作者于 2 0 0 1年 5月中旬在卡拉麦里山自然保护区对野驴进行了为期一周的调查 ,估算了该保护区内蒙古野驴的资源储量。分布密度为 0 .6 1± 0 .14头 /km2 ,保护区内约有野驴 2 6 32 - 42 0 0头 ,数量有较大增长 ,并对蒙古野驴迁移和集群活动规律作了观察。

Equus hemionus inhabit mainly in the deserts, semi-deserts and desert grasslands in Central Asia, is a protected species of wild animals in grade A in China. In China, Equus hemionus inhabit mainly in the western part of Inner Mongolia, northwestern part of Gansu Province, and in the areas of Yiwu, Barkol and Mori as well as the Junggar Basin in north Xinjiang. The authors carried out an investigation lasting a week about the Equus hemionus inhabiting in the Karamori Mountain Nature Reserve in mid-May 2001. The Equus hemionus resources in the nature reserve are estimated. The results show that the inhabiting density of Equus hemionus is 0.61±0.14 per square kilometer, the total number of Equus hemionus is 2632～4200 and has increased obviously. The migration routes and the droves of Equus hemionus are also observed.
