| 摘 要： | 对882份标本进行鉴定,共记录沈阳市苔藓植物30科67属143种及变种,其中辽宁省新纪录种36种,东北新纪录种18种.区系分析表明本区苔藓植物以北温带成分为主（51.16%）,其次为东亚成分（16.28%）和中国特有成分（12.40%）,具强烈的温带性质,与该区地理位置和气候条件等相吻合,与种子植物的区系分布特点也一致.同其他城市地区苔藓植物属和种的相似性系数分析表明,沈阳市与同处辽宁省的抚顺市和鞍山市苔藓植物的亲缘性较大,而与其他城市地区亲缘性较小. |
| 关 键 词： | 沈阳 苔藓 新纪录 区系 相似性系数 |

| Abstract: | 143 species and varieties in 67 genera and 30 families of bryophytes are reported based on specimens from Shenyang City, Liaoning Province, China. Among them, 36 species are new to Liaoning Province and 18 to Northeast of China. Floristic analysis shows that North temperate elements take up the majority, approximating to 51. 16%, and followed by East Asian elements and Endemic to Chinese elements, accounting for 16.28% and 12.40~, respectively. The bryoflora obviously shows the temperate characters are similar to the flora of seed plants, locations and weather conditions. Coefficient of similarity at generic and specific level between Shenyang City and other cities or regions is calculated for the comparison of similarities between different floras. The result shows that the bryoflora of Shenyang City is close to those of Fushun and Anshan City, and far from bryofloras in other cities or regions. |
