| 摘 要： | 摘要：以浙江丽水地区132株初选浙江红山茶单株为材料，采用主成分分析法对其10个观赏性状进行分析，同时对浙江红山茶的观赏性状进行评价。结果表明：主成分分析可将该10个性状综合为5个主成分，其累计贡献率为84.923%。以5个主成分的贡献率为权重结合各观赏性状相关矩阵的特征向量，建立观赏性状评价模型，评选出最优的35个单株，与浙江红山茶单株实际表现相符。

| Abstract: | Ten ornamental characters of 132 Camellia Chekiangoleosas， which were preliminarily selected from Lishui， Zhejiang province， were analyzed by principle component analysis for comprehensive ornamental evaluation of the trees. The results showed that 84.923% information of ten ornamental characters could be condensed into five principle components. The model of ornamental evaluation was established by the contribution proportion of five principal components as the weight coefficient and eigenvectors of correlation matrix of ornamental traits in Camellia chekiangoleosa. Thirty\|five superior trees were finally screened out， with the results similar to the actual performance of practical phenotype． |
