摘要
简述茶叶中稀土元素的组成、来源和特征,其中重点介绍利用稀土元素组成和含量差异,以及结合主成分分析、聚类分析和判别模型等手段对茶叶原产地进行判别的研究现状,指出当前对茶叶原产地判别的研究尚有欠缺,并对未来该领域研究的方向进行展望,旨在为将来稀土元素在茶叶原产地溯源中的广泛应用提供理论基础和参考价值.
The brief overview of the types,sources,and characteristics of rare earth elements in tea were introduced.The research current situation of tea origin distinguishing based on differences in the content of rare earth elements was reviewed combined with principal components analysis,cluster analysis and discrimination model.Then some problems and developing aspects on the research of tea origin discrimination were discussed,which aimed to provide the theoretical basis and reference for relevant studies and wide application of rare earth elements in tea origin discrimination in the near future.
