摘要/Abstract

摘要： 调查和分析了贵州贞丰县喀斯特石漠地区的3座典型峰丛、3个山段上苔藓植物群落的种类组成及其生态特征。研究区域内，苔藓植物群落的种类组成有12科16属19种。苔藓植物群落共21个类型，其中纯群落占83.3%，两种及两种以上苔藓组成的群落占26.7%，占优势的群落是皱叶牛舌藓群落（Anomodetum）、卷叶湿地藓群落（Hyophiletum）和卷叶毛口藓群落（Trichostometum）。苔藓植物群落物种为适应旱生、干燥和强光直射的环境，生活型仅有交织型和矮丛集型两类。由于人类强烈的活动破坏了原有的生态系统，苔藓群落的分布在石漠峰丛中显示出了特异性，苔藓群落的丰富度为山顶＞山腰＞山脚。各山段的皱叶牛舌藓群落均有最大的生态优势度，具有治理石漠的潜在价值。

Abstract: The composition and ecological characteristics of bryophyte communities were investigated from three peak clusters of karst rock desertification in Zhenfeng county, Guizhou province. There are 21 types of bryophyte communities in the area, in which pure communities take up 83.3% and those with more than two species take up 26.7%. The predominant communities are Anomodetum, Hyophiletum and Trichostometum. There are only two lifeforms which are Wefts and Short turfs occurred on the area owing to the dry and strong light environment. In karst rock desertification peak cluster, bryophyte communities are rich in peak and scarce in bottom. The results indicate that the Anomodetum has the potential value to control rock desertification contributing to its highest ecological dominance presenting all sites.

Key words: bryophyte communities, karst rocky desertification, peak cluster, ecological characteristics
