珊瑚移植被认为是增加退化珊瑚礁珊瑚丰度的主要手段之一。为探讨珊瑚移植的不同方法和品种对移植效果的影响，在海南三亚湾鹿回头珊瑚礁过度开发、受人为活动和自然灾害威胁的海域，采用4种方法移植了5种珊瑚（n=902）。移植后10个月，移植珊瑚的平均存活率为45.5%。方法对移植珊瑚有不同的影响，但没有一种方法对所有珊瑚物种都有效。方法学不能改变叶状表孔珊瑚和鹿角珊瑚的下降趋势，但可以减缓其下降。所有移植的A.风信子M.小叶藻死亡率高，存活面积显著减少，滨珊瑚、芦苇和束状乳珊瑚死亡率低，部分死亡。只有一种方法能显著提高G. fascicularis，与P.安德鲁西。在5种移植珊瑚中，只有Pocilloppora damicornis在所有应用方法中活组织面积增加，而其他珊瑚在一种或多种方法中活组织面积减少。这项研究的结果表明，在一个高度受威胁的地区进行珊瑚移植是没有效率的，除非威胁被减少或消除。此外，为珊瑚移植选择适当的物种至关重要，特别是在受干扰的环境中。方法学虽然对珊瑚移植效果的改善有限，但无法补偿鹿回头礁脆弱物种对压力的适应不良。在鹿回头礁进行珊瑚移植时，应首先考虑移植对环境耐受性好的珊瑚。
Coral transplantation is considered as one of the major tools to increase coral abundance for degraded coral reefs. To investigate the effects of various methods and coral species in transplantation, coral fragments (n=902) of five coral species were transplanted by four methods at Luhuitou, the Sanya Bay, Hainan Province, China, where the reef has been over-exploited and is still threatened by human activities and natural disasters. Ten months after the transplant, the average survivorship of the transplanted corals was 45.5%. Methodologies had different effects on the transplanted corals, but none of them was efficacious for all coral species. Methodology could not change the decreasing trend forMontipora foliosaandAcropora hyacinthus, although it did slow down their decline. All transplants ofA. hyacinthusandM. foliosahad high mortalities and significant decrease on survival area, whilePorites andrewsiandGalaxea fascicularishad lower mortalities and partial mortalities. Only one method had significant effect on increasing survival area ofG. fascicularis, same asP. andrewsi. Out of the five transplanted coral species,Pocillopora damicorniswas the only species that had living tissue area increase in all applied methods, while the others had decreased live tissue area in one or more methods. The results of this study suggested that performing coral transplantation in a highly threatened area was not efficient unless the threats were diminished or erased. Moreover, proper species selection for coral transplantation is crucial, especially in a disturbed environment. Methodology, although having limited effects on improving results of coral transplantation, cannot compensate the maladjustment of vulnerable species to the stresses on the Luhuitou Reef. Coral transplantation on Luhuitou Reef should not be performed unless the stresses are under controlled, and corals with good tolerance to the environment should be considered first.
