中文摘要	中国阿勒泰地区是北半球中纬度地区的特殊区域,与俄罗斯、哈萨克斯坦、蒙古接壤,境内有平原、沙漠和山地三大地貌特征。2014-2016年,我们先后3次对阿勒泰地区爬行动物资源开展了实地调查,共采集到392号爬行动物标本。经鉴定隶属1目6科16种,结合文献资料,共计1目8科23种,均为古北界物种,其中中亚型17种,古北型6种,表现出中亚亚界与欧洲-西伯利亚亚界间的过渡性质。爬行动物Shannon-Wiener多样性指数、Simpson优势度指数随海拔分布呈带有一个中峰的低海拔高原格局,在第2海拔段(500-600 m)达到峰值;均匀度指数总体呈现递增格局,第15海拔段(1,800-1,900 m)达到最大值;丰富度则呈现一种波动的递减格局,峰值在第10海拔段(1,300-1,400 m)。3种环境因子对这种格局的独立解释力较低,但综合作用的解释力较强,其中海拔与年均温这两个因子的综合作用对物种多样性影响程度最大。
英文摘要	The Altay Prefecture in China, which shares international boundaries with Kazakhstan, Mongolia and Russia, is a special area in the mid-latitudes of the Northern Hemisphere. The diverse landform of this area encompasses mountainous terrain, vast plains and desert lands. We conducted three expeditions from 2014 to 2016 to survey reptiles of the Altay Prefecture. We actively searched for reptiles using spotlighting at night. We collected a total of 392 specimens, which we identified as 16 species belonging to six families of the order Squamata. Combined with previous literature, the number of reptile species in this region is now 23 representing eight families of the order Squamata. All these species belong to the Palearctic ecozone, including 17 mid-Asia species versus six Palearctic species. From the geographical view, this region is a transitional zone between Euro-Siberian and Central-Asiatic regions. Next, we assessed how reptile species diversity correlated with elevation, which corresponded with changes in environmental factors in this region. We found that the Shannon-Wiener diversity index and Simpson dominance index showed a pattern of low-elevation plateaus with a mid-elevation peak, the Pielou evenness index showed a pattern of increasing, and the richness showed a pattern of decreasing. The peak values of Simpson dominance index and Shannon-Wiener diversity index were observed in Group 2 (500-600 m). The Pielou evenness index peaked for Group 15 (1,800-1,900 m), and richness peaked for Group 10 (1,300-1,400 m). The three environmental variables (altitude, annual mean temperature and annual precipitation) only weakly explained the observed patterns of diversity, richness and evenness, but their combined explanatory power was stronger. In fact, the combination of altitude and annual mean temperature best explained the observed patterns in diversity, richness and evenness of reptiles in the Altay Prefecture.
