摘　　要：通过对采自贵定岩下大鲵自然保护区279份苔藓植物标本整理鉴定表明,该区共有苔藓植物35科,74属,131种(包括亚种、变种)。其中苔类植物9科,10属,18种;藓类植物26科,64属,113种。优势科为凤尾藓科Fissidentaceae、丛藓科Pottiaceae、真藓科Bryaceae、提灯藓科Mniaceae、羽藓科Thuidiaceae、青藓科Brachythe-ciaceae、灰藓科Hypnaceae、细鳞苔科Lejeuneaceae;优势属为凤尾藓属Fissidens、扭口藓属Barbula、丝瓜藓属Pohlia、匍灯藓属Plagiomnium、羽藓属Thuidium、青藓属Brahchythecium、细鳞苔属Lejeunea。对该区优势科分析可知,其苔藓植物以温带性质为主。After having identified the 279 bryophytes specimens collected from Yanxia Andrias davidianus Nature Reserve. In total 35 families ,74 genera, 131 species （including subspecies and variation） ,for liveworts ,there are 18 species,belonging to 10 genera of 9 families,while for mosses,26 families,64 genera and 113 species were identified. Fissidentaceae, Pottiaceae, Bryaceae, Mniaceae, Thuidiaceae, Brachytheciaceae, Hypnaceae, Lejeuneaceae are the 8 predominant families of Yanxia Andrias davidianus Nature Reserve, and the 7 predominant genera are follows： Fissidens, Barbula, Pohlia, Plagiomnium, Thuidium, Brahchythecium, Lejeunea. Through the analysis of the predominant families in this area. It can be concluded that the temperate elements are the main body of the bryophytes of the Yanxia Andrias davidianus Nature Reserve.
