| 摘 要： | 在对海南岛南端与北端沿海低山丘陵植物区系进行实地调查的基础上，对两个地区植物物种组成进行了比较研究。结果显示两地物种组成既有相似性也有差异性：琼南有种子植物876种，隶属于112科484属，植物区系以热带成分为主，兼有一定的温带成分和中国特有成分，且海南特有成分较高，具有一定的过渡性；琼北有种子植物934种，隶属于141科580属，植物区系以热带分布类型为主，同时有一定的温带成分，海南特有成分较高；两地植物区系的共同点是：均具有种类丰富、地理成分多样、优势成分明显、热带性质较强等。

| Abstract: | Located in the north-edge of tropical Asia, the flora of Hainan Island has ancient tropical floristic compositions as well as ancient subtropical floristic compositions of China, due to its diversity of natural landforms and climate. In this paper,we chose coastal and hilly areas such as Liudaoling Nature Reserve, Huoling Nature Reserve, Luhuitouling Mountain, Nanshanling Mountain and Hongxialing Mountain （which all locate in the southern Island and are called QN below） , and Tongguling Nature Reserve （which lo- cates in the northern Island and is called QB below） as research areas. After surveying the plots,we obtained enough data and compared floristic compositions of two areas. Results show that floristic compositions of both areas had similarities and differences ： In QN, there are 876 species of spermatophyte, belonging to 112 families and 484 genera. Geographic elements include tropical ones, temperate ones and Chinese endemic ones. Tropical elements are dominant and Hainan endemic ones are rich, which shows it is transitional elements;In QB, there are 934 species of spermatophyte, which belong to 141 families,580 genera. Geographic elements, which include tropical ones, temperate ones and endemic ones, are dominated by tropical elements and rich in Hainan endemic elements. The common characteristics of flora components of two areas are that plant species are abundant, geographic elements are diversified, dominant elements are significant and proportion of tropical elements is high. |
