摘　　要：蒺藜科植物为草本或灌木。全世界约28属,290余种,分布于热带、亚热带与温带。我国沙漠地区有5属28种及5个变种。该科内许多植物为荒漠地区的优势种或建群种,在荒漠植被中占有一定的位置。其中,霸王和白刺属的一些植物属亚洲中部区系成分,以旱生性质为特征,在很大程度上代表了亚洲中部干旱植被的特色。In this paper, the morphcytological structures of ten species of Zygophyllaceae plants were determined, they are: Peganum harmala, Nitraria schoberi, No sibirica, N.sphaerocarpa, N.roborowskii, N.tangutorum, Tribulus terrestris, Zygophyllum fabago, Z. fabagoides, and Z. xanthoxylum. They are all planted in the Turpan Desert Botanical Garden and were all introduced from other areas of Xinjiang. The result of determination shows that:N. sphaerocarpa, No robor- owskii, N. tangutorum and Z. xanthoxylum which are the species of the Central Asia floristic area, have more xeromorphic structures. They take the xeromorphism as their character; P. harmala, Z. fabago and Z. fabagoides are the species of the Mediterranean floristic area. Both P. harmala and Z. fabagoides are xeroplastic species, the former has a wide distribution range, the later only distributes in a small area. As same as the other 3 species plants which were determined in this research, Z. fabago also tend towards the mesophilous plant. The result also shows that there is not important difference between N. sibirica and N. schoberi.
