摘要
本文以小尾寒羊为例，应用聚类分析的方法对三十一个生态区域的八个气候因子进行了分类研究，介绍了聚类分析在家畜引种中的应用。结果表明，这三十一个生态区域可以分为六类，凡与小尾寒羊原产地分为同一类的生态区域可以引种小尾寒羊，其他类的生态区域不宜引种小尾寒羊。
xample of
Xiao Wei Han Sheep,dealt with theapplication of cluster analysis method to the studies on 8
climatefactors of 31 ecologicalregions and classified the materials used,and introduced the
application of cluster-analysis in introducing animal strain.The results of cluster analysis showed
that these e-cological regions can be classified six kinds of clasfication,the ecological regions
whichhave the same classification with the original regions of Xiao Wei Han Sheep can intro-duce
Xiao Wei Han Sheep,while other ecological regions had better not introduce Xiao Wei Han Sheep.
