| 摘要: |
| 为全面掌握云南省苔藓植物区系状况，本文对香格里拉市苔藓植物进行了调查。采集苔藓植物标本1316份，经鉴定，共有38科88属194种，其中苔类植物11科12属15种；藓类植物27科76属179种。将种数位于前5位的科、属定义为优势科、属，则优势科为丛藓科（Pottiaceae）、提灯藓科（Mniaceae）、真藓科（Bryaceae）、羽藓科（Thuidiaceae）及金发藓科（Polytrichaceae），共包括31属93种，分别占该地区苔藓植物总属数和总种数35.23%和47.94%；优势属有真藓属（Bryum）、青藓属（Brachythecium）、匐灯藓属（Plagiomnium）、对齿藓属（Didymodon）和曲尾藓属（Dicranum），占该地区苔藓植物总种数的23.71%。香格里拉市苔藓植物区系划分为10种区系分布类型，以北温带成分为主（36.72%）,东亚成分次之（19.21%），并具有较高的中国特有性（10.73%）。通过Sorenson相似性系数比较香格里拉与云南鸣凤山、木洪大山、多依河、纳板河四个地区的物种相似性，结果表明，香格里拉与各地区的物种相似度存在较大差异。香格里拉特殊的地理位置和气候条件造就了其独特的苔藓植物多样性。 |

| Abstract: |
| To comprehensively understand the bryophyte flora of Yunnan Province, this study investigated the bryophytes of Shangri-La City. A total of 1,316 bryophyte specimens were collected and identified, comprising 38 families, 88 genera, and 194 species. Among them, there were 15 species of liverworts from 11 families and 12 genera, and 179 species of mosses from 27 families and 76 genera. The dominant families, defined as those with the highest number of species, were Pottiaceae, Mniaceae, Bryaceae, Thuidiaceae, and Polytrichaceae, encompassing 31 genera and 93 species, accounting for 35.23% of the total genera and 47.94% of the total species in the region. The dominant genera were Bryum, Brachythecium, Plagiomnium, Didymodon, and Dicranum, representing 23.71% of the total species in the region. The bryophyte flora of Shangri-La City is classified into 10 distribution types, with a predominance of North Temperate elements (36.72%), followed by East Asian elements (19.21%), and a high degree of Chinese endemism (10.73%). A comparison of species similarity using the Sorenson similarity coefficient between Shangri-La and four other regions in Yunnan (Mingfeng Mountain, Muhong Mountain, Duoyi River, and Naban River) revealed significant differences in species similarity. The unique geographical location and climatic conditions of Shangri-La contribute to its distinctive bryophyte diversity. |
