青藏高原森林土壤有机碳储量空间分布格局研究现状

Research Status of the Spatial Distribution Pattern of Forest Soil Organic Carbon Stocks in the Qinghai-Xizang Plateau

  • 摘要: 青藏高原作为全球生态系统的重要组成部分,是气候变化的敏感区和重要的生态屏障,其森林土壤中的SOC储量对于全球碳循环具有显著影响。文章旨在综合分析当前青藏高原森林土壤SOC储量的空间分布格局及其影响因素。主要阐述了土壤SOC储量的常用估算方法,揭示了青藏高原不同区域土壤SOC储量的分布特征。分析发现,青藏高原土壤SOC储量呈现出明显的空间异质性。此外,文章还探讨了气候条件、人类活动和土壤性质等因素对土壤SOC储量分布的影响,并提出了相关展望。

     

    Abstract: As an important part of the global ecosystem, the Qinghai-Xizang Plateau is a sensitive area to climate change and an important ecological barrier, and the soil organic carbon stock in its forest soils has a significant impact on the global carbon cycle. This paper aims to comprehensively investigate the spatial distribution pattern and influencing factors of forest soil organic carbon storage in the Qinghai-Xizang Plateau. The common methods for estimating soil organic carbon stocks are described, and the distribution characteristics of soil organic carbon stocks in different regions of the Qinghai-Xizang Plateau are revealed. It was found that soil organic carbon stocks in the Qinghai-Xizang Plateau showed obvious spatial heterogeneity. In addition, the effects of climatic conditions, human activities and soil properties on the distribution of soil organic carbon stocks are discussed, and relevant prospects are proposed.
