摘　　要：The 18 species of bird studied originally are known to belong to muscicapids, robins and sylviids of passerines, but some dis- putations are always present in their classification systems. In this experiment, phylogenetic relationships of 18 species of passerines were studied using Adenylate Kinase lntron 5 （AKS） sequences and DNA techniques. Through sequences analysis in comparison with each other, phylogenetic tree figures of 18 species of passerines were constructed using Neighbor-Joining （N J） and Maximum-Parsimony （MP） meth- ods . The results showed that sylviids should be listed as an independent family, while robins and flycatchers should be listed into Musci- capidae. Since the phylogenetic relationships between long-tailed tits and old world warblers are closer than that between long-tailed tits and parids, the long-tailed tits should be independent of paridae and be categorized into aegithalidae. Muscicapidae and Paridae are known to be two monophylitic families, but Sylviidae is not a monophyletic group. AK5 sequences had better efficacy in resolving close relationships of interspecies among intrageneric groups.本研究的18种鸟分别属于雀形目中的鸫类、鸲类和莺类,这几类鸟的分类问题一直存在争议。实验采用核蛋白激酶基因内含子5(AK5)和DNA测序法来分析这18种鸟的分子系统发育关系。并通过序列分析比对,运用邻接法和最大简约法构建了雀形目18种鸟类的系统发育树。结果表明:莺类独立成科;歌鸲和姬鹟被归入鹟科下;长尾山雀与莺科的亲缘关系比与山雀类的亲缘关系近,长尾山雀应从山雀科中分离出来,建议单列成长尾山雀科。从类群的单系性来看,鹟科和山雀科分别构成单系,而莺科不是一个单系群。通过构建的系统树来看,AK5序列在解决同属内近缘物种间的亲缘关系方面起到一定的作用。
