摘要
利用主成分分析和聚类分析对我国8个地方鸭品种(巢湖鸭、高邮鸭、山麻鸭、广西小麻鸭、金定鸭、荆江麻鸭、攸县麻鸭、临武鸭)的体尺、体质量及其中心产区生态特征的资料进行了多元统计分析。结果表明,主成分分析选取前3个特征值作为3个主成分(占总信息量的90.854%),并根据各品种的前3个主成分值计算相似系数,并藉以进行聚类分析,8个地方鸭品种可划分为2类,这说明生态因子亦是品种分类中的一个重要方面。
The multivariate statistics analysis of three aspects（i, e. body size, body weight and eco- logical characters）were carried out on 8 Chinese native duck breeds by the methods of principal component analysis and cluster analysis. The results showed that fore 3 character values were se- lected as the principal component（occupied 90. 854o/oo of total information amount） ,and the 8 Chi- nese native duck breeds were divided into two types according to 3 principal component values of each breeds, which suggested that the ecological factor was also an important side on the breed re- gion classification.
