中国喀喇昆仑山菊科春黄菊族植物研究

Plant Research of Anthemideae in Karakorum Mountains in China

在野外实地考察的基础上,结合查阅有关标本,对中国喀喇昆仑山菊科春黄菊族植物进行了形态分类学研究.结果表明:中国喀喇昆仑山菊科春黄菊族共有5属28种2变种,分别占该区菊科植物属种总数的20.0%和30.8%;其中中国喀喇昆仑山新记录种2种——羽叶扁芒菊[Waldheimia tomentosa(Decne.)Regel]与草原绢蒿[Se-riphidium schrenkianum(Ledeb.)Poljak],无本区特有种与仅分布种.该区春黄菊族植物寡种属占优势,但种级水平多种属(蒿属ArtemisiaL.)种数占优势;植物区系以温带性质为主,占总属数的80.0%;植物生活型以地面芽和地上芽植物为主,占总种数的92.8%.

In this paper,the classification of Anthemideae of Compositae in Karakorum Mountains in China were researched based on the field and specimen collection investigation.About 5 genera,28 species and 2 varieties of Anthemideae are recorded to occur in Karakorum Mountains in China,respectively,which are accounting for 20.0% of genera and 30.8% of species in Compositae in this area.Among them,there are 2 new recorded species that is Waldheimia tomentosa （Decne.） Regel and Seriphidium schrenkianum （Ledeb.） Poljak in Karakorum Mountains in China.But there are no species which are endemic and only distribute to this area.Monotypic genera is in the ascendant of Anthemideae in this area.On the level of species,polytypic genus Artemisia L.is in the ascendant.The main distributlon-type of genera in Anthemideae is temperate nature in this area,accounting for 80.0% of total genera.The 92.8% of species of Anthemideae in this area are Hemicryptophytes and Chamaephytes,and therefore they are the dominating components in the plant life form spectrum in this area.
