Abstract The anatomical structures of assimilating shoots of Calligonum mongolicum from three geographic populations of different habitats under precipitation gradient from east to west along the Hexi Corridor, were observed and measured under optical microscope with the paraffin-section method. The 15 drought resistance indexes such as the diameter of assimilating shoots and the thickness of cuticles were measured, the variance, correlation and principal component analysis were used in the analysis of the indexes, the drought resistances of different populations were evaluated by membership function. The results showed that assimilating shoots of the populations tested had the typical xeromorphic structure. this was the result of long term adaptibility to the arid environment of plateau. 14 indexes had significant difference in the populations (p<0.01), and 4 typical xeromorphic indexes which were thickness of cuticles, thickness of air chamber, the ratio of fibre cluster numbers under epidermal cell to diameter of assimilating shoots and the ratio of the number of small vascular bundle to diameter of assimilating shoots were selected by principal component analysis. According to the comprehensive evaluation of drought resistance of C. mongolicum, drought resistance was enhanced with the loss of the moisture condition with the order of Jiuquan > Zhangye > Wuwei.
