Implication

Modeling study reveals spatiotemporal soil organic carbon accumulation across China, highlighting depth-dependent climate and vegetation drivers of carbon sinks.

Key Points

Investigate the spatiotemporal dynamics of soil organic carbon across different soil depths from the 1980s to the 2010s and determine the relative influence of key environmental drivers.
Applied machine learning algorithms to model soil organic carbon dynamics across multiple soil layers throughout China from the 1980s to the 2010s.
Conducted factorial simulation experiments to isolate and quantify the impacts of climate change, vegetation dynamics, and environmental variations.
Total soil organic carbon stock in the upper meter reached 80.68 ± 3.49 Pg C during 2000–2014, with the top 20 cm storing 42.6% and sequestering carbon at 30.80 ± 12.37 g C m⁻² yr⁻¹ since the 1980s.
Climate change was the primary driver of soil organic carbon dynamics, with warming and drying inducing carbon loss; its influence declined with soil depth, whereas the influence of vegetation growth increased.
Cropland topsoil organic carbon increased at a rate of 23.6 ± 7.6 g C m⁻² yr⁻¹ since the 1980s, largely driven by nitrogenous fertilizer application.
