海南岛吊罗山地区珍稀濒危植物区系研究

Study on the flora of rare and endangered plants of Diaoluoshan Mountain in Hainan island

吊罗山地区有"红皮书"保护植物34种,"国家重点"保护植物33种,隶属8个属分布区类型、4个种分布区类型。以热带成分的属占优势,热带亚洲分布类型所占的比例最大;特有成分较突出,特有种隶属于3个分布类型,以华南分布为中心。吊罗山与五指山、尖峰岭的种、属相似程度高,其中与五指山的相似度最大。吊罗山珍稀濒危植物可用作园林、药用、木材、农业资源植物,多分布在低、中海拔的湿润密林或沟谷林中,对森林依赖性很强,要采取相关措施对这些物种及其生境进行保护。

There are 34 species of conservation plants listed in the Chinese Plants Red Data Book and 33 ones listed in National Key Protected Wild Plants List respectively in Diaoluoshan Mountain. The geographic elements of them consist of 8 genera of distribution types and 4 species of distribution types. Moreover, tropical elements are dominant and proportion of tropic Asia ones is the largest among genera. Meanwhile, endemic species are prominent and they are attributed to 3 distribution types, and their distribution centre is mainly in southern China. Compared with Wuzhishan Mountain and Jianfengling Mountain, species and genera of rare and endangered plants in Diaoluoshan Mountain are greatly similar with them, and have the greater similarity with Wuzhishan Mountain than with the other. The rare and endangered plants in Diaoluoshan Mountain area can be used for gardens, drugs, timbers and agricultural resources ones, they mainly distributed in humid jungles or valley forests with low or medium altitude, and greatly depend on forest habitat. Some related measures should be taken to protect these species and their habitats.
