摘要
Soil,as the largest terrestrial organic carbon reservoir,contains approximately 1500 petagrams of organic carbon in its top meter.This amount is roughly twice the carbon stored in the atmosphere and three times that in vegetation[1].Enhancing soil organic carbon(SOC)storage is an effective strategy for mitigating climate change.Moreover,SOC is a key indicator of soil quality and ecological health and plays a central role in the global carbon cycle.Given increasing concerns over global warming,food security,and environmental sustainability,accurately quantifying SOC at large scales with high spatial resolution and precision is essential.
