| 摘 要： | 在整理鉴定中国帕米尔高原禾本科植物标本的基础上,对该区禾本科植物区系特点进行了研究。结果表明:该区禾本科植物资源丰富,有32属132种,分别占新疆禾本科属、种数的45.1%和35.1%;寡种属、单种属相对较多。该区植物区系地理成分多样,汇集了6个分布类型和2个变型,其中温带性质明显的有25属,占总属数的80.6%,热带成分占一定比例,为18.8%,在属级水平上有东亚、中亚和地中海区系成分的渗入。与邻区植物相比,喀喇昆仑—昆仑山与中国帕米尔相似系数最高。

| Abstract: | By means of collecting,and investigating Gramineae in Pamirs Plateau of China,we studied floristic characteristics of Gramineae in this area.The results indicate that resource of Gramineae is abundant,which contains 32 genera,132 species,account for 45.1% of genera and 35.1% of species in Xinjiang;the monospecific genus and olig-specific genus are relateively more.The flora elements are various.The Pamirs consists of 6 distribution-types and 2 variety types.and its temperate quality is obvious,25 genera,takes for 80.6% of total in Pamirs Plateau of China,but the tropics takes a proportion about 16.2%.And on the level of genera,there are East Asia,Central Asia and Mediterranean flora elements intrusion.Compared with neighborhood,the similarity coefficient of Karakorum and Kunlun mountains to Pamirs Plateau of China is the tallest. |
