摘要
采用实地调查及生态地理比较法等方法研究表明,藏山羊主产区约分布在北纬26°~36°(东经75°~104°)之间的生态地理区,以我国青藏高原为分布中心,藏山羊有两个生态类型,即高原型和山谷型,二者其分布地区的自然生态环境、羊的体格、毛被特征、解剖特征、血液生理指标及生化遗传标记等方面均有差异。
The study shows that there are more than 725.3 milion Tibetan goats in the mainproduct area,distributed between the area of 26°~36° north latitude and 75°~104° east latitude.There are two ecotypes of Tibetan goats (Plateau type and mountain-vally type).They are differentfrom each other in natural ecological environment,body size,hair tuft,physiological target andbiochemical genetical marker in blood,which can be exploited and used according to ecotypes.
