摘　　要：牦牛生活于青藏高原海拔3000~5500m地区,具有高海拔低氧良好适应性。牦牛的高海拔低氧适应特性一直是研究热点,对牦牛育种及高原医学均具有重要意义。已有的研究从气管、肺、心脏等呼吸器官组织结构、血液氧运生理、细胞代谢、分子水平等方面分析其结构功能特征与适应性机制。本文就牦牛低氧适应的研究进展进行综述,供进一步研究参考。The yak （Bos grunniens） lived in 3000~5500 m region of Tibetan plateau, and was charac- teristic in adaption to high altitude hypoxia. High--altitude hypoxia adaptation of Yak had always been a hot research topic, which was meaningful to yak selective breeding and plateau medicine. Function--struc- ture feature and adaptability mechanisms were well studied by analyzing the configuration and function of respiratory organs （trachea, lung, and heart）, the physiological process of blood oxygen transport, cell metabolism, and some function genes in yaks versus cattle. We summarized these published investigations as reference for further study.
