中文摘要	利用剖胃法对采自内蒙古自治区鄂尔多斯库布齐沙漠的草原沙蜥(Phrynocephalus frontalis)进行食性分析研究。结果表明,该地区的草原沙蜥在8~9月间,以昆虫类动物为主要食物,占全部食物的95.8%。不同性别草原沙蜥取食的食物种类差异不显著,雌雄个体的食物百分率相似性指数及营养生态位重叠值均较大,雄性的食物多样性指数(IFD)及营养生态位宽度(BTN)均大于雌性。成体和亚成体之间以及亚成体和幼体之间食物种类存在差异但不显著,而成体和幼体间的食物种类差异极显著,不同年龄草原沙蜥的食物百分率相似性指数较小,IFD值与BTN值均是成体最大,幼体最小。总有益系数、不同性别的有益系数分别为V_总=22.44%,V_雌=12.76%,V_雄=9.83%,草原沙蜥是对荒漠化草原有益的类群。
英文摘要	We studied the food habits of Toad-headed Lizard ( Phrynocephalus frontalis) collected in the Erdos region of Inner Mongolia using stomach dissection. The results show that Toad-headed Lizard prefers insects which account for 95. 8% of all the food items in the period from August to September. No significant difference in food items was found between male and female although the index of food diversity ( IFD) and the breadth of trophic niche ( BTN) were greater in males than those in females. No any difference in food habits was found between adults and subadults or between subadults and juveniles,however,significant difference was detected between adults and juveniles. The percent similarity of food index was great between sexes and lower in different age group. The IFD and the BTN in different ages was the greatest in adults and the lowest in juveniles. The general beneficial coefficient,the beneficial coefficient in different gender and ages were V_(Total) = 22. 44%, V_(Female) = 12. 76%,V_(Male) = 9. 83%. The P. frontalis is a species beneficial to the desert steppe
