| 摘 要： | 用主成分分析和聚类分析法对１０个中国牦牛类群的５个体型性状和９个产地生态因子的资料进行处理、分析，以确定牦牛体型大小与生态因子的关系。结果表明：牦牛体型大小与其所所生态环境因子有着紧密的联系；１０个牦牛类群按体型大小和产地的生态因子可分为２类，这与以往的分类和牦牛类形成的历史基本一致。

| Abstract: | Information about 5 body shape traits and 9 ecologocal factors of habitation for 10 groups of Chinese yaks have been processed and analyzed by the method of principal component analysis and clustering analysis to determine the relation between yak body size and ecological factors. Result indicates: Yak body size has close relation with its ecological environmental factors; 10 yak groups can be divided into 2 types according to body sizes and ecological factors of habitation, which basically conforms with previous grouping as well as the history of yak group formation. |

| Keywords: | Chinese yak principal component analysis cluster analysis ecological factor |
