摘　　要：DNA条形码主要目的是物种鉴定和新物种或隐存种的发现,而DNA条形码参考数据库是物种快速鉴定的重要基础。目前中国维管植物DNA条形码参考数据库正在建设之中,借助于公共数据库(NCBI)和初步建立的中国植物DNA条形码参考数据库,运用DNA条形码数据开展了植物标本鉴定的核查工作:(1)比较DNA序列信息与标本鉴定信息,从科、属、种级水平查找鉴定错误的标本;(2)基于有较好研究基础的DNA条形码参考数据库,开展未知标本的鉴定;(3)通过对标本核查的总结,提出DNA条形码参考数据库建设过程中的几点建议。DNA barcoding comprises two distinct aims： specimen identification and species discovery. To achieve these goals, a DNA barcode reference library is indispensable and is currently under construction for Chinese plants. In this paper, we used the existing public database, NCBI, and also our DNA barcode reference library, which is under construction, to identify plant specimens. By combining DNA barcode sequences with scientific names deter- mined by taxonomists, we first attempted to find incorrectly identified specimens and also to check specimens whose DNA sequences were wrongly labeled. Secondly, we attempted the identification of unknown specimens in some groups for which DNA bareodes are available. Thirdly, we make some suggestions for the development of a plant DNA barcode reference library.
