摘要: 对浙江西天目山不同海拔苔藓植物进行调查,从种类组成、相似性、α多样性和β多样性等方面进行了苔藓植物物种多样性分析.结果表明,海拔1 100 m处落叶阔叶林下的苔藓植物种类最多,物种丰富度最高;它与海拔1 300 m落叶矮林下苔藓植物的相似性系数也最高;而海拔800~1 100 m之间的β多样性最大,这一区段苔藓植物的物种变化速率最快,种类更替最明显.西天目山海拔1 100 m处苔藓植物物种多样性最高,是该山体苔藓植物多样性保护的关键区段.

Abstract: In this paper,an investigation was made on the bryophytes at different altitudes of West Tianmu Mountain,with their species composition,similarity,and α- and β-diversities.The results showed that at altitude 1 100 m,the bryophytes under deciduous broad-leaved forest had the highest species number and richness,and the highest similarity with the bryophytes under deciduous broad-leaved shrub at 1 300 m.The β diversity index at altitude 800~1 100 m was the largest,suggesting an obvious change and alternation of bryophyte species there.At altitude 1 100 m,the species diversity of bryophytes was the highest,where should be the key area for bryophyte diversity conservation in West Tianmu Mountain.
