摘要
蒙古野驴(Asinus h.hemionus)分布于内蒙和甘肃西北角、新疆东北部至准噶尔盆地西部。1982年航调,卡拉麦里山保护区内有358头,0.02头/平方公里;1986年调查为0.03头/平方公里。估计目前我国境内不超过2000头。西藏野驴(Asinus k.kiang)分布于西藏西部、新疆南缘山地;A.k.holdereri分布于除湟水河谷外青海全境、四川西北角、甘肃祁连山。1984年调查,阿尔金山保护区内有41,262头,0.917头/平方公里。估计我国境内种群约在20万头以上。多年考察未发现野马(Equus przewalskii),目前可能在北塔山以东尚有少数残存。
Asinus h.hemionus: It is distributed at northwestern corner of Inner Mongolia and Gansu as well as in an area stretching from northeast of Xinjiang to west of Zhungaer Basin, covering about 140,000 Km2 (N.40°20'-46°40', E.85°40'-107°30'). According to the aerial survey in 1982, there were 358 wild asses in the Nature Reserve of Kala-meili Mt. with the density of 0.02 ass/Km2. The survey in 1986 showed that the density reached 0.03 ass /Km2. In the last few ten years, its distribution region has been reducing continuously with population going down rapidly. Now, we estimate that the population is not more than 2.000 in China.
Asinus kiang: A.k.kiang is distributed in west of Tibat and the Mts. on the so-uthern verge of Xinjiand; A,k,holdereri in Qinghai except the vally of Huangshui river, northwestern corner Sichuan and east of Qilianshan Mt. in Gansu, covering abc-ut 1,500,000 Km2. (N. 28°30'-39°20', E. 75°15'-103°00'). According to the survey ver 1984, there were 41,262 wild asses in the Nature Reserve of Aerjin Mts. with the density of 0.917 ass/Km2 The range is still very wide and the population is larger about over 200,000 estimated.
Equus przewalskii: We have not seen Wild horse, though we hav e surveyed it for years. Only a few wild horses survive possibly in the east of Beitashan Mt., covering about 10,000 Km2 (N.41°44'-45°13', E.91°46'-93°50)
