Abstract:

In this study, according to a 3-year filed work, plenty of herbariums, and documents in several universities, we analyzed the structure and flora characteristic of spermatophyte genera in order to understand the origin and evolution of spermatophyte in Mongolian plateau. The results showed that there were 4 280 species belonging to 115 families and 761 genera in Mongolian Plateau. Spermatophyte flora in this area was less than that in Chinese flora. Regional flora had typical temperate element characteristics in Mongolian Plateau. Floristic geographical elements were complex and had extensive relationship with others. Spermatophyte flora of Mongolian Plateau had some phylogenetic relations with tropical element. Monotypic and oligotypic genus were the main parts of the local flora, and dominant genus were not significant. Both xeromorphy and antiquity were significantly dominant in the flora. According to floristic genesis, the origin of Mongolia plateau spermatophyte was linked with Ancient Mediterranean, East Asia, temperate elements, and local origin.

Key words: Spermatophyte, Structure of Genera, Geographical element, Origin and evolution, Mongolian Plateau

摘要:

通过3年的实地调查,查阅多个标本馆标本及相关资料,研究了蒙古高原种子植物属的组成和区系特征,以期探讨其起源与演化。结果表明:该区有种子植物115科761属4 280种,与中国植物区系相比,本区种子植物区系物种相对贫乏,特有程度较低;区域植物具有典型的温带性质,其区系地理成分复杂,联系广泛,与热带成分具有一定的亲缘关系。植物区系优势现象不显著,以单型属和少型属为主。蒙古高原植物区系表现出强烈的旱生性和古老性。从植物区系发生角度分析,蒙古高原植物区系的起源可归结为古地中海成分、东亚成分、温带成分和本地起源。
