| 摘 要： | 特有植物是了解一个地区植物区系的起源与演化规律的关键。对海南岛石灰岩特有植物的地理分布特征和分类的初步研究表明:本区共有石灰岩特有植物63种,隶属于37科52属,其中热带性的属占的比例较高;属于海南石灰岩专性种的有18种,一些种类对生长基质的要求相当严格。与其它地区比较,石灰岩山地的特有化发展在海南不很明显。从特有植物的分布来看昌江是海南一个重要的石灰岩植物分化中心。对海南石灰岩特有种比例较低的原因和保育进行了探讨。

| Abstract: | Endemic plants occurring in limestone of Hainan Province consist of 63 species in 52 genera and 37 families, of which 18 species are restricted to Hainan only. About 84% of the species are of tropical elements. Changjiang County of western Hainan is considered to be the centre of the distribution of endemic plants on theisland. However, endemism in the limestone flora of Hainan is not obvious as compared to that of neighboring Provinces. A list of endemic species distributed in limestone region on Hainan is tabulated. |
