摘要: 2000 年7 月中旬至8 月上旬, 大批蒙古野驴从蒙古共和国进入我国内蒙古自治区巴彦淖尔盟乌拉特中旗和乌拉特后旗境内。2000 年9 月对该地区蒙古野驴的数量、分布和保护情况等进行了考察, 发现蒙古野驴主要活动在巴彦淖尔盟乌拉特中旗和乌拉特后旗中蒙边境沿线的梭形狭长地带。蒙古野驴活动区东端最南点在乌拉特中旗敦德乌素嘎查(42°17′N , 108°30′E) , 距边境23 km , 西端最南点在乌拉特后旗乌力吉图嘎查以西(42°08′N , 106°36′E) , 距边境12 km。活动区中部的南限在北纬42°01′, 距正北方边境44 km , 活动区面积约5 380 km2 。根据样带法调查计算估计该分布区蒙古野驴总数约在11 400 头左右。目前蒙古野驴种群在该地区的分布尚未完全稳定。密集的人口, 有限的食物资源和偷猎是影响蒙古野驴种群在该分布区稳定生存的主要因素。

Abstract: From mid-July to early August 2000 , a large herds of Mongolian wild ass emigrated from Republic of Mongolia into Wulate Zhongqi and Wulate Houqi of Bayannaor League in Inner Mongolia Autonomous Region , China. We investigated the distribution range , population size and current conservation status of Mongolian wild ass in September 2000. The southern border of the distribution region of the wild ass ranged from Dundewusu village of Wulate Zhongqi (42°17′N , 108°30′E) to the west of Wulijitu village of Wulate Houqi (42°08′N , 106°36′E) . The national boundary between China and Mongolia is the northern border of the current range of the wild ass. The current distribution area of the wild ass is 5 380 km2 , and the estimated total numbers of Mongolian wild ass is 11 400 according to the belt transects method. The current distribution of Mongolian wild ass in the region is still not quite stable. High density of wild ass , frequent human activities , limited pastures , and poaching are the main factors to threat their survival in the region.
