| 摘要: |
| 红树植物红榄李[Lumnitzera littorea(Jack.)Voigt]在我国现存仅有359株左右,全部分布在海南,极度濒危。具体地点为三亚铁炉港(9株)、陵水大墩村(约340株)、海口的东寨港(10株,移植)。只有陵水的红榄李在一定程度上具有自我繁殖能力。红榄李具有双花期,可与榄李(L.racemosa)混生。红榄李种子萌发率低,人为干扰严重是影响红榄李种群生存的主要原因。建议把陵水大墩村红树林分布区设为保护区,恢复红榄李生境,抢救我国目前唯一一处尚具有自我繁殖潜力的红榄李野生种群。 |

| Abstract: |
| Field investigations revealed that there are merely about 359 Lumnitzera littorea (Jack.) Voigt mangrove trees in China, extremely endangered, locating at Tielu Bay (9 trees), Dadun village of Lingshui county (about 340 trees) and Dongzhai Bay (10 trees, transplanted) in Hainan province.Only the trees in Lingshui have self-reproduction ability to a certain extent.Bi-florescence and mixed growth with L.racemosa was firstly observed for L.littorea.The main causes of threatening the survivorship of L.littorea population are low germination rate of seed and severe human interferences.In addition, some suggestions were brought forward to rescue and breed China L.littorea species. |
