摘　　要：DNA barcode是一段特殊的、可用于物种鉴定的DNA序列。目前在动物中最常用的DNA barcode是细胞色素C氧化酶1号基因(COI)的部分序列。随着标准数据库的建立,基于COI基因的DNA barcode在动物分类学和生态学中得到了广泛应用。但是,采用COI基因作为DNA barcode所隐含的涉及线粒体的进化历史、遗传特性和物种成种时间的默认前提,并非完全成立,由此引发了许多问题。本文阐述了基于COI基因的DNA barcode对分类学和生态学的影响,目前存在的问题,以及可能的研究方向。DNA bareode is a special DNA sequence which can be used as a tool for species identification. At present, the most commonly used DNA bareode in zoological study is a sequence coming from eytoehrome e oxidase subunit 1 （COI）. With the establishment of standard data ba- ses, the COI-based DNA bareode has gained its wide application in animal taxonomy and ecology, and profoundly affected these research fields. However, the silent assumptions for DNA barcode that related to the evolution history and inheritance of mitoehondria and speeiation haven＇ t been completely confirmed, and thus, some problems are created. This paper discussed the effects of COI-based DNA bareode on animal taxonomy and ecology, the existing problems in its studies, and the future prospect of its applications.
