亚热带泥炭地作为甲烷气体来源的作用还没有得到很好的理解，部分原因是环境控制气体沸腾模式的不确定性。过去的研究已经指出了一系列的环境因素控制沸腾，虽然我们已经发现，沸腾模式可以复制的模型只考虑物理参数的泥炭基质。在这里，我们测试了一个计算机模型的气体沸腾和存储对自然系统的第一次，使用一套现场测量在佛罗里达沼泽地。模拟的沸腾显示出类似的模式，在现场观察到的频率分布和幅度，特别是从较高密度的泥炭织物的地区。这些结果表明，泥炭土的内部结构是一个重要的控制沸腾在沼泽地的空间和时间模式，调查沸腾模式的环境控制时，应考虑。
The role of subtropical peatlands as a source for methane gas is not well understood, partly due to uncertainties surrounding environmental controls on gas ebullition patterns. Past studies have pointed to an array of environmental factors controlling ebullition, although we have found that ebullition patterns can be replicated by a model considering only physical parameters of the peat matrix. Here we tested a computer model for gas ebullition and storage against a natural system for the first time, using a suite of field measurements in the Florida Everglades. Modeled ebullition showed patterns similar to those observed in the field in terms of frequency distribution and magnitude, specifically from areas of higher density peat fabric. These results suggest that the internal structure of the peat soil is an important control on spatial and temporal patterns of ebullition in the Everglades and should be considered when investigating environmental controls on ebullition patterns.
