| 摘 要： | 研究表明,中国喀喇昆仑山地区毛茛科植物有12属28种及2变种;其中寡种属6属,单种属5属,两者占总属数的91.67%和总种数的67.86%,多种属仅1属;其特有现象不是很明显;植物生活型以地面芽植物为主,高达82.14%。其区系成分可划分为4个分布区类型和3个亚型,以温带成分为主,有9属,占总属数的75.0%,所含种数达50.0%,其中,以北温带分布及其变型占首位,其次为旧世界温带分布和温带亚洲分布型,缺乏热带分布型及中国特有分布型。与邻近地区相比,本区毛茛科与中国帕米尔高原的关系最为密切,其属、种相似系数最高,分别达78.57%和65.77%;其次,在属级水平与东喜马拉雅、阿富汗及青藏高原相似性也分别达到55.56%、47.62%、41.38%,但种级相似性系数较低,仅为5.15%~6.45%。

| Abstract: | This paper presents the classification,distribution of Ranunculaceae.About 12 genera,28 species and 2 varieties of Ranunculaceae were recorded in Karakorum mountain of China.There are six oligotypic and five monotypic,accounting for 91.67% of genera and 67.86% of species respectively,and only one multiplicate genus.The proportion of hemicryptophyte is as high as 82.14%.The flora mainly includes temperate elements,which belong to four area-types and three subtypes,accounting for 75.0% of genera and 50.0% of ... |
