摘要:

中国的蒙古野驴(Equus hemionus)和西藏野驴(E. kiang),其分布区在动物地理区划上同属古北界,但蒙古野驴分布在蒙新区,西藏野驴在青藏区,两区的自然地理特点差异显著。蒙古野驴分布区面积约为 14×104 km2(40°20´~46°40´N、85°40´~107°30´E),海拔高程介于 700~1500 m,初步估算数量不超过2000头;西藏野驴分布区面积约为97×104 km2(27°48´~39°27´N、78°40´~103°00´E),海拔高程介于 3000~5500 m,初步估算有近 90 000头。地质时代野驴分布较广泛,历史时期分布区不断变迁和退缩,本文对其原因亦作了初步探讨。

Abstract: During 1993~1997 , the status of Chinese wild ass was assessed. The Chinese wild ass is divided into two species , i. e. Mongolian wild ass or chigetai , kulan ( Equus hemionus) and Tibetan wild ass or kiang ( Equus kiang) . Equus hemionus is distributed in the Meng-Xin Region , while Equus kiang was found in the Qin- Zang Region , including Inner Mongolia , Xinjiang , Tibet , Qinghai , Gansu and Sichuan Province. The distribution area of Mongolian wild ass is about 0. 14 million km2 (40°20′~46°40′N ,85°40′~107°30′E) , about 700~1500 m in altitude , with a population size less than 2000. Tibetan wild ass is distributed in an area of about 0. 972 507 million km2 (27°48′~39°27′N ,78°40′~103°00′E) ,about 3000~5500 m in altitude , with an estimated population size of 88 871.
