摘要: 在江西阳际峰自然保护区调查的25个样地中,共采集到地面生苔藓植物34科56属106种(包括1变种).应用CCA排序法,首次定量分析了该区38种主要地面生苔藓植物与环境因子的关系.结果表明,苔藓植物的分布和生物多样性受环境因子的影响较大,湿度、基质是影响地面生苔藓植物分布的主要环境因子,其他影响因子依次为乔木郁闭度、灌木盖度、海拔高度、人为干扰和坡度.

Abstract: A total of 106 species (including one variety) belonging to 56 genera and 34 families of terrestrial bryophytes were collected from 25 sampling quadrates in YangjifengNature Reserve,Jiangxi Province,China.Canonical Correspondence Analysis (CCA) determined the relationship between terrestrial bryophytes (38 species) and their environmental variables for the first time in this area.Results indicated that environmental factors influenced the distribution and biological diversity of bryophytes considerably.The main environmental variables were humidity and substructure,and the secondary variables included canopy density,shrub coverage,altitude,gradient,and human activities.
