Understanding the movement and alteration of carbon and nitrogen elements in soil is crucial for addressing ecological restoration in coal mining subsidence areas. However, the migration process and mechanisms of these elements during the natural restoration process remain unclear. This study analysed the fluctuating variations and formation mechanisms of TC and TN content in soil profiles at different restoration times in coal mining subsidence areas. Initially, both TC and TN contents decreased followed by an increase during the natural restoration process. Soil compaction effects, variation of C/N ratio, and soil enzyme activity were considered as predominant factors controlling carbon and nitrogen element cycles in collapsed soil profiles. This study will provide valuable insights into understanding the mechanisms behind carbon and nitrogen cycles during natural recovery while establishing a scientific basis for ecological restoration in coal mining subsidence areas.
