| 摘要: |
| 调查敢壮山植物多样性,采集和鉴定植物标本,编制植物名录,分析研究敢壮山的植物区系。结果表明,敢壮山有野生种子植物75科,207属,254种。科以泛热带成分为主(占58.7%),其中科的热带性成分占66.7%。属以泛热带分布最多(占34.57%),属热带性成分占78.72%。敢壮山植物区系的表征科主要有葡萄科(Vitaceae)、防己科(Menispermaceae)、漆树科(Anacardiaceae)、桑科(Moraceae)、荨麻科(Vriticaeae)、鸭跖草科(Commelinaceae)等,它们大多是泛热带分布科。敢壮山的植物区系起源古老,热带成分优势明显,具有热带过渡到亚热带的性质,但是区系的特有程度较低。 |

| Abstract: |
| This paper investigates the plant diversity,collects and identifies the plant specimen,compils the plant catalogue,and analyzes the flora of Ganzhuang mountain.The results show that there are 254 species of wild seed plants which belong to 207 genera and 75 families in Ganzhuang mountain.Based on their geographical distribution,75 families are classified into 8 areal-types,among them Pan tropical element is dominant(58.7%),and the tropical elements make up 66.7%.207 genera are classified into 14 areal-types,among which Pan tropical element is dominant(34.57%),and the tropical elements make up 78.72%.The representative families are Vitaceae,Menispermaceae,Anacardiaceae,Moraceae,Vriticaeae,Commelinaceae,etc.They are mainly Pantropic distribution.The flora,originating in Ganzhuang mountain a long time ago,features peculiar tropical advantages,tropics-subtropics transition,but low typical flora. |
