测算方式对土壤呼吸通量的影响

Effect of Measuring Methods on Soil Respiration Fluxes

摘要: 土壤呼吸作为全球碳循环的重要组成部分，它变异性的复杂过程会受到陆地生态系统中多种因素的调控。而对于全球碳循环周期的研究，科研人员经常会运用到一些经验模型来模拟。与基于过程的模型相比，这些模型更方便简单，需要的特定于现场的变量也更少。本研究选择了三种常用于测算土壤呼吸通量的方法对蒙古栎林土壤呼吸通量进行数据模拟分析。尝试探讨三种方法的优缺点，以期为相关领域的研究提供一定的参考价值。

Abstract: As an important part of the global carbon cycle, the complex process of soil respiration variability is regulated by many factors in the terrestrial ecosystem. For the study of the global carbon cycle, researchers often use some empirical models to simulate. Compared with process-based models, these models are more convenient and simpler, and require fewer field-specific varia-bles. In this study, three methods commonly used to measure soil respiration fluxes were selected to simulate and analyze the soil respiration fluxes of Quercus mongolica forest. The paper tries to explore the advantages and disadvantages of the three methods, in order to provide some reference value for the research in related fields.
