摘要
通过对九连山保护区苔藓植物现有资料的统计分析和补充调查。结果表明:(1)九连山自然保护区共有苔藓植物66科137属289种(含种下等级);(2)九连山苔藓植物物种组成丰富,其丰富度指数在江西省的5个保护区中排第2;(3)九连山苔藓植物区系成分复杂多样,共有13种类型,以东亚成分(占36.01%)和热带性质成分(占34.87%)为主,其区系成分表现为由南亚热带向中亚热带的过渡类型;(4)聚类分析显示九连山苔藓区系成分和江西马头山、广西九万山苔藓区系成分的相似性最高。
The study was based on the statistical analysis and recent supplementary investigation of bryophytes in Jiu-lianshan Nature Reserve.There were 289 species(including subspecies)belonging to 137 genera and 66 families of bryophytes in Jiulianshan Nature Reserve;The species composition of bryophytes in Jiulianshan was rich,and the rich-ness index of bryophytes in Jiulianshan was the second among the five protected areas in Jiangxi Province The bryo-phyte flora of Jiulianshan was complex and diverse,the main floristic elements were East Asia(36.01%)and tropical(34.87%).The floristic elements were transitional from south subtropical to central subtropical.Cluster analysis showed that the composition of bryophyte flora in Jiulianshan was most similar to that of Matoushan of Jiangxi and Jiuwanshan of Guangxi.
