红树林是世界上生产力最高的生态系统之一，并提供基本的生态系统服务，如通过固碳来调节全球气候。详细了解沿海生态系统之间的生态系统连通性驱动因素(在悬浮颗粒有机物交换方面)的影响，如地貌环境和碳储量，对于能够描述碳动态是很重要的。在这里，我们比较了红树林-海草-潮滩海景中的碳储量、沉积物-空气界面的二氧化碳通量、溶解有机碳和悬浮颗粒有机碳的浓度。利用碳、氮的稳定同位素特征，结合MixSIAR模型，评估了不同来源的有机质在不同海景成分中的贡献。一般情况下，溶解有机碳的碳浓度高于悬浮颗粒物。不同地点的地貌环境反映了初级生产者对颗粒状有机质的贡献。例如，河边地区的最大贡献者是红树林和陆地植物，而在边缘地区，海洋和大型藻类来源占主导地位。人为引起的沿海变化(即红树林面积的减少)可能会影响邻近沿海生态系统的碳积累动态。
Mangrove forests are among the world’s most productive ecosystems and provide essential ecosystem services such as global climate regulation through the sequestration of carbon. A detailed understanding of the influence of drivers of ecosystem connectivity (in terms of exchange of suspended particulate organic matter), such as geomorphic setting and carbon stocks, among coastal ecosystems is important for being able to depict carbon dynamics. Here, we compared carbon stocks, CO2fluxes at the sediment-air interface, concentrations of dissolved organic carbon and suspended particulate organic carbon across a mangrove-seagrass-tidal flat seascape. Using stable isotope signatures of carbon and nitrogen in combination with MixSIAR models, we evaluated the contribution of organic matter from different sources among the different seascape components. Generally, carbon concentration was higher as dissolved organic carbon than as suspended particulate matter. Geomorphic settings of the different locations reflected the contributions to particulate organic matter of the primary producers. For example, the biggest contributors in the riverine location were mangrove trees and terrestrial plants, while in fringing locations oceanic and macroalgal sources dominated. Anthropogenic induced changes at the coastal level (i.e. reduction of mangrove forests area) may affect carbon accumulation dynamics in adjacent coastal ecosystems.
