摘　　要：本文对纳雍珙桐自然保护区的722份藓类植物标本进行整理和鉴定。结果表明:该地区有藓类植物33科81属228种(包括亚种、变种)。优势科有曲尾藓科Dicranaceae、丛藓科Pottiaceae、羽藓科Thuidiaceae和灰藓科Hypnaceae等;优势属有凤尾藓属Fissidens、青藓属Brachythecium和绢藓属Entodon等。通过对本区优势科属的区系成分进行分析,得出该地区温带分布性质较明显,并有向热带、亚热带分布的趋势。Total of 722 moss specimens from Gongtong Nature Reserve of Nayong were identified in the present work. The results showed that there were 228 species, 81 genus, 33 families （including subspecies and vari- ation species） of mosses in the region. The dominant families were Dicranaceae, Pottiaceae, Thuidiaceae and Hypnaceae, and the dominant genera were Fissidens, Brachythecium and Entodon etc. Based on the fioristic composition of predominant families and genera in this area, the distribution of the temperate elements was obviously observed, and a trend for tropical and subtropical distribution was also investigated.
