摘要: 海南岛现有蕨类植物种数约400 种, 分布基本上呈现西南部丰富, 东北部贫乏的趋势, 临高- 琼中- 万宁一线是其物种多寡的分界线, 土壤、地形、地质多方面的共同作用形成这条分界线。海南岛蕨类区系组成复杂, 且外来植物成分占据多数, 马来西亚、印度、中南半岛和东亚植物区系成分在海南岛蕨类区系中占有较大比重。海南岛是现代蕨类发育的一个中心, 多样的环境条件促成了蕨类植物的演化。

Abstract: There are nearly 400 fern species in Hainan Island. The pteridoflora is richer in the southwest and poorer in thenortheast in this Island. A line from Lingao, Qiongzhong, to Wanning is the boundary of the richer and the poorer regions. Soil terrain and geology′s co-action form this line. The foristic elements are complex, and the majority are closely related to foreign pteridofloras. Malayan, Indian, Indochinese and East Asian play important roles in fern flora of Hainan Island. It may be a modern centre of differentiation for pteridophytes. Various natural environments accelerate local ferns′evolution.
