| 摘 要： | 地处桂西南的那坡县迄今计有种子植物174科，889属，2201种。其中东亚特有科5个，中国特有属15个，那坡特有种39个。这一地区不仅植物种类丰富，而且特有现象较为显著。在15个中国特有属中，1属为那坡本地的的特有属，4属为苦苣苔科植物。中国特有种的各亚型以及39个那坡特有种所隶属的分布区类型的分析均表明，该植物区系具有强烈的热带亚洲特色。石灰岩山地的特有文化发展则是那坡植物区系的另一个显著特征，这种特有化发展在苦苣苔科中表现得尤为显著。

| Abstract: | There are 2201 species in 889 genera and 174 families of seed plants in Napo County which is located in the southwest of Guangxi Province.Among them,5 families are endemic to East Asia, 15 genera to China and 39 species to Napo County.The results show that this region is rich in plant taxa and endemism.Among the 15 genera endemic to China,1 genus endemic to Napo County and 4 genera belong to Gesneriaceae.In the specific level,we analysed the areal subtypes of the Chinese endemic species and areal types of the genera to which the 39 species endemic to the region belong,the results all show that this flora has strongly tropical and subtropical characters.Endemism developed in the limestone regions of Napo County shows that a remarkable feature.This phenomenon is conspicous in Gesneriaceae. |
