摘　　要：【目的】全面调查和研究对新疆苔类植物资源,为新疆苔类植物系统分类学研究提供新资料。【方法】采用经典分类学方法进行物种鉴定。【结果】对新疆苔类植物2个新记录科—壶苞苔科Blasiaceae和拟复叉苔科Pseudolepicoleaceae,2个新记录属—壶苞苔属Blasia L.和睫毛苔属Blepharostoma Dumort.,5个新记录种—壶苞苔Blasia pusilla L.、粗裂地钱Marchantia paleacea Bertol.、睫毛苔Blepharostoma trichophyllum(L.)Dumort.、阔瓣裂叶苔Lophozia excisa(Dicks.)Dumort.和光萼苔Porella pinnata L.进行了首次报道,并对它们的识别特征、生境和地理分布进行了初步研究。【结论】通过对阿尔泰山和喀喇昆仑山山苔类植物资源调查研究鉴立,确立新疆阿尔泰山苔类现知有21科、25属和42种,在喀喇昆仑山有苔类7科、8属和11种,同时确定壶苞苔科和拟复叉苔科为新疆新记录科,壶苞苔属和睫毛苔属为新疆新记录属,壶苞苔、粗裂地钱、睫毛苔、阔瓣裂叶苔和光萼苔为新疆新记录种。【Objective】In this study,a systematic investigation on bepatic resou rces in Xinjiang,China was observed,as well they provide the new information f or studying the bryoflora of Xinjiang.【Method】By using classical taxonomic met hods combining with ultrastructural observation of bryophytes a series of liverw orts were identified.【Result and Conclusion】By studing and analise liverworts of Xinjiang Altay Mountains and Karakorum Mountains,were identified 42 species of Xinjiang Altay Mountains in 25 genera and 21 families,11 species of Karakorum Mountains in 8 genera and 7 families;Ascertaine that Blasiaceae and Pseudolepicoleaceae are newly recorded families,Blepharostoma Dumort.and Blasia L.are newly recorded genera,Blasia pusilla L.,Marchantia paleacea Bertol.Blepharostoma trichophyllum（L.） Dumort.,Lophozia excisa（Dicks.）Dumort.and Porella pinnata L.are newly recorded species in Xinjiang.
