter of vascular bundle of the main vein) were selected by principal component analysis.According to the results of subordinate function value analysis,the drought resistance capability of 10 shrubs was in the order of Ammopiptanthus mongolicus (Maxim.)
