概括

土壤碳研究主要集中在有机碳 (SOC),忽视了无机碳 (SIC),尽管全球有类似的库存. 增加对SIC的研究对于准确的气候变化建模和缓解努力至关重要.

科学领域:

土壤科学土壤科学
环境科学环境科学
地质化学地质化学

背景情况:

土壤是全球碳循环的关键调节者,充当碳汇或碳来源.
陆地土壤碳存在于有机 (SOC) 和无机 (SIC) 池中,具有不同的环境作用.
全球研究不成比例地集中在SOC上,很大程度上忽视了SIC.

研究的目的:

用图书统计分析量化全球土壤碳研究趋势.
评估 SOC 与 SIC 池的比例研究重点.
突出SIC在研究,应用和气候变化模型中的代表性不足.

主要方法:

对土壤碳出版物和引用的图书统计分析.
对SOC和SIC (2020-2023) 的研究主题的趋势分析.
根据国家和合作模式对研究贡献的比较评估.

主要成果:

土壤碳的研究跨越了一个多世纪,有超过47,000个出版物.
SOC在研究中占主导地位 (>96%的出版物/引用),而SIC获得的关注度很小 (<4%).
尽管焦点较低,但SIC研究显示气候变化影响 (每文档引用) 比SOC更高.

结论:

SIC研究的显著代表性不足可能导致全球碳循环的不完全理解和建模.
由于农业造成的加速SIC损失,需要更多地关注气候变化减缓的研究.
扩大SIC研究对于实现"巴黎协定"气候目标和准确地表示全球碳预算至关重要.

The Carbon Cycle

The Carbon Cycle

Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

The Soil Ecosystem

The Soil Ecosystem

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:
