摘要:

热带岛屿的植物多样性一直是全球生物多样性保护的重点和热点。海南岛地处热带北缘, 是中国的第二大岛屿, 具有丰富的植物多样性。经过近几十年的考察研究, 关于海南岛的植物物种数量出现了多个版本。本文通过文献梳理和野外考证的方法进行了全面的植物多样性调查, 以确定其维管植物种数。结果表明: 截止到2015年12月, 海南岛记录并能考证实物或标本的维管植物共有6,036种, 包括野生种4,579种(含特有植物483种和珍稀濒危植物512种)、外来逸生及归化植物163种(含外来入侵种57种)、外来引种的纯栽培植物1,294种。自1964-1977年《海南植物志》出版至今, 新增野生及引种的栽培植物所占的比例均较大, 分别占海南岛野生和栽培植物总种数的35.9%和75.9%。本文还对其中1,220种的拉丁学名进行了异名处理等的订正。

Abstract:

Maintaining plant diversity on tropical islands is a priority for biodiversity conservation. Hainan Island, located in the northern tropics, is the second largest island in China with high plant diversity. Several updated plant lists of local flora have been published after decades of field investigations. In this paper, we investigated the plant diversity on Hainan Island by conducting extensive field surveys and a literature review. Results indicated that, as of December 2015, there were 6,036 vascular plants recorded on Hainan Island with voucher specimens or practical materials. Among these species, 1,220 species were revised as synonymously, 4,579 species were wild (including 483 endemic and 512 rare and endangered species), 163 were naturalized species (including 57 invasive species) and 1,294 species were cultivated species. Since the publication of Flora Hainanica in 1964-1977, a large proportion of newly recorded species were mainly wild or introduced species, and accounted for 35.9% and 75.9% of their corresponding totals, respectively.
