摘　　要：为了更好的说明子午岭自然保护区与其它地区藓类植物区系之间的关系,真正揭示该保护区藓类植物区系的特征,通过选取国内其它8个邻近地区,与子午岭自然保护区藓类植物在物种丰富度、极点排序、聚类分析、区系地理成分等方面做出了进一步的比较和分析。结果显示,子午岭自然保护区与庞泉沟、七老图山和小五台山的藓类植物亲缘关系较近,神农架、佛坪、三工河、峨嵋山的藓类植物区系与子午岭自然保护区相差较远,大围山与该区亲缘关系最远。此结果与1963年陈邦杰教授关于苔藓植物的区系划分相一致。In order to better illustrate the relationship of mossflora among Ziwuling Nature Reserve and other areas,reveal the feature of mossflora of the Reserve,eight other adjacent regions are selected as the comparision with Ziwuling Nature Reserve,made further comparison and analysis with Ziwuling Nature Reserve,such as species abundance,polar ordination,cluster analysis and moss geographic elements.The result revealed there was closer relationship among Pangquangou Nature Reserve Mt.Qilaotu,Mt.Xiaowutai and Ziwuling Nature Reserve,and distant relationship among Shennongjia Nature Reserve,Sangong River Valley,Mt.Emei and Ziwuling Nature Reserve.The relationship between Daweishan Nature Reserve and Ziwuling Nature Reserve was farthest.The result was consistent with the devision of Bryoflora by Professor Chen Bangjie in 1963.
