摘　　要：为了解湖南壶瓶山草本植物区系特点,发掘适合墙体绿化应用的草本植物,在壶瓶山通过野外实地调查和文献整理统计,发现壶瓶山共有草本植物100科546属1 363种,优势科、优势属明显,且单种属占比高。从科属级别分析了该区草本植物区系特征:科的分布型倾向于热带成分(37%),并以泛热带分布科为主(13.18%),而属的分布型温带成分(54.02%)明显多于热带成分(35.73%),整体上中亚热带的植物区系特征明显,区内古老孑遗属众多,区系组成成分复杂。该区能运用于墙体绿化的多为禾本科、荨麻科、景天科植物,虽然特有成分多,草本植物丰富,但很多具有墙体绿化和园林应用价值的草本植物没有被充分认知和利用。In order to understand the characteristics of herbaceous flora in Huping mountain, Hunan province, and analyze its application in wall greening. Taking Huping mountain in Hunan province as an example, there are 1363 species of herbaceous plants belonging to 546 genera and 100 families in Huping mountain, Hunan province. The dominant genera and dominant genera are obvious, and the proportion of single species is high. The floristic characteristics of the flora in this area were analyzed from the family level. The distributional patterns of the families tended to be tropical components (37%) and that of the pantropical families (13.18%). However, the distribution of genera tends to be more temperate (54.02%) than that of tropical (35.73%). There are many ancient relict genera and complex floristic components in the zone. The plants of Gramineae, Urticaceae and Sedum can be applied to wall greening in this area. Although there are many endemic components and abundant herbaceous resources, the plants with garden application value have not been recognized and utilized.
