【摘要】 中国帕米尔高原位于我国新疆西南部,是天山、昆仑山、喀喇昆仑山和兴都库什山等交汇而成的大山结,地处偏远,自然条件恶劣。菊科为该区种子植物第一大科,本文对该区的菊科植物进行了系统的分类学研究,在此基础上分析其物种多样性,包括属、种特性,生活型及植物区系地理成分特点等,并对其资源进行归类与评价。研究表明:该区共有菊科植物36属、139种及1亚种和5变种,发现中国帕米尔新纪录属3个(鬼针草属、苦苣菜属、山柳菊属)、以及31个新纪录种和1个变种(异色飞蓬、大叶橐吾、草原婆罗门参等等)。分析该区菊科植物物种多样性发现:单、寡种属占到总属数的83.3%,多种属较少但包含种类较多,占总属数的16.7%和总种数的51.1%;植物生活型以地面芽植物为主,高达85.6%;特有成分比例不高,但中国新疆特有分布种较为丰富。中国帕米尔高原菊科植物区系地理成分多样,温带性质明显,以北温带为主,缺乏热带分布型和中国特有分布型。该区菊科植物资源比较丰富,许多植物在药用、观赏及饲用等方面具有重要价值。本文为帕米尔地区的生物多样性保护、植物资源利用等方面的深入研究提供了基础科学资料。更多还原

【Abstract】 The Pamirs of China locate the southwest of Xinjiang which is a great mountain joint formed by Tianshan Mountain、Kunlun Mountain、Kelakunlun Mountain、and XingDuKu Mountain. It’s position is remote and natural environment is very bad. Compositae is the biggest family in the area, in the paper, we systematically studied taxonomy of Compositae plants, on its basis species diversity was analysed which including the trait of genera and species, life form and flora constitution character and so on. At the end the resource was apprasied and classfied. The research indicated that:There were 36G、139Sp and 1Ssp、5var, including 3 new record genera (Bidens、Sonchus、Hieracium)and 31 new record species and 1 var(Erigeron allochrous Botsch.、L. macrophylla (Ledeb.) DC.、Tragopogon pratensis L. etc)of Chinese Pamirs.According to analysis of species diversity we found autogenus and oligotypic genus wre more , accounted for 83.3% of total genera , multiplicate genus were less but including more species, accounted for 16.7% of total genera and 51.1% of species; In plant life-form, hemicryptoyte plant was main as high as 85.6%. Special ingredient’s proportion was not high, but Chinese Xinjiang unique distribution plant were abundant.The composition of flora of Compositae was very complex in Pamirs of China and the temperate quality was obvious, the north-temperate area was dominating, without tropic distribution and the Chinese unique distribution.Compositae plant resources were rich in the area, many species had important value in medicine、viewing and admiring feeding. Our article provided basic science information for lucubrating how to protect biology diversity and utilize plant resource in Pamirs of China.更多还原
