Drainage induced mid-deep peat subsidence and the implication

In this study, four types of drained peatlands (slight-drained peatlands, light-drained peatlands, moderate-drained peatlands and deep-drained peatlands) were selected in order to quantitatively evaluate the degree of peat subsidence at different depths, as well as the changes in peat carbon stock, decomposition potential and Q10. Meanwhile, we synthesized 915 observations from relevant studies and used meta-analysis to reveal the universal effect of drainage on peat carbon loss.
