疆岳驴是我国优良的乳肉兼用地方品种，为了加快对疆岳驴的选育、提纯复壮和保种速度，本研究选择101头疆岳驴进行体重和体尺测定，并应用R语言（2．15．0）进行相关和回归分析。结果表明，年龄对疆岳驴的体高、胸围和体重影响极显著（P〈0．001），对体长和管围影响显著（P〈0．05），其中1～3岁年龄组的体高、体长、胸围、管围和体重值最大，并且1～3岁公驴的体高、管围和体重显著优于母驴（P〈0．（35）。疆岳驴的体重与体尺性状有极显著的相关关系（P〈0．001），通过建立最优回归方程表明，影响体重的重要性状依次为胸围、体高和体长。建议疆岳驴在选育、提纯复壮和保种时应加大对胸围、体高和体长的选择力度，同时参照最优回归模型可以获得较好的效果。

Jiangyue donkey is an escellent local milk and meat breed in Xinjiang .To accelerate the speed of breeding, reproduction and conversation, correlation and multiple regression analysis between body weight and body size of 101 Jiangyue donkey was made by R Project (2.15.0). The results showed that age had a great significant effect on height at wither, heart girth and body weight (P〈0.001), and had a significant effect on body length and circumference of cannon bone, which the value of height at wither, body length, height at wither, circumference of cannon bone and body weight within 1-3 ages group were the highest compared other ages groups. And the height at wither, circumference of cannon bone and body weight of male more significantly better than female within 1-3 ages group .There were highly difference between body weight and body size (P〈0.001). The best regression model showed that the most important of effect on body weight was heart girth, height at wither and body length in sequence. To gain the better effect, heart girth, height at wither and body length should be more chosen and the
