• 摘要：珊瑚礁是海洋生态系统的重要组成部分，具有食物资源、药用价值、海岸防护等生态功能.近年来受到自然气候及人类活动的影响，珊瑚礁生态系统发生了大规模的退化，因此，珊瑚礁生态修复技术逐渐成为研究热点.本文从Web of Science核心合集、CNKI、德温特数据库等获得相关文献，对全球及国内珊瑚礁生态修复技术研究热点进行全面分析.结果表明：目前珊瑚礁生态修复技术主要分为生物修复和生境修复两大类，其中，生物修复以无性繁殖为主，虽然无性繁殖技术成本相对较低，但有性繁殖技术更容易维持生物多样性，提升珊瑚礁生态系统对环境扰动的恢复力和弹性；珊瑚礁生态修复技术监测时间大多小于18个月，移植珊瑚存活率低，存活率中位数为60%~70%，修复规模小，修复区以单一的珊瑚礁生态系统为主.发展生物修复与生境修复相结合的生境连通修复技术，提高局部海域群落连通程度，实现红树林、海草床及珊瑚礁等不同生态系统间营养循环与物质流动，可成为提高关键珊瑚种群恢复效率、提升生态系统健康（结构、活力、组织力）的重要手段.

• Abstract：Coral reef is one of the most important marine ecosystems， providing significant ecological goods and services， such as food， medicinal materials， and shoreline defenses to human being. However， in recent years， coral reef ecosystems have undergone serious degradation due to natural climate change and anthropogenic perturbations， and then ecological restoration technology for coral reef has gradually become one research hotspot. By using the method of bibliometrics， the paper analyzed the research hotspots of ecological restoration technology for coral reef， which were from the Web of Science core collection， CNKI， Derwent database， etc. There are two kinds of technologies for the coral reef restoration， including bioremediation and environmental restoration. Asexual reproduction is the mainstream of the bioremediation technologies with cost-effective advantage. Otherwise， sexual reproduction from the bioremediation technologies get more attention， which is tend to maintain the gene diversity and biodiversity of coral ecosystem， and improve the resilience of coral ecosystem. The monitoring time scale of coral reef ecological restoration technology is mostly less than 18 months， and the survival rate of transplanted coral is low with the median of 60%~70%. The remediation area is often small， which is dominated by a single coral reef ecosystem. Bioremediation and habitat restoration should be combined in future remediation project. Developing habitat connectivity restoration technology can improve the connectivity of local sea biological communities， increase biological abundance and diversity， and promote the overall nutrient cycle and material flow of among the multiple ecosystems， such as mangroves， seagrass beds， and coral reef ecosystems. It benefits to improve the health （structure， vitality and organization） of coral reef ecosystems， and achieve the goal of improving repair efficiency.
