| 红树林是具有重要碳汇功能的生态系统，其保护和修复成为海洋领域应对气候变化的重要手段。适宜的生境条件是红树林生态修复成功与否的关键因素，而红树植物物种和种植措施等也决定了修复后生态系统结构和功能的发展。本研究综述了红树林生态修复固碳功能的特点，分析了生境条件、物种和种植措施等因素对红树林生态系统固碳效果的影响，以期为红树林生态修复提供参考。总体上，红树林生态修复促进了有机碳在植物体和土壤中的累积，而在生态修复初期红树植被的固碳能力高于土壤。水文条件、滩涂高程、底质条件、物种、种植密度和种苗来源等关系到修复后红树植物的生长、颗粒态有机物的沉降、有机物的输出和保留、有机质的分解等过程，进而影响生态系统的固碳能力。因此，开展红树林生态修复时选择适宜生境条件的修复地块，合理选择物种和种植措施，在提高植被恢复效果的同时可提高红树林固碳增汇的生态功能。 |

| Abstract: |
| Mangrove wetlands play an important role in carbon sequestration and their conservation and restoration are recognized as an important solution for the climate change in coastal area. The success of mangrove wetland restoration depends on whether the environmental settings support the survival of mangrove seedlings. The mangrove species and the plantation mea-sures also determine the development of ecosystem structure and functions after restoration.In this paper, we overview the behaviors of carbon sequestration in the restored mangrove wetlands and also summarize how carbon sequestration varies with the environmental settings, mangrove species and plantation measures. Generally, hydrological condition, tidal elevation, soil texture, mangrove species, plantation density and seedling source will affect the processes of plant growth, the sedimentation of particle organic materials, the retention, exportation and decomposition of organic materials, and thus the capability of carbon sequestration. Therefore, in order to improve the effect of vegetation restoration and the ecological function of carbon sequestration of mangrove, the suitable land for ecological restoration, the right species and plantation measures should be selected. |
