摘　　要：木灵藓科(Orthotrichaceae)是藓类植物中的第3大科。该科不仅种类多,生态类型特殊,而且是世界公认的多样化程度高、分类难度大、系统关系复杂的类群。当代木灵藓科植物分类系统学研究主要集中在该科的地区志编写和专属分类修订。目前,除了热带美洲、热带非洲的变齿藓属(Zygodon)和火藓属(Schlotheimia)部分类群外,木灵藓科主要类群的分类修订工作已基本完成,但是有关亚科和属的划分和地位以及各属之间的关系等方面仍存在众多争议。木灵藓科分支系统学研究也不够系统全面,有的仅应用了单个基因片段,或者只涉及少数类群。因此,需要基于更多的分子和形态学性状,进一步开展世界木灵藓科植物的系统发育研究,建立一个更趋自然的木灵藓科分类系统。Orthotrichaceae is the third largest moss family according to species number. The family is rich in species and especially ecotypes but is also a taxon with high diversity, many taxonomic problems, and complex systematic relationship within its groups. The contemporary taxonomy and systematics of Orthotrichaceae has mainly focused on its local flora and monographs of relevant genera. The major genera have been taxonomically revised, except for some species names of Zygodon and Schlotheimia in tropical America and Africa. However, there are many disputes about subfamily divisions, systematic level of some genera, and relationships among different groups within the family. Moreover, previous relevant cladistics studies of Orthotrichaceae included only single gene fragments or did not include all taxa within the family. Therefore, more molecular and morphological data are needed for further phylogenetic research of the Orthotrichaceae family.
