摘 要：
采用食团分析法对阿尔金山自然保护区大鵟的夏季食性进行分析。2012年7月至8月累计收集198份大鵟食团样品。分析结果表明,大鵟的食物组成中以啮齿类为主,鸟类为辅,以数量频率计,啮齿类占92.61%,啮齿类中高原鼠兔最多,占总数的82.27%,鸟类占7.39%。以生物量计,高原鼠兔和高原兔构成了大鵟夏季食物的主体,分别占到食物总量的80.61%和16.09%。无论从个体数量还是生物量,高原鼠兔都是大鵟最重要的食物类型。食性分析结果表明,大鵟对控制高原鼠兔的危害发挥积极作用。

摘 要：
The pellet analysis method were applied to investigate summer feeding habits of Buteo hemilasius in Altun Mountain National Nature Preserve,Xinjiang.198 pellet samples of Buteo hemilasius were collected from July to August,2012.The analysis result showed that the diet of Buteo hemilasius mainly were composed of rodents,while bird species were assistance.By quantitative calculation,rodent species accounted for 92.61%.The plateau pika accounted for maximum in rodent species,accounting for 82.27%in the total,bird species accounted for 7.39%.According to the biomass to be calculated,the platea pika and plateau rabits were mainly constituted of summer diet of Buteo hemilasius,which accounted for 80.61% and16.09% of total food compsition.No matter what number of induviduals or biomass,the palteau pika was the most important food type of Buteo hemilasius.The feeding habits analysis result showed that Buteo hemilasius played an active role in the controlling plateau pika.
