摘要：

通过实地调查和文献资料查阅,对成吉思汗陵周边野生种子植物区系特征、生活型和水分生态型进行分析。结果表明:成吉思汗陵周边有野生种子植物529种隶属260属73科,分别占内蒙古种子植物的23.96%,39.82%,62.39%,在属、种层次上多样性较贫乏;植物科属组成特点是趋向大科、大属分布,寡种科属和单种科属是植物区系主要组成成分,也是植物区系构成和物种多样性的重要来源;区系地理成分混杂,联系广泛;属的分布区类型中温带成分优势明显,泛热带分布次之;特有程度低,表现出一定的古老性;植物生活型以草本植物占绝对优势,占总种数的86.39%;水分生态型以中生植物为主,占总种数的62.38%。

Abstract:

Based on field survey and literature references, the features of flora, life forms and water ecotypes of wild seed plants were analyzed in the surrounding Mausoleum of Genghis. Results show that there are 529 species, 260 genera and 73 families in the surrounding mausoleum of Genghis Khan, which reached 23.96%, 39.82% and 62.39% of total seed plants in Inner Mongolia, indicating that the levels of genera and species diversity are not abundant. The species composition is characterized by most species trend to distribution in the large families and genera, the mid-specific family, mid-specific genera, mono-specific family, and mono-specific genera are the main part of flora, the main sources of flora constitute and species diversity. Geographic elements of the flora were complex and numerous. The temperate element characteristics were the typical features of local flora, followed by pantropic. There are few Chinese endemic genera and some antiquity. In life forms of the species, the herbs had absolute superiority, which account for 86.39% of the total species of the seed plant. In water ecotypes of the species, the mesophytes account for 62.38% of the seed plant.

Key words: Spermatophyte, Floral, Life form and water ecotype, The surrounding mausoleum of Genghis Khan
