泥炭地土壤呼吸的影响因素及时空变异

Influencing factors and spatial-temporal variation of soil respiration in peatland

  • 摘要: 土壤有机碳库是全球碳循环的重要组成部分,而泥炭地作为重要的土壤碳库,在全球碳循环中发挥着关键作用。泥炭地土壤呼吸是泥炭地碳循环的重要过程,在气候变化背景下,其对碳平衡和气候变化的影响引起了广泛关注。在此对全球泥炭地土壤呼吸产生影响的生物及非生物因素、时间空间变化等方面的研究进展进行综述,了解和预测泥炭地生态系统对环境变化的响应及其反馈,并讨论其未来的发展方向,以期对未来泥炭地保护提出一定的方向。预计将在全球气候变化的背景下,为泥炭地碳循环和全球气候变化的深入理解、区域碳循环预测等方面提高科学依据为泥炭地生态系统的管理和保护提高重要参考。

     

    Abstract: Soil organic carbon pool is an important part of global carbon cycle. As an important soil carbon pool, peatland plays a key role in global carbon cycle. Peatland soil respiration is an important process in the peatland carbon cycle, and its impact on carbon balance and climate change has attracted widespread attention in the context of climate change. This paper reviews the progress of research on biotic and abiotic factors and temporal and spatial variations affecting soil respiration in peatlands around the world, understands and predicts the response of peatland ecosystems to environmental change and their feedbacks, and discusses their future directions, with a view to suggesting certain directions for peatland conservation in the future. It is expected to provide a scientific basis for the management and protection of peatland ecosystems, provide an important reference for an in-depth understanding of the peatland carbon cycle and global climate change, and be of great significance for the prediction of regional carbon cycle in the context of global climate change.
