新疆盘羊(Ovis ammon)的地理分布特征

新疆盘羊(Ovis ammon)分布可划分为三个阶段:10 000～5000年前为石器时代分布，5000～50年前为历史分布，50年前至今为现代分布。新疆盘羊分布非常广泛，从南边的昆仑—阿尔金山至最北的阿尔泰山，从东天山到准噶尔界山，甚至罗布泊和帕米尔都有分布。在昆仑—阿尔金山、中天山、巴尔鲁克山和玛依勒山，盘羊为连续分布；其它地区为成片分布、零星分布和季节性分布。盘羊栖息的海拔高度可从920～4600 m，垂直分布由于高程－纬度效应，从南到北一般随着纬度升高而降低。在水源缺乏的地区，其垂直分布还受地表水和泉水分布的制约。

Geographical distribution of argali (Ovis ammon ) in Xinjiang

Based on rock carving,historical records and field investigation,the distribution of argali (Ovisammon) can be divided into three stages, i. e. Stone Age (10000~5000 years ago), 5000~50 years ago,and current distribution. At present, argali is widespread in Xinjiang, even in Lop the and Pamirs.The continuous distributions are in the middle Tianshan Mountains, south Altun and Kunlun Mountains, as well as thewes part of Junggar, while the others are fragmentary or seasonal distributions. Argali are distributed at theelevation of 920~4600 meters. As the latitude increases,it's vertical distribution becomes low. In arid areas,the distribution of argali depends on springs and surfare water, not correlaed with latitude.
