中国3种濒危红树植物的分布现状

Current distributions of three endangered mangrove species in China

在海南岛东部沿海对我国3种濒危红树植物红榄李、莲叶桐和水芫花分布现状开展调查,得出红榄李在三亚铁炉港分布有9株,处于老龄或接近老龄林阶段;陵水新村港仅分布有38株,该地红榄李遭破坏严重。两地红榄李均可正常开花结果,但林下并无幼苗发育。莲叶桐主要自然分布在琼海博鳌和潭门,共223株;文昌自然分布5株,东寨港人工栽植4株,两地莲叶桐均仅开花,未结果。水芫花分布于文昌市会文镇,共有23株,均正常开花结果,种子能够萌发,但难以成苗。调查结果将有助于提出相应的保护和恢复措施。

The current distributions of three endangered mangrove species Lumnitzera littorea （Jack.） Voigt, Hernandia nymphiifolia （Presl） Kubitzki and Pemphis acidula J R ＆ G Forst in China were investigated in east coast of Hainan Island. There were nine trees of L littorea in the Tielu Bay Sanya, and they were in the old or near old growth forest stage. Only 38 trees distributed in the Lingshui Village, which were severely damaged. L. littorea in the two places could bloom normally, but there were no seedlings. Totally 223 H. nymphiifolia trees distributed naturally in the Qionghai Boao and Tanmen. Five trees naturally distributed in the Wenchang, and four trees were artificially grown in the Dongzhaigang. They could not fruit but flower in these places. There were totally 23 trees of P acidula in the Huiwen Wenchang, and they could flower and fruit. The seeds could germinate, but were difficult to grow. The results are useful in making appropriate protection and restoration measures.
