中国渚碧岛和永暑岛维管植物调查

为了解南沙渚碧岛和永暑岛的维管植物的情况，笔者于2019年8月对南沙渚碧岛和永暑岛的植物种类、生长情况和来源类型进行调查。调查结果表明，南沙渚碧岛和永暑岛上共有维管植物有48科145属176种（含变种和变型），其中渚碧岛有45科131属156种，永暑岛有41科94属105种，与2012年的调查记录比较，植物数量和植物多样性均有大量增加。根据西沙群岛植被植物的生长状况和来源类型，结合2018年调查美济岛的情况，提出合适南沙岛礁植物的引种策略，为保持岛礁植物群落生态平衡、绿化美化南海岛礁促进军民融合提供参考。

A Survey of Vascular Plants in Zhubi and Yongshu Islands,China

A survey was made of the vascular plants in Zhubi Island and Yongshu Island, Nansha Islands, the southernmost of China in August 2019 in terms of species, growth status and source. The survey showed that there were 176 species (including variety and form) of vascular plants in these two islands, belonging to 145 genera and 48 families, of which 156 species were under 131 genera and 45 families in Zhubi Island and 105 species under 94 genera and 41 families in Yongshu Island. The vascular plants in this survey were much higher in number and diversity than those recorded in 2012. Based on plant species recorded in the surveys in neighouring Meiji Reef and Xisha Islands, some plant species were proposed to be planted for wind break, sand fixation or greening, or as edible herbs, vegetables or fruits in Nansha Islands to maintain ecological balance of plant communities and greening, provide vegetable supply and promote military and civilian integration in Nansha Islands in the future.
