Soil organic carbon dynamics can be reflected to some extent by the soil quality magnetic susceptibility and root content.

土壤磁化率、根生物量在一定程度上可以反映土壤有机碳动力学过程。

Land use change is still a major source of carbon dynamics emission due to burning and cultivation, which caused to decline soil organic carbon contents in soils and degrade soil quality.

因烧垦而引起的土地利用变化仍然是碳素释放的主要来源，从而导致了土壤有机碳含量下降和土壤质量退化。
