摘　　要：基于线粒体DNA(mtDNA)中CoI基因的部分序列(1300 bp)对雀形目雀科(Fringillidae)36种鸟类进行系统发育分析。对数据集构建NJ树、Bayes树和ML树。对建树结果进行分析,发现铁爪鹀(Calcarius lapponicus)与鹀属(Emberiza)鸟类的亲缘关系比其他雀科的鸟类更近;支持蓝鹀(Latoucheornis siemsseni)隶属于鹀属的观点;证实了黄颈拟蜡嘴雀(Mycerobas affinis)与黑尾蜡嘴雀(Eophona migratorius)之间紧密的亲缘关系;发现长尾雀(Uragus sibiricus)和朱鹀(Urocynchramus pylzowi)之间亲缘关系很远,而与朱雀属(Carpodacus)有较近的亲缘关系;结果支持雀类与鹀类的亚科级分类水平。Phylogenetic relationships of 36 Fringillidae species based on mitochondrial Col gene sequences were reconstructed using the Bayesian （BI） maximum-likelihood （ML） and Neighbor-joining（NJ）methods. The results suggest that the relationship of Calcarius lapponicus and Emberiza is more closely related than other Fringillidae species.Our results support the view that Latoucheornis siemsseni is included in Genus Emberiza as E. siemsseni, and confirms that there is a close relationship between Mycerobas affinis and Eophona migratorius. This study also finds that Urocynchramus pylzowi is distantly related to Uragus sibiricus, but Uragus sibiricus and Carpodacus are closely related. The result also supports that fringillids and emberizids can be listed into two subfamilies under the family Fringillidae： Fringillinae and Emberizinae.
