我们对森林覆盖的低地热带泥炭地的碳库和交换通量的了解有限，这是我们对全球碳循环理解的一个主要空白。几个地区（例如刚果盆地、亚马逊河流域的大部分地区）的泥炭矿床才刚刚开始绘制地图和描述特征。在这里，我们考虑在何种程度上方法的改进和改善研究人员之间的协调，可以帮助填补这一空白。我们回顾了文献测量的关键参数计算碳库和通量，包括泥炭地面积，泥炭体积密度，碳浓度，地上碳储量，凋落物输入泥炭，气态碳交换和水碳通量。我们确定了特别需要进一步研究和更好协调的领域，以减少热带泥炭地碳库和通量估计的不确定性，从而促进对这些异常富碳生态系统的更好管理。
Our limited knowledge of the size of the carbon pool and exchange fluxes in forested lowland tropical peatlands represents a major gap in our understanding of the global carbon cycle. Peat deposits in several regions (e.g. the Congo Basin, much of Amazonia) are only just beginning to be mapped and characterised. Here we consider the extent to which methodological improvements and improved coordination between researchers could help to fill this gap. We review the literature on measurement of the key parameters required to calculate carbon pools and fluxes, including peatland area, peat bulk density, carbon concentration, above-ground carbon stocks, litter inputs to the peat, gaseous carbon exchange, and waterborne carbon fluxes. We identify areas where further research and better coordination are particularly needed in order to reduce the uncertainties in estimates of tropical peatland carbon pools and fluxes, thereby facilitating better-informed management of these exceptionally carbon-rich ecosystems.
