| 摘 要： | 越南植物区系以热带分布的科和属为其主体成分,是热带性质的植物区系,属于热带亚洲植物区系的一部分,但带有大陆东南亚热带北缘性质和特点,与热带亚洲核心区植物区系有一定差异.在与中国热带北缘和马来西亚地区植物区系的比较上,越南植物区系与海南植物区系科相似性达90.8%,属相似性达85.7%,与马来半岛植物区系科相似性达94%,属相似性达69.4%.无论在优势科还是在代表科的组成上,越南植物区系都与中国热带北缘植物区系最接近,同属于热带亚洲植物区系的热带北缘类型.

| Abstract: | The flora of Vietnam is composed mainly by tropical families and genera, and is of tropical in nature. The Vietnamese flora is therefore considered to be part of tropical Asian flora. In comparison with the flora of southern China and that of Malesia, the Vietnamese flora shows higher floristic similarity to the tropical flora of southern China. The similarity coefficients at family and generic levels are 90.8% and 85.7% between the flora of Vietnam and the flora of Hainan of SE China respectively, and 94% and 69.4% between the Vietnamese flora and the flora of Malay peninsula respectively. The Vietnamese flora, which is more similar to the tropical flora of southern China in both the families with species richness and the representative families, is a marginal type of the tropical Asian flora from the mainland SE Asia. |
