摘　　要：对贵州香纸沟喀斯特区域苔藓植物多样性进行研究,发现该区苔藓植物种类丰富,区系地理成分复杂;不同生境的苔藓植物种类有明显差异;生态群落可分为水生群落、石生群落、土生群落、木生群落和叶附生群落等五大类;生活型可划分为矮丛集型、高丛集型、垫状型、平铺型、交织型、悬垂型、尾型、扇型和树状型等9种,其中,交织型、矮丛集型、高丛集型和平铺型占主导。并对香纸沟喀斯特区域苔藓植物多样性保护提出建议。Diversity of bryophytes in Xiangzhigou karst area was investigated in Guizhou province,P.R.China.It was very complicated in its floristic components.There was differenct bryophytes in the different habitats in Xiangzhigou karst area.The communities of bryophytes in Xiangzhigou karst area can be classified into 5 types.They are Hydrophytia,Petrophytia,Geophytia,Epixylophytia and Epiphyllitia.Based upon the opinion of Magdefrau,the life-forms of bryophytes in Xiangzhigou karst area can be classified into 9 types.They are Short turfs,Tall turfs,Cushions,Mats,Wefts,Pendants,Tails,Fans and Dendroids.Among of them,Wefts,Short turfs,Tall turfs and Mats are the dominant life-forms.There are some opinions to protect the bryophytes in Xiangzhigou karst area.
