摘要:

利用支持向量机分析了气象条件对龙井43茶树春季生产的茶叶中茶多酚、氨基酸、咖啡因、总儿茶素含量的影响。结果表明:支持向量机能很好地分析气象因子与茶叶生化成分的关系;茶叶生化成分和气象因子的相关性大小与茶叶生化成分和该气象因子的敏感性排序不存在一一对应关系;气象因子对龙井43春茶生化成分的影响可划分为敏感区间和不敏感区间,在敏感区间,生化成分随气象因子显著变化;在不敏感区间,生化成分不随气象因子变化。

Abstract: By using the support vector machine technology, the impacts of meteorological conditions on the biochemical component contents (e.g., tea polyphenol, amino acid, caffeine and total catechins) of the spring tea Longjing 43 were analyzed. The results showed that the support vector machine was useful and efficient for analyzing the relationships between meteorological factors and the tea biochemical components. The order of correlation coefficients for the tea biochemical components with the meteorological factors was not exactly in accordance with the order of the meteorological factors based on their sensitivities to the selected meteorological factors. The impacts of meteorological factors on the tea biochemical components could be classified into sensitive and insensitive sections. The biochemical components significantly changed in the sensitive section, but did not vary in the insensitive section.
