沿海湿地是土壤碳(C)的大型储存库。然而，对这些系统中碳贮量的年累积率尚未在大尺度上进行空间估计。我们合成了毗邻的美国(US)潮汐湿地的碳累积速率(CAR)，将CAR提升到全国范围，并根据气候变化情景预测了趋势。结果表明，CAR平均值为161.8 ± 6g cm−2yr−1，而邻近的美国潮汐湿地的CAR为4.2~5.0Tg Cyr−1。潮汐湿地汽车预计将在本世纪增加，并在所有气候变化情景下继续其C固着能力，这表明对海平面上升有很强的适应能力。这些结果是对美国潮汐湿地碳积累的基线评估，并表明本世纪有一个重要的碳汇。
Coastal wetlands are large reservoirs of soil carbon (C). However, the annual C accumulation rates contributing to the C storage in these systems have yet to be spatially estimated on a large scale. We synthesized C accumulation rate (CAR) in tidal wetlands of the conterminous United States (US), upscaled the CAR to national scale, and predicted trends based on climate change scenarios. Here, we show that the mean CAR is 161.8 ± 6 g Cm−2yr−1, and the conterminous US tidal wetlands sequestrate 4.2–5.0 Tg C yr−1. Relative sea level rise (RSLR) largely regulates the CAR. The tidal wetland CAR is projected to increase in this century and continue their C sequestration capacity in all climate change scenarios, suggesting a strong resilience to sea level rise. These results serve as a baseline assessment of C accumulation in tidal wetlands of US, and indicate a significant C sink throughout this century.
