| 摘 要： | 中国帕米尔高原约有种子植物963种(包括变种), 隶属59科303属。其中裸子植物3科、3属、12种, 被子植物56科、300属、951种。在区系科属分级水平上, 寡种科、单种科占绝对优势, 超过50种的大科仅有4科, 分别占总属数、总种数的40.26%和46.21%, 区系优势现象十分明显; 单种或少种属也较多, 属种比值偏高, 表明区系组成上的复杂性。在区系地理成分中则是以温带成分为主的北温带成分占主导地位, 其次是旧世界温带分布成分和地中海、西亚至中亚成分, 而热带成分十分微弱。

| Abstract: | Approximately 963 seed plant species, classified into 59 families and 303 genera, are in the Pamirs region of China. Gymnosperm have 3 families,3 genera and 12 species and dominant Angiosperm have 56 families,300 genera and 951 species. One-species and Minor-species of family are predominantly. There are 4 families with more than 50 species .The ratios of gerera and species to pamirs region are about 40.26% and 46.21% in 4 families, so phenomenon of the flora is obviously. Single-species or species-poor genera are more, so composition of the flora is complex. Based on the analysis of genera , the temperate composition, mainly including north temperate, is dominant; Old World Temperate, Mediterranean, Western Asia and Middle Asia Composition are very important; tropical composition occopies only a small percentage. |
