摘要
红树林湿地是地球上生产力最高的区域之一,尽管红树林的面积相对较少,但其单位面积的固碳能力很强,是重要的"蓝碳"碳库,其有机碳储量及动态对于全球碳平衡有重要影响。本文对红树林湿地有机碳(包括植被生物量碳和沉积物有机碳)的碳储量及计量方法,沉积物中有机碳的组成、来源及溯源方法,以及影响红树林湿地有机碳动态的因素等方面的研究进行了综述,并对其存在的问题和今后的研究趋势进行了分析。基于红树林湿地的固碳潜力和资源快速减少的现状,准确评估红树林碳库及其动态,有助于气候变化框架条约下的滨海湿地碳计量和价值评价,可以揭示红树林生态系统与全球变化的反馈关系,为红树林生态恢复和保护提供依据。
Mangrove wetland is one of the most productive ecosystems in the world. Its occupied area is not vast, but its carbonsequestration capability per unit area is quite strong, being an important ‘blue carbon’ sink, and the storage and dynamics of the organic carbon in the sink having great effects on the balance of global carbon cycle. In this paper, the present research progress on the organic carbon storage （including that of vegetation biomass and sediment） in mangrove wetlands and related measurement methods, the components and source of the sediment organic carbon, and the factors affecting the dynamics of the organic carbon in mangrove wetlands were summarized, and the existing problems and future research trends were analyzed. In terms of the rapid decline of the carbonsequestration capability of mangrove wetland and the rapid decrease of the wetland resource, it would be necessary to accurately assess the carbon sink and its dynamics of mangrove forests, which would contribute to the carbon measurement and valuation of coastal wetlands under the treaty of climate change framework, help to reveal the feedback relationships of mangrove ecosystem and global change, and provide a basis for the restoration and protection of mangrove ecosystems.
